BX FR ST50 Sb2o3 Replacement

Introduction

BX FR ST50 is a crystalline-type polymer phosphate flame retardant generated by reacting the high temperature and high-pressure reaction, and is baked by high temperature, high-pressure airflow powder and effective activation treatment. The performance is very stable. The mixed-use of chlorine or bromine-containing flame retardants significantly increases the synergistic effect with halogen flame retardants, accelerates the capture of free radicals, promotes the interruption of chain reactions in the combustion, and greatly improves the formation of expansion coke layer in high-temperature combustion, It plays the role of heat insulation and isolation of the air, slows down the heat disintegration, and has effective flame retardant effects.

 

Product Features:

  1. BX FR ST50 Environmental-friendly flame retardant effect agent can replace 80-90% Antimony trioxide (SB203 100%).
  2.  No precipitation, especially suitable for PA66, PA6, PBT, PET plastic compounding with glass fiber.
  3. BX FR ST50 is an environmentally friendly flame retardant, that meets the requirements of EU ROHS instructions, Reach SVHC and Sony SS-00259.
