SI30RE02 is a 30 shore A red silicone (VMQ) compound that is FDA compliant to 21 CFR 177.2600, designed for soft, flexible sealing applications in food and industrial environments. Its low durometer provides excellent conformability, making it ideal for O-rings and gaskets used in low pressure systems or applications requiring enhanced surface contact and sealing efficiency. The material offers good resistance to ozone, detergents, salt water, and vegetable and animal oils, while maintaining reliable performance across a service temperature range of -60°C to 205°C. SI30RE02 meets ASTM D2000 M2GE303 requirements and is well suited for applications where flexibility, compliance, and environmental resistance are critical.
Silicone rubber, commonly referred to as VMQ, is widely used in O-rings and gaskets due to its broad temperature range and excellent environmental resistance. Low durometer silicone materials like 30A are particularly useful in applications requiring high flexibility and sealing capability under minimal compression force. These materials are commonly used in food processing, medical, and general industrial applications where FDA compliance and clean performance are required. While highly versatile, silicone compounds are generally not recommended for use with petroleum fuels or certain aggressive chemicals, making proper material selection important.
