virgin polypropylene plastic granule homopolymer pp polypropylene price per kg

Product Overview

Description

Polypropylene, as thermoplastic polymer, is widely used in plastic field. Due to different catalyst and polymerization process, the polymers we gain are different in property and application.  

 

PP has many useful properties, but lack of inherent toughness, especially when it below its glass transition temperature, however, by means of adding impact modifier, can enhance its shock resistance.

 

It is widely used in thermoplastic plastics field, particularly in fiber and filament, thin film extrusion, injection molding process and etc. Main commercial use of the PP of shock resistance is injection molding in automobile, house ware and utensil.

 

Its shock resistance, low density, tinting strength and process ability enables it to be ideal material. Moderate shock resistance, resin grade with higher melt flow velocity has higher flowing property, which can be useful in injection molding larger component, such as panels of automobile.
