SI60OR50 is a 60 shore A orange silicone (VMQ) compound designed for high temperature sealing applications where long-term durability and compression set resistance are critical. This material offers excellent resistance to thermal degradation along with strong performance against oxygen, ozone, and UV exposure, making it ideal for O-rings and gaskets used in aerospace, industrial, and outdoor environments. It maintains reliable sealing performance across a service temperature range of -55°C to 235°C and meets ASTM D2000 and A-A-59588 (2B-60) requirements. SI60OR50 can be compared to Parker S0613-60 and S0383-70 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 broad temperature range and excellent environmental resistance. These materials maintain flexibility at low temperatures while remaining stable at elevated temperatures, making them well suited for applications involving thermal cycling and harsh environmental exposure. Silicone compounds are commonly used in aerospace, medical, and general industrial applications where ozone resistance, weatherability, and longevity are essential. While highly versatile, they are generally not recommended for use with petroleum fuels or certain aggressive chemicals, making proper material selection important for optimal performance.
