Selection & comparison
Selecting an Antioxidant System
| Your requirement | What usually works |
|---|---|
| Color and melt-flow stability during extrusion or molding | Phosphite secondary antioxidant (168) with a phenolic primary |
| Long-term heat aging in service | High-MW phenolic primary (1010), often with a thioester (DLTDP / DSTDP) |
| Thin film, fiber, low-melting compounding | Lower-melting phenolic (1076) for easy dispersion |
| Repeated processing / recycled content | Raise the phosphite share in the blend and check yellowing after each pass |
| Humid storage or long transit | Hydrolysis-resistant phosphite such as 168; keep bags sealed |
| Food-contact articles | Ask for the grade-specific food-contact statement before trials |
| Replacing an existing grade | Send your current TDS or COA; we match on the parameters you approve |

Set the levels in your own trial. The right level depends on resin, catalyst residue, processing temperature and service life. Primary and secondary antioxidants do different jobs and are not interchangeable.
Packaging & storage
Packaging
25 kg net bags or cartons with a PE inner liner. Palletized.
Storage
Keep sealed in a cool, dry, ventilated place away from heat and direct sun. See the SDS for full handling details.
Lead time & terms
Regular grades are usually in stock. For large volumes, lead time is confirmed in the quotation. We quote FOB and CIF.
From first email to approved supply
Name the failure you want to prevent
Yellowing or melt-flow change during processing points to the phosphite share; embrittlement or cracking after months in service points to the phenolic and thioester share. Note recycled content and the number of extrusion passes.
Start from a proven blend
Most polyolefin packages start from a phenolic primary plus a phosphite secondary, then adjust. Send your current package and we suggest a starting blend for the trial instead of changing several variables at once.
Compare the numbers that matter
For powders: assay, melting range, volatiles and light transmittance at 425/500 nm (a direct read on color). Ask for the same parameters on our COA that appear on your incoming-inspection sheet.
Lock in supply terms
Agree packaging, monthly volume, destination port and required documents up front. A matching CAS number alone does not qualify a new source; run your trial and keep the approved lot COA as the reference.
Tell us your requirement. We match the grade.
Start with your polymer, quantity and destination. Add your current grade or specification and we will quote against it.

3114 or 1010 for fiber?
Both are used. 3114 is often chosen for better gas-fading resistance and compatibility with HALS in fiber.
How much SUNNOX® 3114 should I add?
The level depends on your polymer, part thickness, other additives and test conditions, so set it in your own trial. The TDS is available on request.
Can I use it in outdoor parts?
Yes, it is commonly combined with HALS such as 944 or 622 in outdoor polyolefins.
Can I get a sample before ordering?
Yes. Tell us the polymer, the test you plan to run and the quantity you need. Samples ship with a COA so you can compare the lot against your current material.
What if a COA does not match our agreed specification?
Send us the agreed specification and the COA showing the difference (parameter, unit and test method). We check it with the production batch record before you accept the material, and replace or re-test where the lot is out of specification.
