Product Description

Product Description

Polypropylene random copolymer is also a kind of polypropylene, and the basi   c structure of its polymer chain is modified by adding different kinds of monomer molecules. Ethylene is the most commonly used monomer, which causes changes in the physical properties of polypropylene. Compared with PP homopolymers, random copolymers have improved optical properties (increased transparency and reduced haze), improved impact resistance, increased flexibility, and reduced melting temperature, thus reducing hot melt temperature. At the same time, the chemical stability, water vapor isolation properties and organ sensory properties (low odor and taste) are basically the same as the homopolymer. Used in blow molding, injection molding, extrusion, film and sheet extrusion processing fields, authors with water pipes, food packaging materials, pharmaceutical packaging materials and daily consumer goods.
