Pvc becomes the second largest polymer in the world and the use of pvc film materials
May 25, 2018

Vinyl chloride, also known as vinyl chloride, is a flammable gas and is a colorless gas with an ether-like odor; its relative density with respect to water is 0.91 and its relative density with respect to air is 2.15. This product is flammable, ignition temperature is 415 °C, the explosion limit of 3.6% to 31.0% (volume fraction). This product is slightly soluble in water, soluble in most organic solvents such as ethanol, ether and acetone. It is also a special product produced after the development of pvc membrane.

Polyvinyl chloride (PVC) is one of the five general-purpose plastics. Its current production is second only to polyethylene in the world, ranking second. Pvc resin has a relatively strong polarity and can be plasticized, in use with pvc film, pvc packaging materials, etc., it has good processing performance, can produce a variety of properties from hard to soft products. It is precisely because of this superb plasticity, and the great difference in strength changes, so its scope of use has been greatly expanded, and it is involved in all walks of life. This is also the main reason why it can be the second largest polymer in the world.http://www.pvcpackingchina.com/
