Обзор продукта
антиоксидант 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.
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
Scorch protection
Protects flexible PU foam against core discoloration during foaming.
Low volatility for a liquid
Suitable for PVC plastisols, adhesives and elastomers.

Applications by Polymer
Pick an application to see how 1135 is normally used and what to confirm before your trial.
Polyols & Flexible PU Foam
Added to polyol to prevent scorch in slabstock and molded foam, typically 0.1–0.5% on polyol.
What to confirm for your application
- Polyol type and foam grade
- Foam density and block size
- Current anti-scorch package
ПВХ & Plastisols
Liquid antioxidant for PVC compounds and plastisols.
What to confirm for your application
- Formulation and plasticizer
- Температура обработки
- Color target
Клеи, Эластомеры & Смазочные материалы
Used in hot-melts, elastomers and lubricants where a liquid antioxidant is preferred.
What to confirm for your application
- Base polymer or oil
- Operating temperature
- Existing antioxidant

Technical & Buying Information
антиоксидант 1135 Руководство покупателя
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.

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?
анализ, color and viscosity. Tell us your incoming limits and we quote against them.
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.
