Main using :
1)In paper industry: Calcined kaolin are widely used paper coatings and fillers
2)In rubber industry: mainly use as a Reinforcing agent and filler used ,rubber product can be improved Solvent resistance and abrasion resistance
3) 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.
4). In polyvinyl chloride(PVC)cable insulationouter: PVC plastic product can exponentially increase the volume resistivityAnd inexpensive,In thePVC flooring productcanimprove performance andsurface gloss
5) 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 .
