Malvern Minerals Wollastokup® FT Silane Treated Wollastonite
Categories: Ceramic; Oxide; Silicon Oxide; Other Engineering Material; Additive/Filler for Polymer

Material Notes: Wollastokup® is a custom, silane treated calcium metasilicate (wollastonite) which is used as a functional filler in coatings, plastics, rubber and others due in part to its acicular or “toothpick” shape. Within coatings, Wollastokup® improves the durability of the film, improves resistance to weathering, reduces gloss, acts as a flatting and suspending agent and reduces pigment consumption. In plastics, improvements in tensile and flexural strength along with reduction in resin consumption are among the many benefits within plastics. Additionally, improvements in thermal and dimensional stability at elevated temperatures are noted within plastics.
