Brief Summary |
Nitrile has good mechanical properties and high wear resistance relative to other elastomers. Unless they are specially compounded, nitrile is not resistant to weathering, sunlight and ozone. |
SBR is similar to natural rubber. SBR is mostly used in tires and seals for non-mineral oil based applications. |
Butyl has a very low permeability rate making it a great seal under vacuum. Butyl also has good electrical, shock dampening properties. |
Neoprene® exhibits good oil, ozone, weather, aging, refrigeration and chemical resistance. It also has good mechanical properties over a wide temperature range. |
Ethylene Propylene Copolymer has excellent resistance to phosphate ester fluids (Skydrol), brake fluids (glycol base), steam, weather, and ozone. |
Responds very well with resistance to ozone, high temperatures, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. The universal O-ring. |
Has excellent resistance to petroleum oils and fuels. Fluorosilicone has limited strength and abrasion resistance so it is generally recommended for static applications only. |
HNBR has excellent abrasion, compression set, tensile, and tear properties. Unlike standard nitriles, HNBR resists ozone, sunlight, and other atmospheric environments. |
Natural Rubber / Isoprene has excellent dynamic properties. However, it does not do well with petroleum oils, sunlight and ozone. |
Polyacrylate is used in applications such as transmissions or anything where there is petroleum oils and high temperature. Highly resistant to ozone and weathering. |
Silicon exhibits great temperature range capabilities. Silicones also has good resistance to ozone, weather and is also a good insulator. However, it has low tensile, tear and wear resistance. |
