  ]]> ISO 10993 and USP Class VI both define testing requirements for biocompatibility, the ability of a material to perform a desired function without causing adverse effects on the human body. By ensuring that a material is non-toxic and won’t result in immunological rejection, biocompatibility testing ensures that a rubber is safe for use with living tissue. Examples of these materials include the ISO 10993 and Medical Molding

  ISO 10993 is an international standard that divides medical devices into three categories: surface, implant, and external communicating. Based on the time of exposure, these categories are further divided into three subcategories: limited, prolonged, and permanent. Before selecting a molding material such as a medical silicone, it’s important to determine which category and subcategory describes your application. Otherwise, you won’t know which testing protocol applies. ISO 10993 is not a checklist, but it does provide a risk-based guide for evaluating different materials.

  Yet, ISO 10993 is more than just a framework for material identification. This standard also provides a way to identify and quantify a material’s chemical ingredients. There are several important uses for chemical characterization, each with a numbered designation. For example, ISO 10993-1 and ISO 10993-14971 are used as part of an assessment for the overall biological safety of a medical device. By contrast, ISO 10993-17 measures the level of a leachable substance. As an experienced medical molder, The Rubber Group works with independent laboratories like NAMSA to understand these requirements.

  USP Class VI and Biocompatible Rubber

  USP Class VI refers to a set of biocompatibility testing requirements from the U.S. Pharmacopeia (USP), a non-profit organization whose standards inform decision-making at the U.S. Food and Drug Administration (FDA). Specifically, USP publishes test instructions for the plastics, polymers and elastomers that are used in medical devices and surgical equipment. These tests correspond to numbered classes and use different extracts, such sodium chloride and alcohol saline. Among USP classes, Class VI materials meet the toughest testing requirements.

  USP Plastic Class VI, as this group is also known, covers materials that pass a systemic toxicity test, an intracutaneous test, and an implantation test. These tests are directly related to the intended end-use of the article and account for conditions such as patient contact time and temperature. Some suppliers claim to use USP Class VI compliant ingredients but may not be able to ensure the compliance of their end product. The Rubber Group can source materials that have a certificate of conformance (COC) from a third-party testing laboratory or that have a certificate of compliance (COA) from the material’s supplier. Testing can be expensive, so it pays to work with a medical molder who can source products with existing certificates.  We also offer a choice medical molding services.

If you’re comparing rubber injection molding to other manufacturing processes, remember to consider tooling costs, cycle times, and process validation for critical medical parts. 

  The Medical Injection Molding Process and Project Costs

  Rubber injection molding for medical devices feeds a ribbon-like strip of uncured rubber into a rotating screw. The screw feeds a precisely controlled amount of rubber into the injection chamber for pre-heating and plasticization. The rubber is then injected into a mold cavity though a gate and runner system. To achieve vulcanization, the elastomer is held under high pressure at an elevated temperature. When curing is completed, the injection molded parts are removed or ejected from the mold’s cavities.

  The metal mold that is used can cost less than an equivalent transfer mold; however, the size and complexity of the part may require higher production volumes for mold cost amortization. With injection molding, tools for Injection Molding Materials, Products, and Process Validation

  Medical injection molding supports the use of a wide variety of elastomers, including EPDM and nitrile �just to name a few. Silicones, a group of synthetic elastomers, are used in many medical gaskets and rubber products such as medical grommets for middle ear treatments and O-rings for IVs, drug delivery, and dialysis.

  ]]> What is USP Class VI? 

  The USP Class VI classification demonstrates that the materials and processes used to produce an end article are safe and will meet stringent biocompatibility specifications for medical devices and related applications. Specifically, USP VI testing evaluates the biological reactivity of materials and ensures they are safe for use where contact with human tissues and fluids is possible.  

  How are USP Class VI Elastomers Tested? 

  There are four aspects to USP VI testing. 
  • In vitro testing 
  • Biological reactivity testing 
  • System injection test 
  • Implantation test 
  The following sections explain.  

  In Vitro Testing 

  In vitro testing exposes the USP Class VI material to a series of extraction solvents that simulate various physiological conditions. These solvents may include polar and non-polar substances such as saline solution, vegetable oil, and ethanol. The material is immersed in these solvents to simulate the potential interaction between the material and bodily fluids. 

  Biological Reactivity Testing 

  In biological reactivity testing, the extracted solutions are then subjected to various biological tests using sensitive test systems. Specifically, these tests assess the degree of biological reactivity and the potential toxicity of substances that have leached from the USP VI material. These tests may include evaluating cell cultures and assessing the potential for irritation or other adverse effects.  

  System Injection Test 

  The system injection test injects the extracted material intravenously into test animals. The animals are then observed for signs of systemic toxicity, and this test helps evaluate the potential adverse effects of substances that may have leached into the solution. 

  Implantation Test 

  During the USP Class VI implantation test, the material is implanted into the tissues of living animals. The goal is to observe the long-term effects, including inflammation or other adverse reactions that may occur when the material is in direct contact with living tissue.  

  Choose Fully Compliant USP VI Elastomers 

  Rubber materials can be formulated to meet USP VI, but they’re not fully compliant until they are properly tested. As an experienced medical molder, The Rubber Group works with a range of independent laboratories to understand these requirements and can provide you with certified results.   Testing can be expensive, so it pays to work with a medical molder who can source products with existing certifications to reduce your product launch costs.

  ]]> Why rubber bellows are critical components in a variety of industries

  Flexibility: Bellows can expand and contract while maintaining their structural integrity. This makes them ideal for applications where movement, misalignment, or vibration needs to be accommodated, such as in automotive steering systems and HVAC ducts.

  Sealing and Protection: They are excellent at sealing against dust, dirt, moisture, and other contaminants that could lead to premature wear or damage. In hydraulic and pneumatic systems, rubber bellows help keep vital components protected from external elements.  Bellows are critical to the protection of drive systems to ensure smooth and reliable operation in dirty environments. 

  Compensation: Bellows are adept at compensating for Why rubber is an ideal bellow material

  Elasticity: Rubber possesses natural elasticity, allowing it to return to its original shape after being stretched or compressed. This property ensures that rubber bellows can withstand repeated movements without losing effectiveness.

  Resistance: Rubber is resistant to a wide range of environmental factors, including chemicals, UV radiation, and ozone. This makes it a durable choice for outdoor and industrial applications.

  Sealing Properties: Rubber has a natural ability to create an effective seal, which is crucial in applications where leakage is not permissible.

  Cost-Effective: Rubber bellows are generally more affordable than bellows made from some other materials, making them a cost-effective solution for various industries.  Rubber is an ideal material for regular flexing due to it’s ability to recover without breaking down. 

  Considerations when designing rubber bellows

  Environment: Consider the operating environment, including temperature, chemicals, and exposure to UV radiation. If the bellows will come into contact with chemicals, it’s essential to ensure that the chosen material is chemically compatible and won’t degrade or react adversely.

  Movement: Determine the range and frequency of movement the bellow will experience; speed can also be a factor to consider.

  Sealing Requirements: If sealing is essential, choose a material with excellent sealing properties. Rubber is typically a good choice for sealing applications.

  Size and Shape: Consider the size and shape of the bellow to ensure it fits within your system without interference.  Shapes can be irregular, complicating the performance and, therefore, the design of the resulting bellow. 

  Challenges when molding bellows

  De-molding: The demolding procedure is an often ignored component of producing molded components. It is critical to have a solution in place for de-molding hollow parts with convolutions.  Improper de-molding will increase scrap costs, leading to an increased purchase price.  It has the potential to deform or improperly stress the part, leading to failures in operation.  An experienced bellows producer such as The Rubber Group knows how to avoid these pitfalls.   

  Material Selection: Selecting the right rubber compound is crucial, as different types of rubber offer varying levels of flexibility, resistance, and durability.  A partner such as The Rubber Group, which has a complete stable of ready-to-use compounds, ensures the right compound for the right application. 

  Quality Control: Maintaining consistent quality across a production run is essential to ensure that each bellows performs reliably in its intended application.  As noted above, quality is more than just inspection.  Understanding the entire supply chain and molding process is critical to ensure the part is right the first time, every time.  At The Rubber Group we pride ourselves on making sure this is correct the first time, every time. 

  Ask The Rubber Group about Bellows

  Rubber bellows may be hidden heroes in the world of sealing components, but their importance cannot be overstated. Their flexibility, sealing capabilities, and resistance to environmental factors make them indispensable in numerous industries. While alternative materials offer solutions for specialized needs, rubber is the go-to material for most applications.  When choosing a bellow producer or supplier, finding a partner who can deliver quality parts at an affordable price that meets the needed application is important.  The Rubber Group continues to be an industry-leading supplier of rubber bellows.  Send us your next project or your current part to quote!

  Silicone Sterilization Mats 

  Typically, sterilization mats are made of silicones, moisture-resistant elastomers that come in softer durometers and resist chemical and thermal degradation while maintaining their properties under extreme temperatures. The most common medical sterilization methods are moist heat (steam), dry heat, radiation, ethylene oxide (EtO) gas, and vaporized hydrogen peroxide. Chlorine dioxide gas, vaporized peracetic acid, or nitrogen gas are sometimes used instead.    

  

  Silicone Mats for DIN Trays 

  To hold and cushion items, silicone sterilization mats contain raised structures that are often called fingers or nubs. Typically, they’re shaped like circles, cylinders, triangles, or diamonds. They’re also spaced uniformly apart and can have openings between them. Importantly, sterilization mats are designed to fit within a specific size of sterilization tray or container. The most common sizes refer to DIN EN 285:2016, a specification for steam sterilization. Most DIN trays come in half, full, one-quarter, and three-quarter sizes.

  ]]> Rubber product validation is an important part of sealing material selection because designers need to know that a rubber seal will perform properly over the long term. Previous parts of this Sealing Material Selection Guide introduced some commonly used rubber materials (Part 1), material properties (Part 2), and product testing requirements (Part 3). Now that you know this information, it’s time to learn about rubber product validation and its relationship to variation.     

  There are multiple sources of variation in the production of rubber sealing products: machines, tools, operators, materials, environments, measurement techniques, etc. Developing a robust validation plan is critical to controlling these sources of variation and ensuring the long-term goals of your sealing system. Knowing the critical features of the seal is part of controlling them properly in the process. Keep reading to learn more, or contact The Rubber Group to discuss the molded rubber parts that you need.

  How to Ensure Long Term Part Performance

  The table below lists items that are important to consider for product validation.

  Validation Item	Description
  Critical to Quality Items (CTQs)	Identifying the dimensional and/or material properties that are critical to your system’s function is crucial to developing a robust rubber product validation plan.
  Gage Repeatability and Reproducibility (Gage R&R)	Verifying that the measurement system can effectively evaluate parts in a consistent manner without operator variation in results guarantees that accurate results will be achieved in the long term.
  Process Capability	Acceptable process capability on CTQs is a robust way to verify that any variation in the process, tooling, and materials is captured in the data. This ensures that the rubber molder will be able to deliver in-spec parts over the long term. Sometimes, this could mean running multiple lots of material, multiple changeovers and/or different operators to capture all sources of variation.
  Production Part Approval Process (PPAP)	Documenting the dimensional, material and performance results in one package helps to ensure that all of this information is available in the future. Process flows, control plans, and Process Failure Mode and Effects Analysis (PFMEAs) ensure change and risk control over the process.
  Medical Validation – IQ/OQ/PQ (Installation Qualification, Operational Qualification, and Performance Qualification	As a requirement for most medical projects, IQ/OQ/PQ is a very thorough way of ensuring supplier/customer agreement on the process and results. Processes are run at high and low gates for critical process parameters and tested accordingly. The other sources of variation are also included. The Rubber Group applies aspects of this process to non-medical parts as a best practice when warranted by the complexity and criticality of the application.
  System Validation Testing	Taking parts from the extremes of manufactured variation and testing them in the end process validates that the entire system will work as intended at all process extremes.
