Parker's 70 Durometer, Rust Silicone Mil/Aero (S1224-70 ZZ-R) (VMQ), S1224-70, has 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.
Temperature Range: -65°F to 450°F (-54°C to 232°C)
