The neoprene rubber gaskets that A.J. Rubber & Sponge Ltd. produces are composed of a very versatile rubber used in a wide variety of applications ranging from the medical to construction industries. Neoprene rubber seals and gaskets resist degradation from ozone, sunlight and poor weather conditions. Since they are synthetic, neoprene rubber gaskets also tend to perform extremely well when in contact with oils and other various chemicals. Neoprene rubber gaskets always maintain their tensile strength and form over very wide temperature ranges, much like EPDM (Ethylene Propylene Diene Monomer) rubber gaskets and silicone rubber gaskets.
