PA66 gf25 for Radiator Electrical Automotive plug Connectors

1. PA66 plastic material is a translucent or opaque milky white crystalline polymer with plasticity. The density is 1.15 g/cm3. The temperature of 252 ° C. The embrittlement temperature is -30 °C. The thermal decomposition temperature is greater than 350°C. Continuous heat resistance 80-120 ° C, equilibrium water absorption rate of 2.5%. It can resist acid, alkali, most inorganic salt aqueous solutions, halogenated alkane, hydrocarbons, esters, ketones, etc., but is easy to contain polar solvents such as phenol and formic acid.

2. PA66 has a higher melting point in polyamide materials. It is a semi-crystalline crystalline material. PA66 also maintains high strength and stiffness at higher temperatures. PA66 is still hygroscopic after molding, the extent of which depends primarily on the composition of the material, the wall thickness and the environmental conditions. When designing a product, it is important to consider the effect of hygroscopicity on geometric stability.

3. The shrinkage rate of PA66 is between 1% and 2%. The addition of glass fiber additives can reduce the shrinkage rate to 0.2%~1%.
