Material Notes:

Black Silicone Rubber, 76-85 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. ASTM & ISO designation = VMQ. Formulated to meet UK Ministry of Defence Aircraft Materials Specification DTD5531A Grade 80. ASTM & ISO designation = VMQ.Applications: Sheets, mouldings and extrusions for mainly mechanical applications in contact with air within the quoted temperature range. They are not intended for liquid sealing or for application where low compression set is of prime importance. Occasional contamination by silicate ester and phosphate ester hydraulic fluids and greases is not unduly detrimental, provided the temperature is not excessive. Contact with fuels, light mineral oils, silicone liquids or greases derived from these should be avoided. Excellent ozone resistance.
