Visão geral do produto & principais benefícios
BHT (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.
Versatile
Used in oils, fuels, borracha, adesivos, plastics and polymer production.
Easy to dissolve
Soluble in oils and most organic solvents.

Seleção & comparação
Selecting an Antioxidant System
| Sua necessidade | O que geralmente funciona |
|---|---|
| Color and melt-flow stability during extrusion or molding | Phosphite secondary antioxidant (168) with a phenolic primary |
| Long-term heat aging in service | High-MW phenolic primary (1010), often with a thioester (DLTDP / DSTDP) |
| Thin film, fibra, low-melting compounding | Lower-melting phenolic (1076) for easy dispersion |
| Repeated processing / conteúdo reciclado | Raise the phosphite share in the blend and check yellowing after each pass |
| Humid storage or long transit | Hydrolysis-resistant phosphite such as 168; keep bags sealed |
| Food-contact articles | Ask for the grade-specific food-contact statement before trials |
| Replacing an existing grade | Envie seu TDS ou COA atual; we match on the parameters you approve |

*Starting points for trials, not fixed recommendations. The right level depends on resin, catalyst residue, processing temperature and service life. Primary and secondary antioxidants do different jobs and are not interchangeable.
Embalagem & armazenar

25 kg net bags or cartons with a PE inner liner. Palletized; private-label packing on request.
Armazenar
Keep sealed in a cool, seco, ventilated place away from heat and direct sun. See the SDS for full handling details.
Tempo de espera & terms
Typically 3–15 business days from order confirmation, depending on quantity. FOB, CIF or DAP to major ports.
Do primeiro e-mail ao fornecimento aprovado
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 os números que importam
For powders: ensaio, 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.
Bloqueie os termos de fornecimento
Agree packaging, monthly volume, destination port and required documents up front. Um número CAS correspondente por si só não qualifica uma nova fonte; run your trial and keep the approved lot COA as the reference.

Is this BHT food grade?
Comida, 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 ou 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.
Posso obter uma amostra antes de fazer o pedido?
Sim. Diga-nos o polímero, o teste que você planeja realizar e a quantidade necessária. As amostras são enviadas com um COA para que você possa comparar o lote com o material atual.
E se um COA não corresponder à especificação acordada?
Envie-nos a especificação acordada e o COA mostrando a diferença (parâmetro, unidade e método de teste). Verificamos com o registro do lote de produção antes de você aceitar o material, e substitua ou teste novamente quando o lote estiver fora das especificações.
