E.P.D.M.
Excellent resistance to ozone and oxygen. The EPDM rubber based products are immune to oxidizing agents in both static and dynamic conditions, without adding antioxidant and antioxone agents.
Excellent resistance to degradation caused by the atmosphere.
Good resistance to high temperature (up to 150 °C) both in dry and damp rooms (preserved mixtures).
Good resistance to low temperature: the flexibility mantains down to -55 °C.
Excellent dielectric properties.
Very good hardness to permanent deformations.
Very good mechanical and elastic characteristics and preservation of this property.
Good resistence to various chemical materials (organic and inorganic acids, alkali, amines, phosphoric esters, hydraulic liquids, antifreeze liquids, pickles, bleaching agents, biodegradable and un biodegradable detergents, vegetal oils and fats) and polar solvents with short molecular weight (alkali, eters, ketones, glycols). The resistance to the hydrocarbon solvents and to mineral oils is low.
Low resistance to the propagation of a fuel if their formula is not right.
Very high impermeability to water.
