The softening point of polyvinyl chloride resin is low, about 75-80℃, and the embrittlement temperature is lower than -50~-60℃. The long-term use temperature of most products should not exceed 55℃, and the special formula can reach 90℃.

If the polyvinyl chloride resin is purely a linear structure with a head-to-sex interface, there are no branches or unsaturated bonds inside, although the C-Cl bond energy is relatively small, the stability of the polyvinyl chloride resin should be relatively high. .

Application of PVC:

Polyvinyl chloride products are mainly used for packaging in various containers, films and rigid sheets. PVC containers mainly produce bottles of mineral water, beverages, cosmetics, and are also used for packaging refined oil.

PVC film can be used to co-extrude with other polymers to produce low-cost laminates and transparent products with good barrier properties. Polyvinyl chloride film can also be used for stretch or heat shrink packaging for packaging mattresses, cloth, toys and industrial goods.
