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.
