聚偏氟乙烯树脂被认为是仅次于PTFE的第二含氟树脂,是一种综合性能良好的含氟高分子材料,具有含氟树脂的共同特性,如优良的热稳定性、耐腐蚀性、不燃性、耐紫外线性等性能。同以PTFE为代表的其它含氟树脂相比具有最高的抗张强度和抗压缩强度、最优的刚性、耐磨耗性和耐切割性、熔点较低、熔融流动性好等优点。可以用普通树脂的加工方法、加工机械进行模塑、挤塑、注塑、吹塑加工
High max. allowable service temperature in air (150°C continuously)
Good mechanical strength, stiffness and creep resistance (better than other
fluoropolymers)
Excellent chemical and hydrolysis resistance
High toughness, also at low temperatures
Good sliding properties and wear resistance
Good dimensional stability
Physiologically inert (suitable for food contact)
Good electrical insulating properties
Outstanding UV and weather resistance
Inherent low flammability
Fairly good resistance against high energy radiation (much better than other
fluoropolymers)
PVDF is a highly crystalline unreinforced fluoropolymer combining good mechanical, thermal and electrical properties with excellent chemical resistance. Its property profile makes PVDF a versatile engineering material, especially suitable for the manufacture of components for the petrochemical, chemical, metallurgical, pharmaceutical, food, paper, textile and nuclear industries. |
