Irganox®1010

Phenolicprimaryantioxidantforprocessingand long-term thermalstabilization

Characterization Irganox1010–astericallyhinderedphenolicantioxidant–isahighlyeffec-

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.

Chemicalname Pentaerythritoltetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate)

CASnumber 6683-19-8

Chemical formula 

Molecularweight 1178g/mol

Applications Irganox 1010 can be applied in polyolefins, such as polyethylene, polypro- pylene, polybuteneandolefincopolymers such as ethylene-vinylacetate copolymers. Also, its use is recommended for the processing ofpolymerssuch as polyacetals, polyamidesandpolyurethanes,polyesters, PVC, sty- rene homo- and copolymers, ABS,elastomers such as butyl rubber (IIR), SBS,SEBS,EPMandEPDMaswellasothersyntheticrubbers,adhesives,natural and synthetic tackifier resins, and other organicsubstrates.

Features/benefits Irganox 1010 has good compatibility, high resistance to extraction andlow

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.

Guidelinesforuse Already0.05%–0.1%ppmofIrganox1010providelong-termthermalsta-bility to the polymer. Concentrations up to several percent may be used depending on the substrate and the re 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 re. 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 %.
