Polyvinyl chloride has good electrical insulation properties, can
be used as a low-frequency insulation material, and its chemical
stability is also good. Due to the poor thermal stability of
polyvinyl chloride, long-term heating will cause decomposition,
release HCL gas, and discolor the polyvinyl chloride. Therefore,
its application range is narrow, and the use temperature is
generally between -15 and 55 degrees.

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.
