USP Class VI Silicone Rubber For Medical And Pharmaceutical Applications
What Is USP Class VI Silicone Rubber?
USP Class VI is a widely recognized material classification used for plastics, elastomers, and silicone materials intended for medical, pharmaceutical, laboratory, and healthcare-related applications.
The classification is based on biological reactivity testing described within the United States Pharmacopoeia and is commonly referenced when evaluating materials used in demanding healthcare environments.
For manufacturers supplying extruded silicone rubber components into medical and pharmaceutical applications, USP Class VI materials are commonly specified for products such as seals, customized gaskets, tubing, O-rings, and extruded profiles.
These materials may be used in equipment, processing systems, and devices where material performance and regulatory requirements are important.
Medical and pharmaceutical buyers may also reference USP Class VI Section 87 and 88, ISO 10993, and other application-specific requirements when selecting silicone materials.
