How should calcium carbonate masterbatch be selected and used in injection molding?
Calcium carbonate filler masterbatch has the characteristics of good dispersion plasticization, at the same time, enhance the rigidity of the products and increase the weight of the products, reduce the shrinkage of the products and the deformation caused by shrinkage, strong anti-oxidation and aging resistance, high filler volume, etc., enhance the hardness, rigidity, compression and abrasion resistance of the filled products, and reduce the shrinkage of the products and the deformation caused by shrinkage, etc., which greatly reduces the cost of the enterprise's production, and obtains a certain degree of economic benefits.
Calcium carbonate filler masterbatch has filler modification, can improve the performance of plastic products, reduce the cost of products, improve production efficiency, and obtain good economic benefits.
Calcium carbonate masterbatch can be used in ABS, PP, PE, EVA, HIPS, PC and other plastic applications, can be used as injection molding, blowing bottles, plastic knives and forks, fast food containers, tubes, sheets, hollow boards, electrical shells, packing tape, woven bags, garbage bags, shopping bags, non-woven fabrics, colorful strips of fabrics, cast film and so on.
Calcium carbonate masterbatch is generally composed of carrier resin, calcium carbonate powder, dispersant, coupling agent, lubricant, antistatic agent, antioxidant and so on.
Calcium carbonate is the core of masterbatch, which determines the basic performance of masterbatch. The content of calcium carbonate powder in calcium carbonate masterbatch is generally about 80% by twin-screw extruder and 88% by continuous refiner.
