Calcined kaolin is made from kaolin material. Kaolin divided into from industry: Hard kaolin, Soft kaolin, Sandy clay. Calcined Calcined kaolin clay is calcined to a certain temperature deep-processing products in the calcined. Calcined kaolin is calcined during dehydration and

the volatile were removed. Fired at different temperatures with different physical properties.

Usage:
In paper industry: Calcined kaolin are widely used paper coatings and fillers
In rubber industry: mainly use as a Reinforcing agent and filler used, rubber product can be improved Solvent resistance and abrasion resistance
In plastics and cable industry: Plastics can effectively improve the strength and modulus of resistance. Without reducing the ductility and impact strength. Can also improve the performance of products.
In polyvinyl chloride (PVC) cable insulation outer: PVC plastic product can exponentially increase the volume resistivity And inexpensive, In the PVC flooring product can improve performance and surface gloss
In nylon: To improve its deflection and tensile strength,In film and tape use as an Anti-clogging agent, In plastic sheeting to use as adsorbent, etc.

Size and used:

Size of sand: 8-16,16-30,30-60,30-80,60-80,80-120 (mesh): Used for investment casting.
Size of powder: -200mesh,-270mesh,-325mesh:  Used for investment casting and refractories.
Size of particles: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-15mm, 0-5mm, 0-50mm: Used for refractories.
