(Summary description)
Among the many flame retardants, aluminum hydroxide is widely used due to its abundant structural water, acid resistance, flame retardancy, smoke suppression, good filling effect, no secondary pollution after combustion, and low cost. However, ordinary aluminum hydroxide starts to be dehydrated at 200°C, and is completely dehydrated at 330°C to 350°C. The curing of thermoplastic resins is mostly within the dehydration temperature range of aluminum hydroxide, which results in foaming in the synthetic resin product and uneven surface. The rate is low.

1% dehydration temperature is above 350℃, 500℃ dehydration reaches the peak value, EC<50μS/cm, strong dielectric property, solves the problem of product defects and reduced dielectric properties caused by low dehydration temperature of aluminum hydroxide, acid and alkali resistance Strong sex.

The flame retardancy is slightly lower than that of aluminum hydroxide, and more needs to be added to achieve the same flame retardancy. But its biggest feature is high heat resistance, thermal conductivity, acid and alkali resistance, and the production of high heat resistance functional materials can increase the added value of the product. The high heat-resistant boehmite flame retardant solves the problem of product defects and reduced dielectric properties caused by low dehydration temperature of aluminum hydroxide. (jwl)
