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.
