Présentation du produit & avantages clés
Antioxydant 1076 is octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphényle)propionate, a hindered phenolic antioxidant. In polymer stabilization it is classed as a primary antioxidant, meaning it reacts with radicals formed during oxidation and slows the chain reaction that degrades the polymer.
Its structure combines one hindered phenol group with a long C18 (octadecyl) chaîne.
The SUNNOX® 1076 technical data sheet describes good heat resistance and resistance to water extraction. It lists polyolefins, polyamide, polyester, PVC, ABS resin and petroleum products as application areas, and notes that it is often used together with DLTP (SUNNOX® DLTDP, dilauryl thiodipropionate) for a synergistic antioxidant effect.

1076 contre 168: these two belong to different classes. 1076 is a phenolic primary antioxidant, et 168 is a phosphite secondary antioxidant. They are typically evaluated as partners in a stabilizer package, not as alternatives to each other. 1076 contre 1010: both are hindered phenolic primary antioxidants, but they are different molecules. Changing from one to the other is a formulation change and should be confirmed by trial. This comparison is for initial screening; confirm your choice against each product's TDS and your own test results.

Du premier e-mail à la fourniture approuvée
Define the requirement.
Record the polymer, processus, service conditions and the problem you need to address. The same additive can behave differently in a different resin or additive package.
Match identity and specification, not just the CAS number.
Compare the chemical name, Numéro CAS, physical form and every specification limit with your approved specification. Check the test conditions too. Transmission, par exemple, depends on concentration and solvent.
Keep the TDS and COA separate.
The TDS sets the grade limits. A COA reports results for one batch only. Ask for the COA of the batch you will receive.
Trial before switching.
Agree on sample quantity, test method and acceptance criteria. Then confirm packaging, quantité, destination and required documents before a commercial order.
Dites-nous votre besoin. Nous correspondons à la note.
Tell us your polymer, quantité et destination. If you have a current grade or specification, include it so we can review it against SUNNOX® 1076.

Qu'est-ce qu'un antioxydant 1076 utilisé pour?
Antioxydant 1076 is a hindered phenolic primary antioxidant used to help protect polymers against thermal-oxidative degradation. The SUNNOX® 1076 technical data sheet lists polyolefins, polyamide, polyester, PVC, ABS resin and petroleum products as application areas. Suitability for a specific grade and process should be confirmed by trial.
What is the CAS number of Antioxidant 1076?
The CAS number of Antioxidant 1076 est 2082-79-3. Its chemical name is octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphényle)propionate, and its molecular formula is C35H62O3. When comparing suppliers, match the chemical name and specification as well as the CAS number, because the CAS number alone does not confirm that two grades are interchangeable.
Est antioxydant 1076 a primary or secondary antioxidant?
Antioxydant 1076 is a primary antioxidant. As a hindered phenol, it reacts with peroxy radicals and slows the oxidation chain reaction. Antioxydants secondaires, comme les phosphites et les thioesters, act on hydroperoxides instead. Because the two types work at different points in the reaction, formulators often evaluate them together in one stabilizer package.
Peut antioxydant 1076 replace Antioxidant 1010?
Not automatically. Both are hindered phenolic primary antioxidants, but they are different molecules. Whether one can replace the other depends on the polymer, processing and service conditions, and on your approved formulation. Treat the change as a formulation change: compare both technical data sheets and confirm performance in a controlled trial before approval.
Peut antioxydant 1076 be used with DLTDP or 168?
Oui. 1076 is a phenolic primary antioxidant, and both DLTDP (a thioester) et 168 (a phosphite) are secondary antioxidants. The SUNNOX® 1076 technical data sheet specifically notes synergistic use with DLTDP. The right combination and addition levels depend on your polymer and process and should be established through testing.
What should I check before changing my 1076 fournisseur?
Start with your approved specification. Compare the chemical name, Numéro CAS, forme physique, every specification limit and the test conditions behind them. Review the supplier's technical data sheet and the COA for the batch you will receive, and ask which other documents your end use requires. Then run a controlled trial before approving the new source.
Puis-je obtenir un échantillon avant de commander?
Oui. Des échantillons gratuits sont disponibles pour les acheteurs évaluant le produit pour une utilisation en production. Les frais de port sont à convenir au cas par cas, et chaque échantillon est livré avec un COA.
