Product Desciption
Suspension Grade PVC Resin Sg5 for PVC Pipes and Fittings
PVC Resin is a white powder with amorphous structure, with a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90 ° C, and decomposition at around 170 ° C. The stability to light and heat is poor, above 100 ° C or over a long period of time. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration, and physical and mechanical properties are also rapidly declining. In practical applications, stabilizers must be added to improve the stability to heat and light.
Industrial production of PVC molecular weight is generally in the range of 50,000 to 110,000, with greater polydispersity, molecular weight increases with the decrease of polymerization temperature; no fixed melting point, 80-85 ° C begins to soften, 130 ° C becomes viscoelastic state , 160 ~ 180 ° C began to transform into a 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 production of general-purpose plastics, 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, foam materials, sealing materials, fibers, etc.
