EPDM (ethylene propylene diene monomer) Rubber
Temperature Range -50 to +120°C dry conditions: with water & steam up to +130°C.
ADVANTAGES
Excellent weather resistance, as well as aging, ozone, chemicals, hot water & steam: good resistance to polar fluids such as acetone, methanol etc. outstanding electrical insulation properties, low steam permeability, good thermal resistance, extremely low brittleness temperature.
DISADVANTAGES
Low resistance to aliphatic & aromatic hydrocarbons (mineral oil, petrol, fuels); flammable.
