Technical & Buying Information

Selecting an Antioxidant System

Your requirementWhat usually works
Color and melt-flow stability during extrusion or moldingPhosphite secondary antioxidant (168) with a phenolic primary
Long-term heat aging in serviceHigh-MW phenolic primary (1010), often with a thioester (DLTDP / DSTDP)
Thin film, fiber, low-melting compoundingLower-melting phenolic (1076) for easy dispersion
Repeated processing / recycled contentRaise the phosphite share in the blend and check yellowing after each pass
Humid storage or long transitHydrolysis-resistant phosphite such as 168; keep bags sealed
Food-contact articlesAsk for the grade-specific food-contact statement before trials
Replacing an existing gradeSend your current TDS or COA; we match on the parameters you approve

Antioxidant BBMC Buyer Guide

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.

Antioxidant BBMC FAQ

Is BBMC staining?

No, it is a non-discoloring antioxidant suited to light-colored products.

What dosage is typical?

About 0.2–1.0% depending on application. Confirm in your test.

BBMC or 2246?

BBMC has a higher melting point and is often chosen for hot-melt adhesives; 2246 is common in rubber and latex.

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.
