Aluminium Trihydrate (ATH) is on of the common fillers used in plastics, rubber, FRP, SMC, DMC moulding and other polymers only alumina trihydrate has flame retarding and smoke suppressing properties as well as being an economical resin extender.
Aluminium Trihydrate (ATH) is used in polyester resins. However with increased attention being given to smoke & toxic fume emissions, Aluminium Trihydrate (ATH) has found large volume application in vinyl as a low smoke, non toxic replacement for antimony and in polyurethane, latex, neoprene foam system, rubber, wire & cable insulation, vinyl walls & flooring coverings and epoxies. Alumina trihydrate acts as a flame retardant and smoke suppressor because of its thermodynamic properties. Its endothermic dehydration cools the plastic & rubber parts and dilute with water vapour those combustible gases that do escape.
Aluminium Trihydrate (ATH) widely use in paper Industries as a whitening agent in place of titanium dioxide.
