Selecting the correct elastomer material for the chemical composition of the process fluid is essential for optimum service life.
In many cases, process fluids will contain a variety of chemicals, and the elastomer selection should take into consideration all chemicals present.
These chemical recommendations are based upon field experience, polymer suppliers and laboratory tests. This information is offered only as a guide.
Generally resistant to oil and grease, moderate chemicals, fats, many hydrocarbons and ozone. Resistant to barnacle growth. -65 to 230F
Resistant to kerosene, moderate chemicals, fats, oils, grease and many hydrocarbons. -40 to 240F
Pure Gum Rubber is a high grade formulation of Natural Rubber with the same chemical resistance, but improved abrasion resistance, tensile strength and resiliency. Also suitable when dealing with organic acids, alcohols, ketones and most moderate chemicals. -65 to 180F
Good resistance to animal and vegetable fats, strong and oxidizing hemicals, oils, heat and greases. -65 to 250F
Resists strong acids and bases ozone, weathering, heat and oxidizing chemicals. -65 to 250F
Most effective for applications involving water, steam or diluted acids. -65 to 300F
Good resistance to animal and vegetable fats, strong and oxidizing chemicals, oils, heat and greases. -40 to 400F
TFE sheet or Teflon coated fibreglass used as a vapour barrier where condensation of corrosive gases may occur. -120 to 450F
A high quality elastomer, recommended for all environments except those with sulphur gas (SO2 or SO3). Usable in -70 to 500 degree applications. -160 to 500F
