Very low volatility
High melting point and molecular weight keep it in the polymer during hot processing.
SUNNOX® 330 is a high-melting, high-molecular-weight hindered phenolic antioxidant. Its very low volatility and extraction suit polyolefin pipe, wire and cable, and engineering plastics processed at high temperature.
Antioxydant 330 (1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzène) melts at 240–245 °C and has a molecular weight of 775.2, so it stays in the polymer at high processing temperatures and resists extraction by water. It is used in PE pipe, PP, wire and cable insulation, PA and PET.
High melting point and molecular weight keep it in the polymer during hot processing.
Suited to pipe and parts in contact with hot water.
Good color retention in finished parts.

| Votre exigence | Ce qui fonctionne habituellement |
|---|---|
| Stabilité de la couleur et de l'écoulement à l'état fondu pendant l'extrusion ou le moulage | Phosphite antioxydant secondaire (168) avec un primaire phénolique |
| Vieillissement thermique à long terme en service | Primaire phénolique à haut poids moléculaire (1010), souvent avec un thioester (DLTDP / DSTDP) |
| Couche mince, fibre, mélange à bas point de fusion | Phénolique à bas point de fusion (1076) pour une dispersion facile |
| Traitement répété / contenu recyclé | Relever la part de phosphite dans le mélange et vérifier le jaunissement après chaque passage |
| Stockage humide ou long transit | Phosphite résistant à l'hydrolyse tel que 168; garder les sacs scellés |
| Articles à contact alimentaire | Ask for the grade-specific food-contact statement before trials |
| Remplacement d'une note existante | Envoyez votre TDS ou COA actuel; we match on the parameters you approve |

Définissez les niveaux dans votre propre essai. Le bon niveau dépend de la résine, résidu de catalyseur, température de traitement et durée de vie. Les antioxydants primaires et secondaires effectuent des tâches différentes et ne sont pas interchangeables.
25 kg net bags or cartons with a PE inner liner. Palletized.
Keep sealed in a cool, sec, ventilated place away from heat and direct sun. See the SDS for full handling details.
Regular grades are usually in stock. For large volumes, lead time is confirmed in the quotation. We quote FOB and CIF.
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.
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.
For powders: essai, 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.
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.
Start with your polymer, quantité et destination. Add your current grade or specification and we will quote against it.

Le niveau dépend de votre polymère, épaisseur de la pièce, autres additifs et conditions d'essai, alors mets-le dans ton propre essai. La TDS est disponible sur demande.
It does not melt at normal polyolefin processing temperatures, so use a fine powder or a masterbatch and good mixing.
Oui. 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.
Send us the agreed specification and the COA showing the difference (parameter, unité et méthode de test). 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.
