PVC cable is made of polyvinyl chloride resin, a stabilizer, a plasticizer, a filler, a lubricant, an antioxidant, a coloring agent composition. Salt of lead salt stabilizer primary stabilizer, generally used in conjunction with a variety of stabilizers, flame retardant PVC use synergies to improve thermal stability. Tribasic of lead sulfate, dibasic lead phosphite nature and use, can both heat and light stability. High temperature cables heat resistant primary stabilizer of good dibasic acid lead. Cable as soft products, a large number of plasticizers, so generally do not pay attention when formulation lubricants retardant PVC prices, will use some low-grade lubricant, these low-grade lubricant of low melting point, out late a lot of volatile components out of fire retardant PVC can not be excluded at this time, had been wrapped folder molten material forward, since the gas light weight, will escape to the surface as possible, occupy a certain space, and the material is forcibly transported together, out of the die after it immediately goes into the air, but the cable but left little trace. Shandong Antai New Material Technology Co., Ltd. Main PVC cable, welcomed the new and old customers to buy. My company provides products flame test analysis. Cable surface roughness surface roughness are two problems, one is pimple, one is the pitting. Pimple mainly by some uneven dispersion powder mixed aggregates plastics extrusion process can not, be plasticized PVC coated material extruded from the die together PVC flame retardant chemical composition, and in cable compound formation. Fish-eye and did not fully absorb the plasticizer PVC resin particles mentioned above, can also cause pimple phenomenon, but generally small. Shandong Antai New Material Technology Co., Ltd.
