Product Application

RK-152 is one kind halogen-free environment friendly polyolefin flame retardant based on nitrogen and phosphorus as its mean flame retardant element. It is mainly designed for various kinds of flame retardant polypropylene products and other flame retardant polyolefin products.

The flame retardant property of homopolymerize and copolymerization PP which is added RK-152 can be reach UL 94-V0(0.75mm). The homopolymerize and copolymerization PP which is added RK-152 has passed 70℃×168 hours submerging test and GWIT 750℃and GWFI 960℃Glow-wire test. And it is not limited by RoHS (Restriction of Hazardous Substances).

Flame retardant products which use RK-152 have the advantage of little density, low fuming quantity, little mould corrosion.

Because the RK-152 has Hydrophobic ability, when it is used into polypropylene will not occur neatly phenomenon.
