Stabilisers are a required addition to plastic. Without a heat stabiliser, for example, the plastic would burn during the production process rendering it unusable.

What are heat stabilisers?

Heat stabilisers are additives designed to protect PVC from burning from the heat during the manufacturing process.

Is PVC heat sensitive?

Yes, PVC is heat sensitive. Heat breaks down the chemical bonds contained in PVC and releases hydrochloric acid which degrades PVC.

Why is PVC heat sensitive?
