Why use Antioxidants?
Practically all polymer materials undergo oxidative degradation reactions occurring at one or all of the manufacturing, processing and end use stages.
Antioxidants are highly effective in preventing this degradation to the extent that color development, physical and mechanical property loss is kept within acceptable limits.
The diagram below represents the complex series of chemical reactions that take place when polyolefin’s degrade in the presence of oxygen and how antioxidants can intervene in this process.

The wild range of antioxidants & stabilizers offered by Everspring's Polymer Additives business can play an important role in counteracting the effects of degradation.
Everspring Corp. manufactures and markets a wide range of products to serve the chemical industry worldwide.
Primary Antioxidants
Evernox®10 : EVERNOX-10/GF can be applied in polyolefins, such as PE and PP as well as olefin copolymers like EVA. Its use is also recommended in various polymers such as POM, PA, PUR, PES, PBT, PET, PVC, styrenics like IPS, ABS, elastomers like SBS, SEBS, EPM and EPDM, as well as other synthetic rubbers, adhesives, tackifier resins, and other organic substrates.
Evernox®76 : EVERNOX-76/GF/GD can be applied in polyolefins, such as PE and PP as well as in other polymers such as styrenics, styrene homo and copolymers like IPS, ABS, and MBS, engineering plastics like PBT, PET and PUR, elastomers like SBS, SBR, BR, as well as other synthetic rubbers, adhesives, tackifier resins, and other organic substrates.
Evernox®1135 : For the stabilization of polyurethane flexible slabstock foams, EVERNOX-1135 prevents the formation of peroxides in the polyol during storage, transport, and further protects against scorching during foaming.
Evernox®1330 : EVERNOX-1330/GF is used in polyolefins e.g. polyethylene, polypropylene, polybutene for the stabilization of pipes, molded articles, wires and cables, dielectric films etc. Furthermore, it is applied in other polymers such as engineering plastics like linear polyesters, polyamides, and styrene homo- and copolymers. It may also be used in PVC, polyurethanes, elastomers, adhesives, and other organic substrates.
Evernox®3114 : EVERNOX-3114/GF is a highly effective sterically hindered phenolic antioxidant that can be applied in organic substrates such as PE, PP, ABS, PS, SBS, PVC, synthetic fibers, elastomers, waxes, adhesives, oils and fats. It is odorless, stable, and has a good compatibility with most substrates, low volatility and high resistance to extraction.
Evernox®1790 : EVERNOX-1790 has minimal color contribution, low volatility, and good solubility/ migration balance. It is also compatible and can be used in combination with light stabilizers such as UVA and HALS, and other functional stabilizers.
Evernox®MD 1024 : EVERNOX-MD1024 is a highly efficient hindered phenolic antioxidant and metal deactivator for the stabilization of polyolefins and certain thermo-plastic elastomers, utilized as primary insulation in contact with copper, both during processing and long term service use.
Secondary Antioxidants
Everfos® 16 : EVERFOS-168 /GF is a hydrolytically stable phosphite processing stabilizer as a secondary antioxidant. It reacts with hydroperoxides, formed by autoxidation of polymers, to yield non-radical products, therefore called hydroperoxide decomposer. It is synergistically combined with other primary antioxidants in the EVERNOX range to be used in polyolefins or olefin-copolymers.
