聚丙烯酸酯

材料选择指南

商品名称:

ASTM D1418名称:��ACM

ASTM D2000 / SAE J200类型,类:��DH; DF

苹果化合物名称:��PY

标准颜色:��Black

描述:��Polyacrylates are copolymers (ethyl acrylates) possessing outstanding resistance to petroleum fuels and oils.

键使用(S):��Sealing automatic transmissions & power steering systems. Sealing petroleum oils up to 350��F.

温度范围
Standard Compound: -25�� to +300��F

硬度(肖氏A):��40 to 90.

特征:��With excellent resistance to hot oil, automatic transmission and Type A power steering fluids, the greatest use for Polyacrylate is found in automobile manufacture, where O-rings of this material are employed to seal components of automatic transmission and power steering systems.

于阳光和臭氧降解高度抗性,聚丙烯酸酯还具有抵抗屈挠龟裂的增强能力。

限制:��While resistance to hot air aging is superior to Nitrile, Polyacrylate strength, compression set, water resistance properties and low temperature capabilities are inferior to many other polymers. Polyacrylates are also not generally recommended for exposure to alcohol, glycols, alkalis, brake fluids, or to chlorinated or aromatic hydrocarbons.
