Irganox® 1010 is used in polyolefins such as polyethylene, polypropylene, polybutene, as well as, in olefin co-polymers such as ethylene vinyl acetate co-polymers. It is also recommended for the processing of polymers such as polyacetals, polyamides, and polyurethanes, polyesters, PVC, styrene homo- and co-polymers, ABS, elastomers such as butyl rubber (IIR), SBS, SEBS, EPM, and EPDM, other synthetic rubbers, adhesives, natural and synthetic tackifiers resins, and other organic substrates. It has good compatibility, high resistance to extraction, low volatility, and odorless. Irganox® 1010 can be used in combination with other additives such as co-stabilizers (thioethers, phosphites, phosphonites), light stabilizers, and other functional stabilizers. Irganox® 1010 is recommended for applications such as: • Solvent-based coating applications • Tackifier resins • Hot-melt adhesives | |
