Sulfonate flame retardants

Introduction of Sulfonate flame retardants

Baoxu Sulfonate flame retardants include KSS FR, HES FR, and FR 2025 three products.

KSS FR is the potassium salt of a complex of diphenyl sulfone sulfonate and diphenyl sulfone sulfonate. HES FR is specifically designed for the most effective translucent and opaque PC. It is not intended for a transparent PC. FR 2025 is the best performance halogen-free flame retardant for Polycarbonate, as an analog to 3M FR-2025.
