50 % replace antimony trioxide flame retardant
This product can replace 40-60% antimony trioxide（Sb203≥99.5%）， Especially suitable for flame retardant modification of ABS, PBT, pet, PP, PA, HIPS, and other plastics.
Polymeric flame retardant
A kind of crystalline polyphosphate flame retardant produced by high temperature and high-pressure reaction in a reactor， which is baked at high temperature, ground by high-pressure airflow, and effectively activated, the performance is very stable when the product is mixed with chlorine or bromine-containing flame retardants, the synergistic effect with halogen flame retardants is significantly increased, the capture of free radicals is accelerated, and the chain reaction in combustion is interrupted. At the same time, the formation of an expansible coke layer in high-temperature combustion is greatly improved, the function of heat insulation and air isolation is played, and the thermal decomposition reaction is slowed down, so as to play an effective flame retardant effect
Product Features
1. Environmentally friendly flame retardant synergist can replace 40-60% antimony trioxide (sb203 ≥ 99.5%). Due to its high whiteness (> 98%), high thermal decomposition temperature (> 380 ℃), good dispersion, no color change, and no precipitation, it is especially suitable for ABS, PBT, pet, PP, PA, Flame retardant modification of hips and other plastics
2. It is an environmentally friendly flame retardant, The products meet the requirements of the EU ROHS directive, REACH SVHC, and SONY SS-00259

- Special instructions for product use：
1.The purity of replaced Sb2O3 should be more than 99.5%.
2.According to the use of a large number of customers, we suggest adding 0.5% – 1% on the basis of replacing Sb2O3 in the same amount, which is more conducive to the high stability of the product
- Packaging, storage and transportation：
White powder, 25kg per package, in lined paper plastic composite film bags, stored and transported as non dangerous goods. In addition, in order to protect intellectual property rights, the company’s technology patents are involved,Other substances are not listed separately。
