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. |
