Epoxy Plasticizer
LOW SMOKE SUPPRESSANT & FIRE RETARDENTS
Aluminum trihydrate is the most consumable and applicable inorganic additive flame retardant that does not only resist firing but also prevents from smoke, dropping or toxic gas. Alumina trihydrate contains 3 molecules of water; upon heating above 220°C up decomposes into aluminium oxide & water. This irreversible, endothermic reaction process makes alumina trihydrate an effective flame retardant.
Widely used as fire retardant filler in applications like polymer composites, cable compounds, artificial marble, FRP, SMC, DMC moulding, synthetic rubber, coating and construction materials.
