Two functions in one
Phenolic and thioether groups in one molecule simplify the package.
SUNNOX® 1520 is a liquid multifunctional phenolic antioxidant with built-in thioether groups. It protects elastomers, adhesives and lubricants with a single, easy-to-dose additive.
항산화제 1520 (2,4-두번(octylthiomethyl)-6-메틸 페놀) combines a hindered phenol and thioether functions in one molecule, giving both radical-scavenging and hydroperoxide-decomposing action. It is used in synthetic rubbers (SBR, BR, SBS, SIS), hot-melt adhesives and lubricants, and is easy to meter as a liquid.
Phenolic and thioether groups in one molecule simplify the package.
Easy to add to rubber latex, solutions and adhesives.
SBR을 보호합니다, BR and SBS during finishing, storage and processing.

| 귀하의 요구 사항 | 일반적으로 작동하는 것 |
|---|---|
| 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, 섬유, low-melting compounding | Lower-melting phenolic (1076) for easy dispersion |
| Repeated processing / 재활용 콘텐츠 | 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 |
| 기존 등급 대체 | 현재 TDS 또는 COA 보내기; 우리는 귀하가 승인한 매개변수와 일치합니다 |

*시험의 출발점, 고정되지 않은 추천. The right level depends on resin, catalyst residue, processing temperature and service life. Primary and secondary antioxidants do different jobs and are not interchangeable.
일반적으로 25 kg pails or 200 kg 드럼; 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.
일반적으로 주문 확인 후 영업일 기준 3~15일, 수량에 따라. 본선 인도, 주요 포트에 대한 CIF 또는 DAP.
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: 시험, 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. 일치하는 CAS 번호만으로는 새로운 출처에 적합하지 않습니다.; run your trial and keep the approved lot COA as the reference.
Start with your polymer, 수량 및 목적지. Add your current grade or specification and we will quote against it.

Usually not: its built-in thioether groups give the synergy that other packages get from adding DLTDP or DSTDP.
Commonly 0.1–0.5%, depending on rubber type and storage requirements. Confirm in your trial.
Less often; it is mainly used in elastomers, adhesives and oils. For polyolefins 1010 + 168 is the usual choice.
