Calcium sulfate whisker
Calcium sulfate whisker is a new type of fibrous sub-nanomaterial grown in the form of single crystal, with uniform cross-section, complete shape and perfect internal structure. Calcium sulfate whisker has high strength, high modulus, high toughness, high insulation, wear resistance, high temperature resistance, acid and alkali resistance, corrosion resistance, good infrared reflectivity, easy surface treatment, easy to compound with polymer, non-toxic and many other excellent physical and chemical properties. The company prepared by a special process of anhydrous calcium sulfate whiskers, the basic performance indicators are as follows:
