Selection Of Flame Retardant In Flame Retardant Masterbatch

Jun 23, 2020



Selection of flame retardant in flame retardant masterbatch

Flame retardant masterbatch is also called fire retardant masterbatch, and it is the most excellent flame retardant product in the plastics industry today. Its dispersibility, fluidity, compatibility, thermal stability and weather resistance in resin are much higher than ordinary flame retardants. It can improve the dispersion of flame retardant in resin, reduce the amount of flame retardant added, reduce the processing difficulty and processing cost, at the same time can reduce the impact of the addition of flame retardant on the mechanical properties of the resin, improve the workshop working environment. The selection of flame retardants in flame retardant masterbatches also contains a lot of knowledge and skills.

  The flame retardants commonly used in plastics are as follows:

 Inorganic flame retardants, aluminum hydroxide, magnesium hydroxide, antimony trioxide, etc.;

 Organic flame retardant, decabromodiphenyl ether (DBDPO) is an additive flame retardant with high bromine content, which has a wide range of applications and can be used for PE/PP/PS/PETABS, etc. The disadvantage is weather resistance Poor. In addition, there are octabromodiphenyl ether (BDDP)/hexabromobiphenyl ether, etc.;

 Other flame retardants, chlorinated paraffin, red phosphorus, etc.


Tips: The selection of flame retardants should pay attention to the following matters:

   1. Different flame retardants are used together to play a synergistic role;

   2. The flame retardant does not chemically react with other additives in the masterbatch                  and has good compatibility with the resin;

   3. Excellent thermal stability.u=1815754997,4125360072&fm=26&gp=0
