Sinopec PP random copolymer is a copolymer resulting from the random distribution of ethylene in propylene chain segment.
What is the Polypropylene Random Copolymer?
Sinopec PP random copolymer is a copolymer resulting from the random distribution of ethylene in propylene chain segment. The resin has good transparence, glossiness, heat resistance and processability.
Application of the product
PP random copolymer is widely used in the production of medical appliances with high transparence, such as medical syringes, medical infusion bottles,medical centrifuge tubes and sample tubes. It is used in the production of food containers, stationery, packaging materials and houseware.
