PP Raw Material

Polypropylene random copolymers are also a type of PP Raw Material whose basic structure of the polymer chain is modified by adding different types of monomers. Ethylene is the most commonly used monomer, which causes changes in the physical properties of PP Raw Material. Compared to homopolymerized polypropylene, random copolymers have improved optical properties (increased transparency and reduced cloudiness), improved impact resistance, increased flexibility, lower melting temperatures, and thus lower hot melt temperatures; while remaining essentially the same as homopolymers in terms of chemical stability, water vapor barrier properties, and organoleptic properties (low odor and taste).
