Silicone (VMQ) O-Rings
Silicone (VMQ) O-Rings
Silicone (VMQ) elastomers are ideal for high and low temperature applications. They have high heat and oxidative stability, outstanding low temperature flexibility, and are resistant to many chemicals.
Silicones have good ozone and weather resistance as well as good insulating and physiologically neutral properties. However, silicone elastomers as a group, have relatively low tensile strength, poor tear strength and little wear resistance.
O-ring applications can be very demanding. GFS Engineers are available to consult on any O-ring application. Click here to contact a GFS Engineer.
