液体, easy to meter
Dissolves directly in polyols, plasticizers and oils without a dispersion step.
サノックス® 1135 is a liquid hindered phenolic antioxidant. It is the standard choice for polyols and PU foam to prevent scorch, and is also used in PVC, 接着剤, elastomers and lubricants.

酸化防止剤 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.

Pick an application to see how 1135 is normally used and what to confirm before your trial.

Added to polyol to prevent scorch in slabstock and molded foam, typically 0.1–0.5% on polyol.
Liquid antioxidant for PVC compounds and plastisols.
Used in hot-melts, elastomers and lubricants where a liquid antioxidant is preferred.
通常 25 kg pails or 200 kgドラム缶; IBC on request. Confirm the pack in the quotation.
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.
Typically 3–15 business days from order confirmation, depending on quantity. FOB, CIF or DAP to major ports.
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.
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.
For powders: アッセイ, 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.
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.

High-MW hindered phenolic primary antioxidant for long-term thermal protection with low volatility.
View product →Liquid multifunctional phenolic antioxidant for elastomers, adhesives and lubricants.
View product →Low-melting hindered phenolic primary antioxidant, easy to disperse in film and compounding.
View product →Liquid thioester synergist for ABS, PP and adhesives where a pourable additive is easier to dose.
View product →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.
0.1–0.5% on polyol is a common range, depending on foam density and block size. Confirm in your foam trial.
アッセイ, color and viscosity. Tell us your incoming limits and we quote against them.
はい. 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.
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.
