Copolymer Polypropylene Granule

The granule formed by the polymerization of polypropylene with ethylene comonomer is called a copolymer polypropylene granule. Polypropylene copolymer has a higher impact resistance than polypropylene homopolymer. By adjusting the amount of ethylene added to the polymer structure, the morphology of the copolymer, the type of crystallization, and the molecular weight can be controlled to a good extent to increase impact resistance. However, it should be noted that increasing the impact resistance of polypropylene will result in a decrease in the hardness and stiffness of the polymer. Polypropylene copolymer itself is divided into two parts: block copolymer and random copolymer. The copolymer has a high processing capability, so it is mostly used in industries such as medical devices and sterile medical supplies such as bands, gauze, etc. Asan Form Kimia is one of the prominent suppliers and exporters of recycled copolymer polypropylene granules in Iran.
