Visão geral do produto & principais benefícios
Antioxidante 1135 (C7–C9 branched alkyl ester of 3,5-di-tert-butyl-4-hydroxyphenylpropionic acid) dissolves directly in polyols, plasticizers and oils, so it is simple to meter. In flexible PU foam it protects against core discoloration (scorch) during the exothermic foaming step, usually together with an aminic or phosphite co-stabilizer.
Scorch protection
Protects flexible PU foam against core discoloration during foaming.
Low volatility for a liquid
Suitable for PVC plastisols, adhesives and elastomers.

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 |

Embalagem & armazenar
Embalagem
Tipicamente 25 kg pails or 200 tambores de kg; IBC on request. Confirm the pack in the quotation.
Armazenar
Keep containers closed, away from heat and direct sun. Warm gently and mix before use if the liquid has thickened in cold weather. See the SDS.
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.

Why use a liquid antioxidant in PU foam?
It dissolves directly in the polyol, so there is no dispersion step and the dose is uniform. That matters for scorch protection in large foam blocks.
What dosage is typical?
0.1–0.5% on polyol is a common range, depending on foam density and block size. Confirm in your foam trial.
Which COA parameters matter?
Ensaio, color and viscosity. Tell us your incoming limits and we quote against them.
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.
