Calcium sulphate whisker, named Gypsum whisker, is calcium sulphate fibrous single-crystalloid, white loose acicular substance, with integrated structure, rounded figure, given cross section, stable size. Its average ratio is 50~80. Slightly soluble with water, it assumes neutrality in water-soluble fluid. It has the density of granular filling, the ratio of short fibrous filling, the characters of heat-resistance, acid-alkli resistance, chemic erode resistance, well tenacity, excellent insulation, high intensity, easily to be external disposed, meanwhile, it concurrently dissolves well with resin, plastic, rubber, and it is well-proportioned spreading, the PH value is near neutrality. It also has good intensifying function and flame retardance Compared with other inorganic whisker, calcium sulphate is a environmental-friendly stuff with least toxicity. Calcium sulphate whisker can be divided into three kinds: dihydrous calcium sulphate whisker, hemihydrate CaSO4 Whisker, anhydrous calcium sulfate whisker.
Application: Plastics Additive, Heat Insulation materials and other fields due to its better qualitythan other similar products. As a kind of friction materials, it has been replaced Asbestus, and showed much more superior quality.
