What Is Antioxidant 168 Used For? 애플리케이션, Specs and Sourcing
Chemical Identity
- Chemical name: 트리스(2,4-di-tert-butylphenyl) 인화물
- CAS 번호: 31570-04-4
- Molecular weight: 647.0 g/mol
- 모습: White crystalline powder or granules
- 녹는 점: 183–187°C
- Commercial equivalents: 이르가포스 168, Doverphos S-680
How It Works
As a secondary antioxidant, 항산화제 168 decomposes hydroperoxides formed during melt processing, converting them to stable alcohols before they generate radicals. This protects the polymer during high-temperature extrusion and injection molding, preserving melt flow, 색상, and molecular weight.
애플리케이션
- Polypropylene (PP): Standard stabilization partner with Antioxidant 1010 또는 1076
- Polyethylene (체육): Critical in HDPE/LLDPE pipe compounds and film
- ABS, HIPS, and styrenic polymers: Color and MFI stabilization
- Engineering plastics (아빠, PBT, 애완 동물): High-temperature processing stability
- Thermoplastic elastomers (TPE, TPU): Color retention
- Adhesives and hot-melt systems: Processing viscosity stability
Typical Dosage
Combined loading with Antioxidant 1010 ~에 1:1 또는 1:2 ratio: 0.1–0.3% in polyolefins; 0.2–0.5% in engineering plastics.
자주하는 질문
Is Antioxidant 168 the same as Irgafos 168?
Chemically identical (CAS 31570-04-4). 이르가포스 168 is the BASF brand; 항산화제 168 is the generic designation used by Chinese manufacturers.
Is it food-contact approved?
예. FDA에 등재됨 21 CFR §178.2010 and EU Plastics Regulation 10/2011. Specific migration limits apply.
