PPA characteristics:
PPA has superior strength, toughness and hardness, as well as good heat resistance, chemical resistance and crack resistance
PPA can still maintain strength and hardness under high temperature and high humidity environment, so it can replace metal in traditional nylon and polyester that cannot be used at will
PPA plastic also has superior surface luster. It can be colored to avoid surface spraying, thus helping to reduce the apparent degree of surface scratches and scratches.
PPA plastic also has good processability and allows short injection cycle time
