Specifications
light calcined kaolin powder :1. Kaolin for Paint.
2. micro powder Kaolin Calcined.
3.Applied in the PVC wire and cable.
calcined kaolin made from kaolin material , (Kaolin divided into from industry: Hard kaolin, Soft kaolin, Sandy clay) , Calcined kaolin clay is calcined to a certain temperature deep-processing products in the calciner , Calcined kaolincalcined during dehydration and the volatiles were removed, Fired at different temperatures with different physical properties of a calcined kaolin .

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 .
