SI50BU05 is a 50 shore A blue silicone (VMQ) compound that is peroxide cured and FDA compliant to 21 CFR 177.2600, making it ideal for food processing and general industrial sealing applications. Its lower durometer provides excellent flexibility and conformability, allowing O-rings and gaskets to achieve reliable sealing in low pressure systems and applications with irregular sealing surfaces. The material offers good resistance to ozone, detergents, salt water, and vegetable and animal oils, while maintaining stable performance across a service temperature range of -60°C to 205°C. SI50BU05 meets ASTM D2000 M5GE506 requirements and can be compared to Parker S1138-70 when evaluating equivalent FDA compliant silicone materials.
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. Lower durometer silicone materials like 50A are commonly selected for applications requiring flexibility, gentle sealing force, and improved surface contact. These materials are frequently used in food, beverage, and industrial applications where FDA compliance and long service life 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.
