| Rubber used by Confind | ||
| Rubber type | Technical characteristics | Nitrile rubber (butadiene-acrylonitrile) | NBR | Good resistance to oil, good gas impermeability, good resistance to wear. Temperature range -30 to +120 °C; -40 to +90 °C. | Hydrogenated Nitrile Rubber | HNBR | Good resistance to oil and corrosive environment (up to 20÷ H2S + CO2). For temperature range -50 to +150 °C. | Fluorinated Rubber | FPM | Good resistance to petroleum products, aliphatic hydrocarbons, aromatic solvents. For temperature range -20 to +230°C. | Chloroprene Rubber | CR | Average oil resistance, good resistance to ozone, heat and atmospheric agents. For temperature range -30 to +110 °C. | Ethylene propylene rubber | EPDM | Good resistance to ozone, heat, water, acids and bases, good flexibility at low temperatures. For temperature range -40 to +110 °C. | Silicone rubber | VMQ | Very good resistance to dry heat, dielectric qualities, flexibility at low temperatures, not resistant to gasoline and diesel. For the temperature range of -60 to +200 °C. | Natural rubber and styrene-butadiene | NR;SBR | General purpose medium heat resistance, good flexibility at low temperatures, not resistant to petroleum products (NR). For temperature range -40 to +70 °C. |
