What is EcoFlame S-336?
It refers to potassium 3-(phenylsulfonyl)benzenesulfonate, and it is a potassium salt of diphenyl sulfone sulfonate. More exactly, it is the potassium salt of a complex of diphenyl sulfone sulfonate and diphenyl sulfone disulfonate. So, it is also known as potassium diphenylsulfone sulfonate.
What is it used for?
As a halogen free flame retardant, our product is able to provide remarkable flame retardant performance for polycarbonate at a very low loading level, typically less than 1% by weight in a PC formulation. Moreover, the PC thermoplastics will keep its transparent look as always.
How to use it?
In order to get the best result, EcoFlame S-336 should be dispersed into masterbatches with 10% or higher concentration at first, and then compounded into final product, namely flame retardant plastics. In addition, the dispersion process can be conducted by typical PC processing machines.
