Production Description
Polypropylene (PP) is a semi crystalline thermoplastic. It has high
impact resistance, strong mechanical properties, and resistance to
various organic solvents and acid-base corrosion. It has a wide
range of applications in the industry and is one of the common
polymer materials.
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
