seal suitable environment for different occasions, the rubber seals sealing ring material is different, use temperature range will be constrained by different. Chloroprene rubber seals seal good light resistance, weather resistance is strong, of dichlorodifluoromethane and ammonia refrigerant resistant, resistance to dilute acid, silicone oil, resistance at low temperature, easy to crystallization, sclerosis in aniline point expansion amount of mineral oil with low. Do not recommend in acid, nitro hydrocarbon, chloroform, esters, ketones and other chemicals in use. Generally in the sunlight, ozone, atmospheric exposure range is larger, resistance to chemical corrosion, flame environment for sealing function, temperature in - generally use 55 to 120 ℃. Silicon rubber sealing ring has good insulation, but for the cold resistant, resistant to ozone, heat resistance, resistance to atmospheric aging performance is better. Its disadvantage is not resistant to oil, tensile strength is weak. In a concentrated solvent, concentrated acid, sodium hydroxide is not recommended and used in the oil, commonly used in household appliances and products in contact with the human body. In general use temperature - 55 to 250 ℃. Epdm seal high and low temperature resistant anti-aging can be used in the solvents such as alcohols, ketones, do not recommend the use of food and mineral oil, commonly used in the sanitary equipment, automobile brake system and auto radiator. In general use temperature - 55 to 150 ℃. Acrylate rubber seal better high temperature resistance, weather resistance, more outstanding performance is the oil resistance, but the compressibility, water resistance and mechanical strength is weak, and is not recommended in the brake oil, hot water and phosphate used, generally use temperature in - From 25 to 170 ℃. Epdm production of sealing ring based on the characteristics of ethylene propylene rubber high and low temperature resistance, its production and the temperature of the sealing ring are - Between 50 ℃ to 150 ℃.
