Why does the P-N-based intumescent halogen-free flame retardant lose its flame retardant effect after adding filler or other substances?

2021-09-18

In order to reduce the cost, many people added some fillers such as calcium carbonate, barium sulfate, talc, magnesium hydroxide, etc. to the P-N-based expanded Halogen-Free Flame Retardant, and found that the Flame Retardant effect was lost. It is because the addition of the above filler changes the esterification reaction process, and the acid source partially reacts with the above filler, and the above filler destroys the formation of the carbon layer on the surface of the material, resulting in failure of the mechanism.

By the same token, adding some carbon black and toner will also cause the flame retardant effect to be lost. Therefore, some recycled PP materials may be partially filled with PP and added to the new material, which causes the system to be phased into the above-mentioned filling, which makes the system lose its flame retardant effect.

Novista Group supplies equivalent of FP-2100JC, FP-2200S, FP-2500S, Exolit OP1230, OP930, OP1312, OP1314 to global market.
