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-like junction, it is
afraid of a linear structure, and there is no branching or
unsaturated bond inside. Although the C-Cl bond energy is
relatively small, the stability of the polyvinyl chloride resin
should be relatively high. . However, even if the polyvinyl
chloride resin has a high purity, hydrogen chloride gas will start
to escape at a temperature of 100 ° C or higher or ultraviolet
radiation. It indicates that there are sharp groups or unstable
structures in its molecular structure. The longer the time, the
more degradation, the higher the temperature, the faster the
degradation rate, and the faster the degradation in the presence of
oxygen or air.

The most important feature of PVC is its flame retardant, so it is
widely used in fire protection applications. However, polyvinyl
chloride releases hydrogen chloride and other toxic gases such as
dioxins during combustion.
The burning of PVC is divided into two steps. First, hydrogen
chloride gas and a diene containing a double bond are decomposed by
burning at 240 ° C - 340 ° C, and then carbon combustion occurs at
400 - 470 ° C.
It is one of the largest plastic products in the world. It is cheap
and widely used. The polyvinyl chloride resin is white or light
yellow powder. Different additives can be added according to
different purposes, and polyvinyl chloride plastic can exhibit
different physical properties and mechanical properties. A variety
of hard, soft and transparent articles can be made by adding an
appropriate amount of plasticizer to the polyvinyl chloride resin.
