인위적인 & Buying Information
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: 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.

Is BBMC staining?
아니요, 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?
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.
