HCR Masterbatch

  • ​Slight refreshing after prolonged storage.
  • Easy processing.
  • No post curing.
  • Good compromise between mechanical properties.
  • Outstanding dielectric properties.
  • Outstanding release on non-tin platted copper with the use of dichloro-2,4 benzoyl peroxide and heat curing in a molten salt bath.

BLUESIL FRC 8470 U gives exceptional fire performances after heat curing. When exposed to a flame, it transforms itself into an insulating and ceramic material capable of withstanding thermal stress and mechanical impact. This explains its outstanding performances during the test conditions described in the following standards:

  • NFC 32070 C1 CR1
  • BS 6387 CWZ
  • DIN 4102-12
  • EN 50200

​BLUESIL FRC 8470 U is the ideal material for the insulation of fire-resistant safety cables.

BLUESIL FRC 8470 U, although especially recommended for cabling, can be processed using traditional techniques and on equipment widely found in the rubber industry.
