Production Description
Polypropen, the second highest volume plastic globally, is characterized by its balance of processability and performance. The semi-rigid material's β-crystalline phase enhances impact strength while maintaining chemical resistance to acids/bases. Typical melt flow indices (MFI 0.5-25) allow diverse processing methods from extrusion to injection molding.
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
