Haichuanda calcium carbonate filling master batch is a Pe based master batch containing activated ultra-fine calcium carbonate with dispersant, plasticizer, antidegradants kinds of auxiliary agent. After repeated mixing and blending made of oval granule by extruder. It is applicable to all types of polyolefin resin filling and modification, and can significantly improve production efficiency and reduce power consumption and lower raw material costs. At present the products are widely used in plastic film and extrusion, injection molding, blow molding product. The company’s advanced production process developed a formula and a unique special polyefin film master batch, this product formula designed to not only strengthen the interface between the filler and the resin even together, but also take into account the master batch and resin compatibility between. So that the master batch have features of large quantity loading, high strength, good dispersion and can be many ways to improve the performance of plastic products. The master batch low prices and energy-saving features that can significantly reduce the cost of finished products Use for film and micro-film Improve the print clarity of finished product Improve the opening of finished product Surface of finished product has a good gloss Increase the flow of raw materials in production process, increase production efficiency. Use for injection molding Improve strong degree, hardness and wear resistance of product As the master batch have high thermal conductivity, workpiece temperature balance is good in molding process, which can significantly reduce the shrinkage, collapse pits and deflection deformation phenomenon of workpices, improve dimensional stability, reduces the inner stress and stress cracking phenomenon in the use of products Improve the heat resistance and fire retardancy Specification

As the master batch have high thermal conductivity and good fluidity, molding process workpice cooling fast (compared with the pure resin) which can shorten the molding cycle and improve production efficiency.
The good fluidity of master batch can reduce the injection molding temperature and pressure, saving energy.
Add to this master batch, does not affect the original electrical insulsion and alkali resistance.
◆Use for hollow blow molding, extrusion molding
Improve anti-bending strength of the finished products
Reduce shringkage and improve dimensional stability of the finished products, reduce shrinkage distortion of the finished products, and the phenomenon of collapse pits.
Improve the thermal properties and heat distortion temperature, flame retardancy, thermal conductivity and lower thermal expansion coefficient of the finished products.
Improve the thermal conductivity and mobility in the production process, reduce product cycle times, improve production efficiency.
If the finished product is white, can improve its whiteness, reduce the use of white master batch.
