Heat resistant additives for plastics

Disclaimer: This document provides guidance and is not a legally binding interpretation and shall therefore not be relied upon as legal advice.

Thermal degradation

During the processing of plastics and rubbers the present polymers are subject of various degradation processes such as oxidation, UV-damage or thermal degradation.

Processing usually results in temperatures well above 180 degrees celsius. These high temperatures will literally cause plastic materials to fall apart and the loss of its required properties.

Heat resistant additives or heat stabilisers are added to plastics to prevent the decomposition of the polymer during processing. Heat stabilisers prevents also degradation or discolouration fo the plastics.
Heavy metal salts of lead, tin, barium or calcium and zinc, or organotin compounds may be used as heat stabilisers.

Make sure that heat stabilisers are not restricted or banned in your destination markets.
