Shandong Weifang PVC flame _ Advanced Technology (certified) _PVC retardant provided by Aetna New Material Technology Co., Ltd., Shandong. Shandong Antai New Material Technology Co., Ltd. (www.antaitech.com) is specialized in the "fireproof material" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: the Wu Hu. PVC cable is made of polyvinyl chloride resin, a stabilizer, a plasticizer, fillers, lubricants, antioxidants, coloring agent composition. Fillers: Cable compound by adding fillers can improve the electrical insulation properties, heat resistance and cost Weifang PVC flame retardant, but too much will cause the amount of formability and cable performance. To improve the insulation, the insulation level cable compound subjects chosen calcined clay (electricity use level) as a filler. Sheath (layer) grade cable can be used calcium carbonate as a filler. Shandong Antai New Material Technology Co., welcomed the new and old customers to buy. Two-stage extruder consists of two parts, with the first order for high-speed twin-screw mixer, second-order low-speed single-screw extruder, both vertically arranged orthogonally Shandong retardant PVC, constitute a double order composite unit; the same twin-screw and single-screw combination of complementary advantages. Twin-screw conveyor mandatory, efficient plastics mixing and shear dispersion, inorganic flame retardant PVC reflux head back pressure manufacturers to avoid the high shear overheating; high-pressure single-screw extruder, but low speed shear, also avoid overheating contradictions. Particularly suitable for processing PVC and other heat-sensitive materials. Twin screw processing temperature of 150 ~ 185 ℃, single screw temperature 130 ~ 165 ℃. Using air grinding grain fervent way, pellets after cyclone shaker into the hopper.
