Applications of KSS Potassium Diphenylsulfone Sulfonate 63316-43-8

Used in transparent or translucent halogen-free flame retardant polycarbonate
(PC) material (recommended dosage is 0.1~1%, the actual dosage should be
adjusted according to the formula. In the PC flame retardant formula, because
the addition amount is low, it is very important to disperse evenly, otherwise
the effect will be reduced, and a dispersant can be added appropriately. It can
also be made into high-concentration masterbatch, and then the masterbatch is
pumped together with PC. )

(1) Pure PC halogen-free flame retardant formula (UL-94 V-0/1.6mm):
PC (MFI=6) 99.70%
KSS 0.1%
Anti-dripping 0.2%

(2) PC/ABS (75/25) alloy halogen-free flame retardant (UL 94 V-0/1.6mm):
Only need to use 0.2% HES together, can effectively reduce the amount of RDP,
and at the same time, improve the heat resistance and mechanical properties of
the alloy compound:
PC/ABS(75/25) 90%
Fyrolflex RDP 10%
KSS 0.2%
PTFE(TF1645,etc) 0.2%
