product property:
pvc resin: the thermoplastic high-molecular polymer made by the suspension polymerization of vinyl chloride monomer. the molecular formula :- (ch2 - chcl) n - (n: degree of polymerization, n= 590 ~ 1500). it is the most widely raw material used in plastic production. it has good chemical stability, corrosion resistance and water resistance. it can be dissolved in acetone, hydrochloric ether, ester and some alcohol. it can offer good solubility, good electrical insulation, thermo plasticity and membrane forming capacity
product type:
sg-2¡¢sg-3¡¢sg-4¡¢sg-5¡¢sg-6¡¢sg-7¡¢sg-8 ,etc£¬more production on sg-3¡¢sg-5¡¢sg-7¡¢sg-8.
product application:
automobile interiors, family decorative materials, advertising light box, shoe soles, pvc pipes, pvc profiles, pvc sheet and plate, rolling film, inflatable toys, outdoor products, pvc wire and cable, pvc artificial leather, wood and plastic floor, corrugated board, etc.
pvc resin sg5 applications:
it is widely used in the production of water pipe, chemical pipe, plastic windows and doors, packing film, plastic carpet, plastic ceiling, sanitary fitting, leatheroid, plastic wallpaper etc.
