PET is ethyl phenylacetate, and PVC is PVC; PET is transparent material, and PVC is mixed with calcium powder.
Combustion method can distinguish: polyester resin (PET), transparent appearance. Combustibility is flammable, and it will continue to burn after leaving the flame. It melts near the flame, melts and burns, and continues to burn when it leaves the flame. A few have smoke, with a very weak sweetness, gray hard round, black or light brown; polyvinyl chloride (PVC) is transparent to opaque in appearance, hard in quality, soft or molten Temperature range: 75~90°C, the combustion flame state is yellow on top and green on the bottom, with white smoke and pungent sour taste, extinguishes after leaving the fire, and becomes brittle after burning.
PVC is quite hard and has good chemical resistance, but is brittle and hard, has less elasticity, and has combustion-supporting and self-extinguishing properties; PET has high tensile strength, stiffness and hardness, and thermal properties. The long-term use temperature of PET can reach 120 degrees, and its water absorption Small, good chemical stability, good electrical insulation.
