Introduction to polyvinyl chloride pvc
Polyvinyl chloride pvc plastic is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics. Its trade name is referred to as "chlorine plastic", and the English abbreviation is PVC. Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature is very close to the plasticization temperature, and its mechanical strength is poor.
Therefore, it is impossible to use polyvinyl chloride resin to make products. It is necessary to add plasticizers, stabilizers, fillers, etc. to improve the performance, make polyvinyl chloride plastics, and then process them into various products. Polyvinyl chloride is divided into rigid polyvinyl chloride and soft polyvinyl chloride according to the amount of plasticizer added.
The combustion performance of polyvinyl chloride pvc is not good, it will be extinguished immediately after leaving the fire, the flame is yellow, the lower end is green, and white smoke is emitted.
