Antioxidant 1076 CAS Number: 2082-79-3

Characterization

Antioxidant 1076, a sterically hindered phenolic antioxidant, is highly efficient, non discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation. IRGANOX 1076 is odorless, stable to light and has excellent color retention. It has good compatibility with most substrates, low volatility and high resistance to extraction.

Applications

Antioxidant 1076 can be applied in polyolefins such as polyethylene, polypropylene, polybutene-1 as well as in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates.

Features/benefits

Antioxidant 1076 can be used in combination with other additives such as costabilizers (e.g. thioesters, phosphites, phosphonites), light stabilizers, and other functional stabilizers.

Physical Properties

Handling & Safety

In accordance with good industrial practice, handle with care and prevent contamination of the environment. Avoid dust formation and ignition sources.

Description

Antioxidant 1076 is odorless, tasteless and less toxicity and stable to light so that it can widely used in polymer materials, such as polypropylene polyethylene, polystyrene, polyamide, polyoxymethylene, ABS, synthetic rubber and so on. It is an effective antioxidant in oil and paint, too. Antioxidant 1076 is a nonpolluting nontoxic Antioxidant with good heat-resisting and water-extracting performance. widely applied to polyolefine, polyamnamee, polyester, polyvinyl chlornamee, ABS resin and petroleum product, often used with DLTP for promoting the antioxnameative effect.

Chemical Properties

white crystalline powder

Uses

1076 is a nonpolluting nontoxic antioxidant with good heat-resisting and water-extracting performance. It can be applied in polyolefins, such as polyeth-ylene, polypropylene, polybutene-1 and other polymers such as engineering plastics ,styrenes, polyurethanes, saturated and unsaturated elastomers, styrenics, rubber modified styrenics, segmented block copolymers, and PVC. Also often used with DLTDP for promoting the antioxidative effect.

Uses

Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is a 4 chain-breaking antioxidant. A study shows that Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate can protect the oxidation of soybean phosphatidylcholine liposomes in water dispersion, but cannot protect the oxidation of dimyristoyl phosphatidylcholine liposomes.

Application

Antioxidant 1076 finds application in plastics, rubber, latex, varnishes, adhesives, TPR’s and Hot Melts. In plastics, antioxidant 1076 provides excellent antioxidant performance in Polyethylene, Polystyrene, Polyacetal, PVC, AS resin, Methacrylic resin, Polycarbonate, Polyester, and Polymethyl- pentene as well as many others. In rubbers, Antioxidant 1076 can be used in SBR, EPR, EPDM, Polybutadiene, Neoprene, Nitrile, Polyisoprene, and many other synthetic rubbers. Typical dosage is 0.02% – 0.5% by weight.

General Description

Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is a propionate based phenolic antioxidant that can be used as a polymeric stabilizer by butylphenol functionalities.

Safety

FDA approved for use in indirect food contact applications. This product is of low toxicity to aquatic organisms.
