Production Description
This engineering thermoplastic (PP) offers the best stiffness-to-density ratio among commodity plastics. Produced via Spheripol or Novolen processes, its thermal expansion coefficient (8-10×10⁻⁵/°C) and moisture absorption (<0.01%) enable dimensional stability in humid environments.
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
