Production Description
PP resin, created through Ziegler-Natta catalyzed polymerization, offers unique combinations of stiffness and toughness. The thermoplastic's non-polar crystalline domains provide oil/chemical resistance while maintaining processability between 160-170°C. Its higher service temperature (vs. PE) and FDA-compliance make it preferred for packaging and automotive components.
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
