Is one of the Common fillers used in Plastics, Rubber, FRP, SMC, DMC moulding and other polymers only ATH has flame retarding and smoke suppressing properties as well as being an economical resin extender. Crystal Fine Chem is one of the leading processor of ATH.
ATH is used in polyester resins. However with increased attention being given to smoke & toxic fume emissions, 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. The latter is probably the main phenomenon associated with smoke suppression other excellent performance include electrical and track resistance.
Alumina Trihydrate widely use in Paper Industries as a whitening agent in place of titanium dioxide.
ATH is also use in Paints Industries. ATH can replace upto 25% of the Titanium dioxide pigment & therefore is an economical extender reducing production cost.
