Common Name | Chemical Name | Tensile/Elong. | Temperature Range (F) | General Properties |
Natural Rubber | Natural Isoprene | 3200/800 | -65 to +212 | Good physical properties, good resistance to abrasion. Fair resistance to weather and ozone exposure. Excellent non-oil resistance to rubber compound designed to resist flow under compression. Standard for gasket cutting in plumbing trade and general purpose use against water, air and low pressure steam. |
Black & Red Rubber | SBR Styrene Butadiene | 700/300 | -65 to +250 | Excellent physical properties including abrasion, tear strength and soft rubber seal where applied pressures are light. Resists most inorganic salts, ammonia, acids, and alkalis. Non-toxic and non-marking. |
C.I Rubber | SBR Styrene Butadiene | 700/300 | -65 to +250 | Same as above except cloth inserted to prevent creep in flanges. |
Butyl SBR | Butylene Isoprene | 1500/500 | -40 to +300 | Good weathering resistance. Excellent dialectic properties. Low permeability to air. Resists effects of many acids, alkalis and ozone at moderately high temperatures. |
EPDM | Ethylene Propylene | 1650/450 | -90 to +035 | Hydrocarbon rubber having excellent resistance to heat aging, oxidation, ozone, acids, alkalis, hydraulic fluid and electrical sensitivity. |
Buna-N | Nitrile Butadiene | 1000/400 | -40 to +200 | Commercial grade general purpose sheet for extreme exposure to oil, arpmatic and hydrocarbon solvents. |
Neoprene | Poly-chloroprene | 100/400 | -40 to +200 | Commercial grade general purpose sheet with good oil and weather resistance properties. Excellent for mounting pads, diluted acids and alkaline applications. |
Hypalon | Chloro-Sulfinated Polyethylene | 2400/400 | -40 to +300 | Excellent acid resistance such as sulfuric acid and hypo chlorite solutions, outstanding weather, oil, abrasion, flame and heat resistance. |
Urethane | Polyurethane | 4000 | -40 to +250 | Highest available abrasion resistance, strength amd load bearing capacity. Excellent oil and solvent resistance. |
Silicone | Dimethyl-polysiloxame | -165 to +500 | Outstanding high and low temperature range. Odorless, tasteless, non-corrosive and non-contaminating. | |
Viton Fluorinated | Hydrocarbon | 2250/300 | -40 to +400 | Unsurpassed for service in oils, fuels, solvents and many chemicals; such as carbon tetrachloride, tuluene, benzene and xylene. |
