What Is Ppr

The chemical name of ppr is random copolymer polypropylene

Polypropylene random copolymer [1] is also a kind of polypropylene. The basic structure of its polymer chain is modified by adding different kinds of monomers. Ethylene is the most commonly used monomer, which causes changes in the physical properties of polypropylene. Compared with PP homopolymer, the random copolymer has improved the optical properties (increased transparency and reduced haze), improved the impact resistance, increased flexibility, reduced the melting temperature, and thus reduced the hot fusion temperature; At the same time, it is basically the same as homopolymer in terms of chemical stability, water vapor isolation performance and organ sensory performance (low odor and taste). It is used in the fields of blow molding, injection molding, extrusion molding, film and sheet extrusion processing. It is used for water pipes, food packaging materials, medical packaging materials and daily consumer goods.
