dip moulding

This is a simple process used to make products such as rubber gloves. A hot metal tool is dipped into a bath of plastisol. The liquid gels on the surface of the tool to form a layer of polyvinyl chloride (PVC). This is a one-way reaction.

The environmental credibility of PVC has been under investigation in recent years due to dioxins, harmful organic compounds that are given off during both the production and the incineration of the material.
