Difference Between PVC and Lead-Free PVC–XXR

introduce:
PVC (polyvinyl chloride) is a common thermoplastic polymer used for both industrial and domestic purposes. Lead, a toxic heavy metal, has been used in PVC yarn for many years, but its adverse effects on human health and the environment have led to the development of PVC alternatives. In this article, we will discuss the differences between PVC and lead-free PVC.
What is Lead-Free PVC?
Lead-free PVC is a type of PVC that does not contain any lead. Due to the absence of lead, lead-free PVC is safer and more environmentally friendly than traditional PVC. Lead-free PVC is usually made with calcium, zinc or tin stabilizers instead of lead-based stabilizers. These stabilizers have the same properties as lead stabilizers, but without the adverse effects on health and the environment.

The difference between PVC and lead-free PVC
1. Toxicity
The main difference between PVC and lead-free PVC is the presence or absence of lead. PVC products often contain lead stabilizers that can leach out of the material and cause environmental damage. Lead is a toxic heavy metal that can cause neurological and developmental problems, especially in children. Lead-free PVC eliminates the risk of lead formation.
2. Environmental impact
PVC is not biodegradable and can remain in the environment for hundreds of years. When incinerated or improperly disposed of, PVC can release toxic chemicals into the air and water. Lead-free PVC is more environmentally friendly because it does not contain lead and can be recycled.
3. Attributes
PVC and lead-free PVC have similar properties, but there are some differences. Lead stabilizers can improve PVC’s properties such as thermal stability, weatherability and processability. However, lead-free PVC can achieve similar properties through the use of additional stabilizers such as calcium, zinc and tin.
4. Cost
Lead-free PVC may cost more than conventional PVC due to the use of additional stabilizers. However, the cost difference is not significant and the benefits of using lead-free PVC outweigh the costs.
