PP has good heat resistance and low density. Its melting point is at around 165℃. It has high tensile strength and surface hardness and good environmental stress crack resistance. It can withstand 120℃ continuously.
Main Applications of Product
PP impact copolymer is widely used in the production of industrial products, such as dashboard, auto interior decorations, auto bumpers, interior and exterior parts of washing machine, accumulator containers and tanks. It can also be used to make household articles, such as bottle caps, cookware, furniture, toys, toolkits, travel cases, bags and various packaging containers.
Packages, Storage of Product
The resin is packaged in internally film-coated polypropylene woven bags or FFS film bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air.
