Polyvinyl chloride, English for short (Polyvinyl chloride), is an initiator of vinyl chloride monomer (VCM) in peroxides, Azov compounds, etc. Or under the action of light and heat according to the mechanism of free radical polymerization Polymerized polymer. Vinyl chloride homo-polymers and vinyl chloride co-polymers are collectively referred to as vinyl chloride resins.
PVC is an amorphous white powder with a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77 ~ 90 ° C, and decomposition at about 170 ° C . Poor stability to light and heat, above 100 ° C or After prolonged sunlight exposure, it will decompose to produce hydrogen chloride, and further automatically catalyzes decomposition, causing discoloration, and physical and mechanical properties are also rapidly reduced. In practical applications, stabilizers must be added to improve the stability to heat and light.
The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000. It has a large perversity, and the molecular weight increases with the decrease of the polymerization temperature. Without a fixed melting point, it begins to soften at 80 to 85 ° C and becomes viscosity at 130 ° C. , 160 ~ 180 ℃ began to change to viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties.
PVC was once the world's largest general-purpose plastic, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
