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)
KSS
Anti-dripping

(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
PTFE(TF1645,etc)
