三元乙丙橡胶是一种高性能合成橡胶, 主要成分为乙烯, 丙烯和少量非共轭二烯。以下是其性能:
高温稳定性. 三元乙丙橡胶具有优异的耐热性, 长期使用温度 120 ℃ 至 170 你C, 短期使用温度 200 你C.
耐老化. 具有良好的耐老化性能, including ozone resistance, 天气抵抗, ETC。, keep long-term use without discoloration.
耐腐蚀. EPDM rubber has good resistance to polar chemicals such as acid and alkali, alcohol, oxidant, ETC。, but not resistant to fatty hydrocarbons and aromatic hydrocarbons, poor stability in gasoline.
Elasticity. EPDM rubber has good elasticity, can maintain stable performance in complex stress environment.
Physical properties. Its tensile strength and elastic modulus are relatively stable physical properties, with good mechanical properties.
电绝缘. EPDM rubber also has good electrical insulation performance, suitable for electricity, communications and other fields.
Steam resistance. It has excellent steam resistance, and can still maintain at high temperatures.
Low density high filling. EPDM rubber has low density, can be filled with oil and added fillers in large quantities, helping to reduce the cost of rubber products.
EPDM is widely used in automotive parts, 建筑防水材料, wire and cable sheath, heat-resistant hose, adhesive tape, automotive seals and other fields. It is also suitable for making tires, industrial belts, sealing products, hose and other industrial products, as well as sports equipment and recreational rest areas.
