BHT Antioxidant Supplier
SUNNOX® BHT (butylated hydroxytoluene) is a low-cost phenolic antioxidant used in fuels, смазочные материалы, резина, plastics and many industrial products. Еда, feed and pharma grades are a separate, grade-specific request.
КАС 128-37-0 · Hindered phenol · Primary antioxidant
Обзор продукта
БХТ (2,6-di-tert-butyl-4-methylphenol) is one of the most widely used antioxidants. Its low molecular weight (220.4) makes it effective and economical, but also volatile, so it suits low-temperature applications, liquids and in-process stabilization rather than long-term protection of plastics processed at high temperature.
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
Versatile
Used in oils, fuels, резина, клеи, plastics and polymer production.
Easy to dissolve
Soluble in oils and most organic solvents.

Technical & Buying Information
Antioxidant BHT 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: анализ, melting range, volatiles and light transmittance at 425/500 нм (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 this BHT food grade?
Еда, feed and pharma grades are separate products with their own specifications and certificates. Tell us the end use and we quote the right grade.
Why not use BHT in all plastics?
Its low molecular weight makes it volatile at high processing temperatures, so higher-MW phenolics such as 1010 или же 1076 are preferred for long-term protection.
What dosage is typical?
Very application-specific: from about 0.01% in fuels to 0.5% in some polymers. Tell us the application.
Can I get a sample before ordering?
Да. 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.
