What is the application of PVC

PVC can be used in water pipes, household pipes, house siding, commercial machine casings, electronic product packaging, medical equipment, food packaging, etc.

pvc is polyvinyl chloride, real polyvinyl chloride is non-toxic. Toxic is vinyl chloride, and polymers all have the problem of high degree of polymerization. When the degree of polymerization is high enough and the content of vinyl chloride drops to a certain value, it is non-toxic PVC!

PVC is not poisonous, it is only poisonous when various toxic additives such as heat stabilizers and plasticizers are added! The shrinkage of some PVC is as large as 2%!

PVC material will change color after a period of time; PVC is not good for light, oxygen and heat, and it is easy to degrade, causing the color of PVC products to change. The order of change is: white----pink----light yellow---- Brown----reddish brown----reddish black----black.

PVC is also very commonly used in wire and cable plugs and transparent packaging products!

PVC (Polyvinyl Chloride) - (CH2- CH2) - | CH3

It is generally believed that PVC containing less than 15% plasticizer is called hard PVC, while PVC containing more than 15% plasticizer is called soft PVC. PVC used in toys is mostly soft PVC, 35~90 degrees.
