Alumina Trihydrate or ATH is the leading flame retardant used worldwide for plastics and rubber materials, functioning as a filler and offering non-toxic, smoke suppressant properties. Low resin demand, consistent quality and relative cost-performance benefits make CHENXU an ideal choice for uses such as SMC, BMC, thermoplastic profiles, paints & coatings and adhesives. Several grades of CHENXU are available, differentiated by particle size, to meet specific performance requirements. Alumina Trihydrate is used as a filler for epoxy, urethane, or polyester resins, where fire retardant properties are required.
