Plastics, I believe everyone is not unfamiliar, in our daily life, we will all have access to it. However, do you know what PVC is? What is the difference between pvc and general plastic? PChouse will take everyone to understand it.

　　 The difference between PVC and ordinary plastic is that the inside of the plastic contains chlorine, so it cannot directly contact drinking water or food. Secondly, because the molecular chain of PVC plastic is too polar and has poor plasticity, it is often necessary to add more than 40% of plasticizer (plasticizer), and it is often impossible to directly contact drinking water or food.

　　PVC material is used more in building materials because it has an obvious advantage, that is, during outdoor use, because of its different decomposition mechanism, its physical properties are reduced to a relatively small degree, and the price is relatively low.
