Vulcanization is a process by which latex is heated in the presence of sulfur.
This improves the elasticity and thermostability. Ammonia and other preservatives are used to disrupt rubber particles and prevent coagulation. Vulcanized latex is poured into molds or coat products. Dipped products include gloves, balloons, condoms, adhesives foam and carpet backing. In dipped products the latex proteins migrate to the surface of the molds.
