What are the advantages of aluminum hydroxide over other flame retardants?
(1) aluminum hydroxide flame retardant, referred to as ATH, has low price and good flame retardancy!
(2) Aluminum hydroxide flame retardant also has some disadvantages!
1. Poor heat resistance. Dehydration began at 200℃ and was completely dehydrated at 330 ~ 350℃. The resin curing was mostly within the dehydration temperature range of aluminum hydroxide, which led to foaming of the finished synthetic resin.
2. Uneven surface, reduced dielectric properties and low yield. When used at high temperature, it will cause fogging of silica gel, whitening and foaming of products and degradation of dielectric properties.
3.EC≈60~ 100μS/cm, which is easy to absorb moisture.
