SI70OR82 is a 70 shore A orange silicone (VMQ) compound that is peroxide cured and manufactured to AMS 3304, AMS 7268, and A-A-59588 (2A-70 and 2B-70) specifications for high temperature sealing applications. This material provides excellent performance in O-rings and gaskets exposed to extreme heat, maintaining stability up to 315°C while retaining flexibility down to -54°C. It offers strong resistance to ozone, detergents, salt water, and vegetable and animal oils, making it well suited for aerospace, industrial, and environmental sealing environments. SI70OR82 meets ASTM D2000 7GE707 requirements and can be compared to Parker S0604-70 when evaluating equivalent high temperature silicone materials.
Silicone rubber, commonly referred to as VMQ, is widely used in O-rings and gaskets due to its exceptional temperature range and resistance to environmental degradation. High temperature silicone grades are specifically formulated to withstand prolonged exposure to elevated temperatures while maintaining elasticity and sealing performance. These materials are commonly used in aerospace, automotive, and industrial applications where thermal stability and ozone resistance are critical. While highly versatile, silicone compounds are generally not recommended for use with petroleum fuels or certain aggressive chemicals, making proper material selection important.
