SI60OR52 is a 60 shore A orange silicone (VMQ) compound designed for reliable high temperature sealing with strong compression set resistance and long-term durability. This material meets AMS 3303, A-A-59588 (2B-60), and ZZ-R-765 (2B-60) requirements, making it well suited for aerospace and industrial O-rings and gaskets exposed to elevated temperatures and harsh environments. It offers excellent resistance to thermal degradation, along with strong performance against oxygen, ozone, UV exposure, and fungal growth. With a service temperature range of -55°C to 235°C, SI60OR52 can be compared to Parker S0604-70 and S1224-70 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 ideal for aerospace, medical, and outdoor applications. Silicone compounds are particularly valued for their resistance to ozone, weathering, and aging, as well as their clean and stable performance in sensitive environments. While highly versatile, they are generally not recommended for use with petroleum fuels or certain aggressive chemicals, so proper material selection is important.
