Production Description
Specially developed for producing stretched tapes with following features
Consistent process ability
Easy orientation
Low water carry over
Good mechanical properties
PP Injection molding grade
Introduction registration PP granules polypropylene natural granules
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
Widely used in thermoplastic plastics field, particularly in fiber and filament, thin film extrusion, injection molding process
Main commercial use of the PP of shock resistance is injection molding in automobile, house ware and utensil
Packing: in 25kg polyethylene film bag with outer polypropylene woven bag
Can be palletized
16.5 tons/20'container
Uses: used in all types of thermoplastic processing processes, such as injection molding, extrusion molding, blow molding, root molding, coating, foaming, thermoforming, hot-jet welding and thermal welding
Key Advantages Over Standard PP
Tailored performance for niche applications.
Cost-effective alternative to engineering plastics like ABS or nylon.
Retains PP’s inherent benefits (lightweight, chemical resistance) while addressing weaknesses.
Product application in LED light field
Product application in Switch and Socket
Product application in Toilet-Seat
