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 insulation?outer:?PVC plastic product can exponentially increase the volume resistivityAnd inexpensive,?In the?PVC flooring product?can?improve performance and?surface 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 .
