Polyvinyl chloride (PVC), is the world's third-most widely produced synthetic plastic polymer.
PVC is a white powder with amorphous structure, with a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90 ° C, and decomposition at about 170 ° C. The stability to light and heat is poor, above 100 ° C or over a long period of time. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration, and physical and mechanical properties are also rapidly declining. In practical applications, stabilizers must be added to improve the stability to heat and light.
We can see the products made by pvc everywhere in our daily life. PVC is used to make a variety of imitation leather for luggage, sports, such as basketball, football and rugby. It can also be used to make belts for uniforms and special protective equipment. PVC fabrics for apparel are generally absorbent fabrics such as ponchos, baby pants, faux wallets and various rain boots. PVC is also used in many sports and entertainment products such as toys, records, and sporting goods. And most inflatable bouncer is made by pvc, Including inflatable castle, inflatable slide, inflatable water park, inflatable tents, inflatable games, inflatable water toys, air track, and advertising inflatables.
