PVC gloves differ from vinyl gloves

    Polyvinyl chloride (PVC), English abbreviation of PVC (Polyvinyl chloride), vinyl chloride monomer (vinyl chloride monomer, VCM) such as peroxide, azo compound initiator; Or polymers formed by polymerization of free radical polymerization under the action of light and heat. Vinyl chloride homopolymer and vinyl chloride copolymer are called vinyl chloride resin.

    PVC for amorphous structure of white powder, branched degree is small, relative density 1.4, glass transition temperature of 77 ~ 90 ℃, 170 ℃ or so starts to break down [1], the poor stability to heat and light, in more than 100 ℃ or the sun for a long time, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition, cause discoloration, physical and mechanical properties also fell rapidly, must be added in the practical application of stabilizers in order to improve the stability of heat and light.

    The PVC molecular weight of industrial production is generally within the range of 50,000 ~ 110,000, with a large amount of dispersibility, and the molecular weight increases with the decrease of polymerization temperature. Without fixed melting point, 80 ~ 85 degrees began to soften, 130 to viscoelastic states, and 160 ~ 180 degrees began to change to viscous flow state. Good mechanical properties, tensile strength of 60MPa, impact strength of 5 ~ 10kJ/m2; Excellent dielectric properties.

    PVC used to be the most widely used plastic in the world. In building materials, industrial products, daily necessities, plastic flooring, floor tile, artificial leather, pipe, wire and cable, packaging film, bottle, foaming materials, sealing materials, fiber, etc, are widely used.
