1. Endothermic Cooling & Flame Retardant Function
As eco-friendly halogen free flame retardant, ATH aluminum hydroxide flame retardant decomposes and releases crystal water at 200–300℃, absorbing massive heat of polymer matrix to slow thermal decomposition of plastics and rubber, which is the core flame resistant principle of low smoke ATH powder.
2. Oxygen Barrier & Combustion Inhibition
After dehydration, alumina forms compact protective layer on material surface to block oxygen and flammable volatile, effectively interrupt combustion chain reaction and upgrade fire resistance grade of finished products.
3. Low Smoke Non-toxic & Anti-dripping Performance
This aluminum hydroxide flame retardant is completely halogen-free, greatly reduce smoke density and corrosive fume during burning without toxic halogen gas. Its outstanding anti-dripping effect prevents molten dripping of substrate to avoid secondary ignition caused by burning drops, one major advantage of ATH flame retardant.
4. Dual-purpose: Flame Retardant & High White Filler
Low smoke ATH powder acts as both halogen free flame retardant and high-white solid surface filler at the same time, effectively improving physical property of finished goods. Widely applied in solid surface, PVC, wire & cable, rubber and epoxy resin industries.
Our factory supplies bulk high whiteness ATH flame retardant powder, stable quality for artificial marble and plastic raw materials.
