Specifications
high quality gypsum whisker (calcium sulphate)

1.Its raw material is by-product of titanium dioxide production
2.Recycling, lowest price, super quality
3.OEM Provided

Property:

1. Calcium sulphate whisker, named Gypsum whisker, is fibrous single-crystalloid, white loose acicular substance, with integrated structure. Slightly soluble with water, it assumes neutrality in water-soluble fluid.

2. It has 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. Compared with other inorganic whisker, calcium sulphate is a environmental-friendly stuff with least toxicity.

Application:

1.  It is a widely use industrial material, which can be used as cement retarder, medical food additive, building gypsum, filter in paper and paint filter.

2. Gypsum whisker add in composite material can also improve product stability, heat resistance, dielectric property and reduce the shrinkage and water absorption rate.

3.As a substitute of asbestos for friction material, building material, thermal /cool insulation material.

     Calcium sulphate whisker can be divided into three kinds: dihydrous calcium sulphate whisker, hemihydrate CaSO4 Whisker, anhydrous calcium sulfate whisker.
