Ergoterm OTGO-S is a thermal stabiliser of emulsion and suspension PVC and its copolymers. Recommended for the processing of hard and semi-hard PVC processed by calendering, extrusion and injection. Due to the content of sulphur, it should not be used together with stabilisers containing lead or cadmium.
Ergoterm OTGO-S does not have lubricating properties – it is recommended to use it with glycerol esters or salts of fatty acids.
Ergoterm OTGO-TM is an oily liquid of a pale yellowish colour. During storage, the product may precipitate a small amount of white precipitate, which does not deteriorate the stabilising properties.
