FDA Compliant | |
SI70RE04 is a red, metal detectable Silicone VMQ elastomer designed for demanding sealing applications involving O-rings, gaskets, and custom molded rubber components. This FDA compliant silicone compound meets the requirements of 21 CFR 177.2600 and is formulated using peroxide curing to support consistent physical properties and clean performance in food processing and hygienic environments. With a hardness of 70 Shore A, SI70RE04 provides a balanced combination of flexibility, sealing capability, and mechanical strength for static and light dynamic sealing applications.
This silicone material offers excellent resistance to ozone, detergents, salt water, vegetable oils, and animal oils, making it suitable for a wide range of industrial and sanitary applications where elastomer seals are exposed to cleaning chemicals and environmental aging. The service temperature range of -55°C to 205°C (-67°F to 401°F) allows reliable performance in both low temperature and elevated temperature sealing environments. SI70RE04 is commonly used for FDA compliant O-rings, gaskets, and custom silicone sealing components used in food processing equipment, beverage systems, pharmaceutical manufacturing, and sanitary fluid handling systems.
