Production Description
This synthetic polymer, chemically classified as polypropene (PP), is manufactured through propylene monomer chain polymerization. Characterized by partial crystallinity and non-polar molecular structure, PP combines polyethylene-like properties with improved temperature resistance (up to 160°C) and mechanical strength. Its opaque white form demonstrates remarkable chemical inertness across industrial applications.
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
