Very low volatility
High melting point and molecular weight keep it in the polymer during hot processing.
항산화제 330 Supplier for High-Temperature Applications
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.
CAS 1709-70-2 · Hindered phenol · Primary antioxidant
제품개요
항산화제 330 (1,3,5-trimethyl-2,4,6-tris(3,5-디-tert-부틸-4-히드록시벤질)벤젠) 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.
Typical specification. Every shipment is supplied with a batch COA; the limits that apply to your order are confirmed in the quotation and contract.
Key Benefits
Extraction resistance
Suited to pipe and parts in contact with hot water.
Non-discoloring
Good color retention in finished parts.

인위적인 & Buying Information
항산화제 330 구매자 가이드
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: 시험, 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.

When is 330 better than 1010?
When processing temperature is very high or the part is exposed to hot water and extraction. 1010 remains the general-purpose choice.
What dosage is typical?
0.05–0.3% in most polyolefins, usually with a phosphite. Confirm in your trial.
Does it disperse well given its high melting point?
It does not melt at normal polyolefin processing temperatures, so use a fine powder or a masterbatch and good mixing.
Can I get a sample before ordering?
예. 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.
