Aluminum hydroxide accelerant is not limited to dehydration temperature
Among many flame retardants, aluminum hydroxide has been widely used due to its rich structure of water, acid resistance, flame retardant, smoke suppression, good filling effect, no secondary pollution after combustion, and low cost. However, ordinary aluminum hydroxide starts to dehydrate from 200 ° C, and is completely dehydrated from 330 ° C to 350 ° C, while the curing of thermoplastic resins is mostly within the dehydration temperature range of aluminum hydroxide, which leads to foaming in the finished synthetic resin, uneven surface and low yield.
