      【Scope of application】

      DCHP is a special kind of solid chemical additives. It is mainly use as assistant plasticizer, hot melt adhesive, coat and ink auxiliary agent for PVC, acrylic resin, PS and nitrocellulose; as main plasticizer of Polyvinyl chloride (PVC), acrylic resin, polystyrene, cellulose nitrate.

      DCHP has performance and function can not be replaced by other powder additive.

      【Main performance】

      To increase the liquidity of the resins, increase the amount of plasticization and increase the yield of the unit;

      Improve the product density and tightness;

      Fine light stability and pollution resistant ability used in some special cable and wire;

      To increase the anti-dust adsorption of the product, enhance the surface of the product and make it bright and bright;

      Improve impact strength of the product, the physical and mechanical properties such as tensile strength, tear resistance, strengthen the anti-aging performance of the products, wear resistant, oil resistant, water resistant performance;

      Enhance the colour of the product, make the color of the dye, the printing product more realistic, the color is beautiful, the friction, the senses are good; Improve product demoulding, opening property;

      Can increase the use amount of filling material, reduce cost, improve the quality of reworked material recycling products;

      Can reduce the processing temperature, and accordingly reduce the usage of the original stabilizer.
