Now PVC Stabilizers are Required to be environment conscious
Polyvinyl chloride (PVC) is an essential material for our daily lives. It is used in everything from rigid products like pipes and window profiles to flexible products such as electrical cables and wrapping film.
Stabilizers are essential materials for these PVC products to show durability and/or increase mold stability. Metallic salts are main ingredient of the stabilizers and optimized for each applications.
Lead compounds have been used for a long time for rigid PVC, such as pipes and window profiles, and wire jacket etc. However, these days lead is more and more avoided to use due to its toxicity.
