calcite; PE (Polyethylene), PVC (polyvinyl chloride) and PP (polypropylene) derived producing plastic pipes with a high filler content and is used by manufacturers. In the manufacture of pipes and profiles according to the manufacturer's machine structure Coated and Uncoated possible to use two kinds of calcite.  
Benefits of Esen Calcite : 
• PE, PP or PVC, provides the use of a small amount. 
• Stearic acid coated calcite, acts on a surface roughness of pipe 
• Quieter influence the production tubing. 
• Production costs of the pipe is reduced.
• Calcite is stable intricacies produced in the machine efficiency is increased.
