Color and melt-flow protection
Keeps yellowness index and MFR stable through extrusion, molding and regrind, where most processing damage happens.
SUNNOX® 168
항산화제 168 Supplier for Polymer Processing
SUNNOX® 168 is a hydrolysis-resistant phosphite secondary antioxidant. Blended with a phenolic primary such as 1010 또는 1076, it protects color and melt flow while polyolefins and engineering plastics are extruded and molded.

제품개요 & 주요 이점
항산화제 168 decomposes the hydroperoxides that form when polymer melts are sheared and heated, so it stops the chain reaction that causes yellowing, gels and melt-flow drift during processing. It is rarely used alone: the standard approach is a blend with a phenolic primary antioxidant, which carries the long-term protection in service. 168:1010 ~에 1:1 또는 2:1 is the most common starting blend in PP and PE.
Works with your phenolic
Synergistic with 1010 그리고 1076. Adding 168 often lets you hold or reduce the phenolic level for the same processing stability.
Hydrolysis resistant
More tolerant of humid storage and long sea transit than many other phosphites, so the powder stays free-flowing and active.

폴리머별 응용
Pick a material family to see how 168 일반적으로 사용되는 것과 평가판 전에 확인해야 할 사항.
Polyolefins — PE & PP
The largest use of 168. Typical packages: 168:1010 1:1 또는 2:1 for PP injection and fiber, 168:1076 for film. Total package levels of about 0.1–0.3% in PP and 0.05–0.15% in PE film are common starting points.
시험 전 확인
- Resin grade, catalyst type and MFR target

Polyamide — PA
Used with a phenolic primary to limit discoloration during compounding of PA6 and PA66, including glass-filled grades.
시험 전 확인

Polycarbonate — PC
Helps protect clarity and color at the high melt temperatures PC needs. Usually dosed low, alongside the base resin stabilizer.
시험 전 확인

- Melt temperature and optical requirements
- Existing stabilizer system
ABS & Styrenics
Added with a phenolic antioxidant to reduce yellowing and property loss during compounding and molding of ABS and HIPS.

Selecting an Antioxidant System
| 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 |

첫 번째 이메일부터 승인된 공급까지
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.
중요한 숫자를 비교하세요
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.
공급 조건 고정
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.

What ratio of 168 에게 1010 should I start with?
1:1 그리고 2:1 (168:1010) are the most widely used starting blends in polyolefins. Use 2:1 when processing stability and color are the main concern, 1:1 when long-term heat aging matters as much. Confirm the ratio in your own trial.
항산화제 가능 168 be used alone?
It can, but it is not recommended. 168 protects during processing; it does little for long-term aging in service. Pair it with a phenolic primary antioxidant such as 1010 또는 1076.
Which COA parameters should I check on incoming lots?
시험, melting range, volatiles and light transmittance at 425 그리고 500 nm. Transmittance is the quickest indicator of color quality in the final part.
