Irganox®  1010

Phenolic primary antioxidant for processing and long-term thermal stabilization

Characterization                        Irganox 1010 – a sterically hindered phenolic antioxidant – is a highly effec-

tive, non discoloring stabilizer for organic substrates such as plastics, syn- thetic 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

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.

        Guidelines for use                    Already 0.05 % – 0.1 % ppm of Irganox 1010 provide long-term thermal sta-bility 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 adhe- sives 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.
