Calcium Carbonate Masterbatch for Injection Molding,Website:http://www.best-cap.com, Blow Molding and Extrusion moldingHaichuanda calcium carbonate masterbatch HCD-108 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 double screw extruder. This masterbatch 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 unique special polyolefin 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 masterbatch 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● SpecificationPropertiesTesting ConclusionDensity g/cm31.9-2.1CompatibilityPE , PPMFI g/10min0.6-1.2CarrierPEFilleractivated ultra-fine calcium carbonateAsh content %80Water Contained%≤0.15Melt temperature ℃125Heat Resistance ℃220Addition in Film Sample%10-30ShapegranuleUse for film and micro-filmImprove the print clarity of finished productImprove the opening of finished productSurface of finished product has a good glossIncrease the flow of raw materials in production process, increase production efficiency.Use for injection moldingImprove strong degree, hardness and wear resistance of productAs 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 andstress cracking phenomenon in the use of productsImprove the heat resistance and fire retardancy● 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.
