Self-Extinguishing Grade(Non-HBCD)


A.Characteristic

Pre-expansion:

  • Comment steam pressure
  • Shorter intermediate aging time in silo
  • Wide processing window(suitable for both low and high density application)

Moulding:

  • Excellent fusion and surface finish
  • Versatile-suitable for wide range of products
