Characterization |
Antioxidant 1330 – a sterically hindered phenolic antioxidant – is as highly effective stabilizer for organic substrates such as polymers, synthetic fibers, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation. |
|
Applications |
Antioxidant 1330 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 homoand copolymers. It may also be used in PVC, polyurethanes, elastomers, adhesives, and other organic substrates. |
|
Features/benefits |
Antioxidant 1330 has good compatibility with most substrates, high resistance to extraction and is odorless. It offers also excellent dielectrical properties. The product can be used in combination with other additives such as costabilizers (e.g. thioethers, phosphites, phosphonites), light stabilizers and other functional stabilizers. The effectiveness of the blends of Irganox 1330 with Irgafos 168 (Irganox B-blends) is particularly noteworthy. Irganox 1330 is particularly recommended for polyolefin applications requiring good water extraction resistance combined with low color development. Furthermore, Irganox 1330 reduces water carry-over in polypropylene tape extrusion. |

Guidelines for use |
In polyolefins, the concentration levels for Antioxidant 1330 range typically between 0.05 % and 0.3 % depending on substrate, processing conditions and long-term thermal stability requirements. The optimum level is application specific. Concentration levels of Antioxidant 1330 in hot melt adhesives range from 0.2 % to 1 %, in synthetic tackifier resins, Irganox 1330 concentration ranges between 0.1 % and 0.5 %. Extensive performance data of Irganox 1330 in various organic polymers and applications are available upon request. |
