Chemical name: 3-Phenylsulfonylbenzenesulfonic acid potassium salt
Chemical Structure:
Brand Name: UNFR-KSS
Formula: C12H9KO5S2
CAS Number: 63316-43-8
MW: 336.0
FR-KSS is extremely effective as a flame retardant additive with premium performance in polycarbonate at very low additive levels.
FR-KSS, a non-halogenated product, is said to provide excellent FR effectiveness at fractional loading levels of less than 1 wt% in a PC formulation while maintaining the transparency inherent in the thermoplastic.A white powder, it is the potassium salt of a complex of diphenyl sulfone sulfonate and diphenyl sulfone disulfonate.
For most effective incorporation it is recommended that the additive be initially dispersed into a 10% or more masterbatch and then compounded into the final plastic blend. Dispersion can be achieved effectively with typical polycarbonate processing equipment.
