|About EPDM Rubber
The main properties of EPDM are its outstanding heat, ozone and weather resistance. The resistance to polar substances and steam are also good. It has excellent electrical insulating properties.
EPDM rubber is commonly used in weather seals on all vehicles. This includes door seals, window seals, trunk seals, and sometimes hood seals. Frequently these seals are the source of noise due to movement of the door versus the car body. This is due to friction between the EPDM rubber and the mating surface (car painted sheet metal or glass). This can be alleviated using specialty coatings that are applied at the time of manufacture of the weatherseal, not as an aftermarket application. Such coatings can also greatly increase the chemical resistance of EPDM rubber.
In general, EPDM is especially used in cooling system circuit hoses in an automobile. Water pump, thermostat, EGR valve, EGR cooler, Heater, oil cooler, radiator and degas bottle is connected with hoses of which material is usually EPDM. Avon Automotive is one of the most famous company as a supplier of EPDM hoses for worldwide customers like Ford, Toyota, GM, Renault.
Additionally, EPDM can be used as charge air tubing on turbo charged engines. More specifically, it can be used to connect the cold side of the charge air cooler(aka "intercooler") to the intake manifold.
