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 |

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 BBMC staining?
Não, 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.
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.
