Raw Material | Uses | Advantages | Disadvantages | Hardness (Shore A) | Operating Temperature (°C) |
Viton | Seals, gaskets in the chemical industry | High resistance to heat, chemicals, ozone | Relatively expensive, difficult to process | 60-90 | -20 to +250 |
Silicone | Seals, food gaskets, personal care products, medical devices | High heat resistance, good flexibility, ozone resistance | Less resistant to certain chemicals like oils and fuels | 20-80+ | -60 to +200 |
Urethane | Gaskets, springs, padding, medical devices | High flexibility, wear resistance, high mechanical properties | Sensitive to UV light, may crack under harsh conditions | 60-95 | -40 to +80 |
Nitrile (NBR) | Seals, filters, hoses, automotive gaskets | Resistant to oils and fuels, high flexibility, resistant to wet environments | Sensitive to ozone and high temperatures, not resistant to certain harsh chemicals | 50-80 | -40 to +100 |
Neoprene | Covers, diving suits, seals, pads | Resistant to ozone, water, and some chemicals, good flexibility | Less resistant to oils and fuels, may dry out over time | 40-80 | -40 to +100 |
EPM/EPDM | Automotive gaskets, seals, insulation materials | Resistant to ozone and heat, high flexibility | Not resistant to oils and fuels, less flexible than others | 40-80 | -40 to +120 |
Butyl | Automotive gaskets, seals, covers, filters | High air and chemical resistance, high durability | Less flexible, not resistant to UV light, less elastic | 40-70 | -40 to +100 |
SBR | Rubber in the automotive industry, gaskets, pads | Low cost, good flexibility, good mechanical properties | Sensitive to ozone and heat, may dry out when exposed to air | 40-70 | -20 to +80 |
Natural Rubber | Gaskets, pads, consumer products, industrial rubber | High flexibility, excellent mechanical strength, easy to process | Sensitive to ozone, chemicals, and high temperatures, less durable over time | 30-60 | -20 to +70 |
