Seals

EPDM

EPDM (Ethylene Propylene Diene Monomer) - known as Ethylene Propylene terpolymer, Buna-AP, Dutral, Polysar-EDM, Royalene, Vistalon, Keltan, Epcar, Nordel or Epsyn). Good for hot and drinking water, Steam, Freon refrigerant gas and Air -40°C to +120°C (+150°C steam) Poor resistance to oils + fuels

FKM (Viton)

FKM Fluoro elastomer (Fluorocarbon) Viton® Dupont registered, known as Tecnoflon, Fluorel, Dai-El. Good for hot water, acid, alkali, oils, hydrocarbons and salt solutions, many aggressive chemicals, diluted acids, weak alkali's, mineral oils, aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, sunlight and ozone. -26°C to +205°C. Poor resistance to Ketone's and Acetone.

NBR

NBR (Nitrile Buna Rubber) known as Nitrile Butadine, Buna-N, Hycar, Chemigum, Butakon, Breaon, Butacril, Paracil, Nipol, Perbunan, Krynac or Europrene-N. Good for Aliphatic Hydrocarbons, Petroleum, Fuels, Mineral Oil, Vegetable and Hydraulic Oil, Alcohol and many Acids. -35°C to +100°C. Poor for Ozone, Acetone, Methyl ethyl Ketone, Chlorinated Hydrocarbons, Ethers and Esters.

PTFE (Teflon)

PTFE (Polytetrafluoroethylene) also known as Teflon® Dupont registered. Excellent resistance to almost every fluid or gas. -200°C to +230°C

Voltalef

Voltalef known as PCTFE excellent chemical resistance, radiation resistance, and flammability characteristics, resistant to cold flow and it has the lowest coefficient of thermal expansion of any unfilled fluoropolymer. -240°C to +193.3°C.
