Elastomers

Nitrite (generic name) rubber is the copolymer of butadiene and acrylonitrile. Trade names include Hycar, Chemigum, Paracril, Krynac and NY syn, Nitrite rubbers are highly resistant to non-polar oils and solvents but are swelled or dissolved by highly polar solvents. Vulcanizates are resistant to petroleum oils and fuels and essentially unaffected by alkaline solutions, salt solutions, aliphatic hydrocarbons, dilute acids, fatty acids and vegetable fats. They are swelled and attacked strongly by ketones, aromatics and concentrated oxidizing acids. Nitrite rubbers are resistant to crude oil, gasoline, fuel and petroleum based oils but are affected by acetones, amines, toluene, benzene and related compounds. Nitrite rubbers are molded at temperatures of 300 degrees Fahrenheit and above and are generally considered serviceable up to 250 degrees Fahrenheit. However, the usable life of cartridges made of Nitrite will be shortened substantially in continuous services above 150 degrees Fahrenheit.

EPDM (generic name) is a terpolymer of ethylene, propylene and diene. Trade names include Epsyn, Nordel, Vistalon, Epcar and Royalene. EPDM rubbers have outstanding resistance to oxygen, ozone, and heat. Vulcanizates are essentially unaffected by water, alkalines, some asides and diesters – they have poor to good resistance to aliphatic hydro carbons. They are swelled and attacked by aromatic hydrocarbons, ha logenated hydrocarbons, some alcohols and vegetable and animal oils. EPDM rubbers have fair to good resistance to heavy crude oil, acetone, amines, carbonic acid, detergents, ethylene glycol and 20% hydrochloric acid but are affected by butane, propane, bensene, concentrated hydrochloric and sulfuric acid. EPDM rubbers are formally molded at temperatures up to 350 degrees Fahrenheit: and are generally considered serviceable up to 300-350 degrees Fahrenheit. However, the usable life of cartridges made of EPDM will be shortened substantially in continuous service above 180 degrees Fahrenheit.

CHEMICAL REACTIONS OCCUR MORE RAPIDLY AS TEMPERATURES INCREASE, THEREFORE CARTRIDGES MAY HAVE A SHORTENED LIFE WHEN THEY ARE AFFECTED BY THESE HIGHER TEMPERATURES.
