CAS :
nature : PVC. By polymerization of vinyl chloride by the polymers. A thermoplastic. Industrial products are white or pale yellow powder. The density of about 1.4. Chlorine content in 56 ~ 58%. Low molecular weight soluble in ketones, esters and chlorinated solvents. Polymer volume is hard to dissolve. With excellent chemical corrosion resistance, thermal stability and poor light fastness, 100 ° C above or prolonged sun exposure from the beginning decomposition of hydrogen chloride, manufacturing plastics needs to be stabilized. Electric insulation fine, not burn. The system for plastics, coatings and other synthetic fibers. According to the increase in the number of plasticizer can be obtained soft and rigid plastics. The former can be used to the system transparent thin films (such as raincoats, table cloth, packing material, plastic sheeting, etc.), leather, foam and wire sets layer. The latter system can be used for sheet metal, piping, valves and doors and windows. The latter system can be used for sheet metal, piping, valves and doors and windows. With suspension polymerization, in powdered resin. Emulsion polymerization, in a paste resin. The system can be used for soft or hard plastic. Various raw materials in Z-ends.5 Kneading Machine, and then mix into the calendar of the 165 ~ 175 ° C plastination uniform mixing, and then-calendar, pyramid processes can be made of rigid PVC sheet, used for building materials.
