Property：
In normal ambient, PVC resin is amorphous white powder with density of 1.35-145g/cm3 and apparent density of 0.45-0.65g/cm3, not solved in water, gasoline, alcohol, but can solved in organic solvent such as ether, ketones, chloridized aliphatic hydrocarbons and aromatic hydrocarbons with many good functions such as antiflaming, high resistant on chemicals, high mechanical strengths and excellent electric insulativity.

Application:

(1) PVC paste resin is mainly used in the field of soft materials, and can be applied to processing techniques such as coating, dipping, slush molding, dripping, spraying, foaming, etc.

(2) PVC paste resin is widely used in artificial leather, decorative materials, floor leather, wall paper, automotive interiors, light conveyor belts and mine flame-retardant belts, sports floors, paints, adhesives, toys, disposable medical gloves, household items, battery separators, electrical instruments and electrical tools, and many other materials and products.
