Product Description




JLW supply multiple specifications of aluminum hydroxide powder and provide on-demand customization according to customer needs. All the properties such as whiteness, particle size can be customized. Contact us today for tailored support!
Aluminum hydroxide is the most widely used inorganic flame retardant additive, is a kind of ideal fire retardant filler for plastic and organic polymer. It is non-hygroscopic with customizable grain size and non-toxic with stable whiteness at curing. Thus it has functions of filling, fire-retarding and smoke abatement. Aluminum hydroxide, as a flame retardant, not only can be flame retardant, but also can prevent smoking, produce no droplets, and produce no toxic gases. Therefore, it has been widely used and its usage is increasing year by year.
Aluminum hydroxide micro powder is eco-friendly halogen free flame retardant additive, which is a white loose powder with high whiteness and low bulk density. It is stable at room temperature and undergoes thermal decomposition and dehydration to produce alumina.
This product is different from other flame retardant materials in that it does not produce toxic or corrosive gases during pyrolysis, and absorbs heat and releases water vapor during pyrolysis, making the product flame retardant and self extinguishing. Therefore, adding this product to composite materials such as plastic and rubber not only enhances the flame retardant and smoke eliminating effect of the product, but also enhances its resistance to electric leakage, arc resistance, and wear resistance.
