The advantages of adding calcium sulfate whiskers to downstream products are in comparison to general inorganic filler fibers. Currently, plastics, rubbers, and many chemical products use fillers to reduce costs or improve relevant properties: organic or inorganic fiber bases are used for reinforcement. Among them, the main inorganic fillers include: wollastonite, silica, and calcium carbonate powder; the main reinforcing fibers include: glass fibers, carbon fibers, wollastonite fibers, and polyester fibers.

The thickness of one hundred calcium sulfate whiskers is equivalent to that of a single glass fiber. Due to the extremely fine nature and near-perfect crystallization of the whiskers, which do not allow for larger defects that could weaken the crystal structure, they possess extremely high mechanical strength, equivalent to the forces between adjacent atoms. Calcium sulfate whiskers combine the advantages of inorganic fillers and reinforcing fibers, and when applied in products, they exhibit excellent overall performance.
