Heat Stabilizers

Polymer heat stabilizers are additives used in various polymers to protect them from degradation and maintain their physical and chemical properties when exposed to high temperatures during processing or end-use applications. Heat stabilizers are especially important in polymers that are susceptible to thermal degradation, which can result in discoloration, reduced mechanical properties, and other undesirable effects.

There are basic three types of Nucleating agents,
