1、 Product introduction
Homopoly PP special environment-friendly flame retardant is a high-efficiency and environment-friendly flame
retardant containing phosphorus and bromine. This product can reach UL 94 V-2 level by adding a small
amount (1.2%) to homopoly pp. it has good self extinguishing effect, no precipitation, no frost, and there is no need to add additives such as antimony trioxide and antioxidant. The formed product has good surface gloss, good thermal stability, water resistance, non-toxic, etc.
As an additive flame retardant, this product is applied to homopolymer flame retardant PP with flame retardant requirements of UL 94 V-2. Fillers (such as talc powder, barium sulfate, glass fiber, etc.) can be added appropriately.
It is not suitable for polypropylene with calcium powder. The modification of silane coupling agent will reduce the flame retardant effect.

3、 Conclusion
● ht-115 special environment-friendly flame retardant for homopolymer PP has the characteristics of low addition, good mechanical properties of flame-retardant modified PP and high cost performance.
● compared with similar products in the current market, ht-115 homopoly PP special environmental flame retardant can be filled with talc powder, barium sulfate and other fillers, and glass fiber can be added appropriately without affecting the flame retardant effect.
● compared with octabromoether and decabromodiphenylethane, ht-115 homopoly PP special environmental flame retardant has less addition and low smoke density of flame retardant products.
