Malvern Minerals Trikup® PT Silane Treated Aluminum Hydroxide
Categories: Ceramic; Oxide; Aluminum Oxide; Other Engineering Material; Additive/Filler for Polymer

Material Notes: Trikup® is a custom, silane treated alumina trihydrate or aluminum hydroxide. ATH is the largest volume flame retardant in the world. Trikup® adds additional functionality through the use of epoxy, amino, vinyl and other silanes chosen to react with specific resin systems. Trikup® contributes brightness, opacity, gloss and smoothness to coatings. Additionally, Trikup® is exceptional for arc track resistance in PCBs and other composites. Additional fields include high power bushings and insulators. Typical Applications: Coatings, Silicone Rubber, Plastics, Wire & Cable, Adhesives, SMC/BMC, Composites
