       Irganox 1010 specification

　　Characterization: Irganox 1010 – a sterically hindered phenolic antioxidant – is a highly effective, non discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fats. It protects these

　　substrates against thermo-oxidative degradation.

　　Chemical name: Pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate)

　　CAS number: 6683-19-8

　　Structure: Irganox 1010

　　Chemical formula:

　　Molecular weight: 1178 g/mol

　　Applications:

　　Irganox 1010 can be applied in polyolefins, such as polyethylene, polypro pylene, polybutene and olefin copolymers such as ethylene-vinylacetate copolymers. Also, its use is recommended for the processing of polymers such as polyacetals, polyamides and polyurethanes, polyesters, PVC, sty rene homo- and copolymers, ABS, elastomers such as butyl rubber (IIR), SBS, SEBS, EPM and EPDM as well as other synthetic rubbers, adhesives, natural and synthetic tackifier resins, and other organic substrates.

　　Features/benefits:

　　Irganox 1010 has good compatibility, high resistance to extraction and low

　　volatility. It is odorless and tasteless. The product can be used in combina tion with other additives such as costabilizers (e. g. thioethers, phosphites, phosphonites), light stabilizers and other functional stabilizers. The effective ness of the blends of Irganox 1010 with Irgafos 168 (Irganox B-blends) or with Irgafos 168 and Irgafos FS042 is particularly noteworthy.

　　Product forms: Irganox 1010 white, free-flowing powder

　　Guidelines for use:

　　Already 0.05% – 0.1 % ppm of Irganox 1010 provide long-term thermal stability to the polymer. Concentrations up to several percent may be used depending on the substrate and the requirements of the end application. In polyolefins the concentration levels for Irganox 1010 range between 0.05 % and 0.4 % depending on substrate, processing conditions and long-term thermal stability requirements. The optimum level has to be determined application specific. Concentration levels of Irganox 1010 in hot melt adhesives range from 0.2 % to 1 %, in synthetic tackifier resins, Irganox 1010 concentration ranges between 0.1 % and 0.5 %. Extensive performance data of Irganox 1010 in various organic polymers and applications are available upon request.

　　Physical Properties:

　　Solubility at 20℃ (g/100 g solution)

　　Health & Safety:

　　 Irganox 1010 exhibits a very low order of oral toxicity and does not present

　　any abnormal problems in its handling or general use.

　　Detailed information on handling and any precautions to be observed in the use of the product(s) described in this leaflet can be found in our relevant health and safety information sheet.
