The softening point of the polyvinyl chloride resin is low, about 75-80 ° C, and the embrittlement temperature is lower than -50 ~ -60 ° C. The long-term use temperature of most products should not exceed 55 ° C, and the special formula can reach 90 ° C. If the polyvinyl chloride resin is purely a head-shaped junction, it is afraid of a linear structure, and there are no branches and unsaturated bonds inside. Although the C-Cl bond energy is relatively small, the stability of the polyvinyl chloride resin should be relatively high. .
Polyvinyl chloride has poor stability to light and heat. The softening point was 80 ° C and decomposition began at 130 ° C. Without heating the stabilizer, the polyvinyl chloride starts to decompose at 100 ° C, and decomposes faster at 130 ° C or higher.
It is decomposed by heat to release hydrogen chloride gas (hydrogen chloride gas is a toxic gas) to discolor, from white → light yellow → red → brown → black. The ultraviolet rays and oxygen in the sunlight cause photo-oxidative decomposition of the polyvinyl chloride, thereby lowering the flexibility of the polyvinyl chloride and finally becoming brittle.
