  modified high temperature nylon (PPA)

poly 邻苯二甲酰 amine （简称PPA） is types semi crystallization property thermoplastic property aromatic polyamide (PA), aromatic high temperature nylon, long as temperature degree can 达180 degree, short resistant temperature can 达290 degree, tool has high modulus, high hardness, high property ratio, low water absorption, dimensional stability and excellent can welding property and other advantages. PPA材 material tool has excellent comprehensive material property, in hot, electrical, material and chemical resistance 方面都 has good performance, especially is in high temperature lower still tool has high strength and dimensional stability

PPA材 material property can features

PPA is types high temperature resistance material, its melting point 介于310-325℃ between, heat deflection temperature (HDT) 介于280-290℃.

PPA oil resistant property excellent, for 燃油, lubricated and other various type has resistant property, make in 150 ℃ high temperature lower 亦如此

PPA tool has dimensional stability and low warpage property

PPA water absorption ratio PA6 or PA66 low very more, make is in cold water in 浸泡几 year time, its tensile strength can maintain 80% above

PPA tool has resistant property, in high UV辐射, high wet, high temperature and other gas conditions lower, combined long 期 室 outer use

PPA tool has excellent environmental protection property can, can to USA FDA grade
