What is the calcium plastic box introduced by the Corrugated Plastic Dividers manufacturer? The calcium plastic box is composed of polyethylene or polypropylene raw materials and calcium carbonate powder, and then add some lubricants zinc stearate, barium stearate, antioxidant CA and DLTP fillers, and finally through high pressure and high temperature mixing and rolling Compressed, high strength, adjustable hardness, good compression resistance, the reasons are as follows:
Determined by the rigidity of polypropylene and polyethylene. Both are crystalline resins, and the rigidity of the resin is generally related to the degree of crystallinity. The higher the resin density, the higher the rigidity and the hardness of the molded product can be randomly adjusted during processing.
The chemical properties of polypropylene and polyethylene are stable. They can resist all organic chemicals and solvents, have good acid resistance, alkali resistance, and excellent corrosion resistance. Coupled with the water resistance and moisture resistance of plastics, they are not affected by the external environment at all.
Various stabilizers can be added during the production process of calcium plastic board to strengthen and prevent aging. The formula for adding stabilizers can be divided into two types: formulas for food containers and industrial formulas used under harsh conditions at high temperatures. Manufacturers can make adjustments according to their needs during production, including product rigidity, viscosity, heat resistance, impact resistance, and transparency, Shrinkage, degree of warpage, etc.
