EPDM
It is named Ethylene Propylene Diene Monomer, but it is also called Ethylene Propylene Rubber.
It was first produced in 1963 as a copolymerization of ethylene and propylene.
Due non-existence of double bond in reaction, it has fully saturated structure.
This allows the rubber to develop resistance against ozone and oxygen.
EPDM is obtained by adding a third diene to the reaction, apart from the ethylene and propylene.
Properties:
High resistance against heat, light and oxidation.
Mixtures are created with relatively lower costs, thanks to its high capacity of extender oil absorbing capacity.
Resistance against acids and bases.
Resistance against hydraulic brake liquids.
Provides resistance against external effects, ozone, saltwater, hot or cold water.
Areas of Usage:
Seals of doors and windows, sponge seals, radiators and heating hoses.
Used in domestic appliances, automotive industry and food industry.
Operating Temperatures:
Long term: -30 C° + 125 C°
Short term: -40 C° + 170 C°
