1. Description:
Polypropylene resin is white wax solid for injection molding.
Its strength, rigidity and hardness is high, and gloss.
Polypropylene also has good resistance to bending fatigue and good heat resistance
High frequency of polypropylene insulation performance is good, because it is almost not bibulous. Insulation performance is not affected by humidity. It has high dielectric properties, and increase with increasing temperature, can be used to make the heated electrical insulating paper.
2. Application:
PP injection molding products amount is large.
Common products: Basin, barrel, furniture, film, woven bag, bottle caps, bumper, television, radio shell, electric insulation, anti-corrosion pipes, plates, storage tank, flat silk, fibers, packaging film, pipe, washing machine frame and machine cover, the refrigerator door gasket, lawnmower, sprinkler D, etc.
