PUREstab 1098 is a sterically hindered phenolic antioxidant, an efficient, non - discolouring stabilizer for organic substances such as plastics, synthetic fibers, adhesives, elastomers & is specifically effective in polyamide & fibers.
Features & Benefits:
PUREstab 1098 provides excellent processing & long term thermal stability with excellent initial resin colour.
It is superior to copper based systems used as stabilisers for polyamides with respect to colour and resistance to extraction.
It has excellent compatibility with polyamides and other substrates & low volatility.
PUREstab 1098 is especially suited for the stabilisation of polyamide molded parts, fibers & films.
Its use is also recommended in other polymers such as polyacetals, polyesters, polyurethanes, adhesives, elastomers as well as other organic substrates.
Recommended for use at concentrations of 0.05% to 0.5% depending on the polymer type, method of incorporation, application and degree of stability required.
PUREstab 1098 can also be used during polyamide polymerisation in concentration ranging from 0.05% to 0.2% to provide protection of polymer colour properties in subsequent fabrication, spinning or finishing operations. When PUREstab 1098 is incorporated prior to or during the polyamide polymerisation, reaction conditions and chain terminator concentration may require adjustment to compensate for the presence of the antioxidant.
It can be used in combination with other additives such as costabilisers (eg. phosphites, thioethers, hydroxylamines), light stabilisers (eg. UV absorbers, hindered amines), and other functional stabilisers.
This product may be stored upto 2 years in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool & dry place.
