PP Flame Retardant Masterbatch

Introduction

FR-CPP-4 consists of environment friendly flame retardant system of bromine, phosphorus and nitrogen, comply with ROHS requirement. It is not only relies on gas and condensed phases to the dual flame retardant but also takes away heat by melt dripping through the catalytic effect to get flame retardant effect. Advantages: high effective, low smoke, no mold corrosion, high smoothness, low halogen and high cost performance.

Application

Mainly used in PP injection and extrusion, such as: PP receptacle, PP blower, except that, it can be used in PP hollow plate, cast film, non woven fabric, panel, clapboard, enclosure of household appliance, connecter, outdoor flame retardant seat etc. Products.
