Pigment Red 208, Clariant Red HF2B
Pigment Red 208 belongs to the benzimidazolone red group and is with excellent dielectric properties. Comparable with Clariant HF2B.
P.R.208 is halogen-free and the standard bluish red pigment for PU and flexible PVC coloration.
Pigment blends with compounds such as P.Y.83 or with carbon black are frequently employed to produce shades of brown.
Good dielectric properties make the pigment a suitable candidate for use in PVC cable insulations.
