Antioxidant 9228 Application scenarios
1. General-Purpose Plastics
• Polypropylene (PP): Maintains stable color and melt index during multiple extrusion processes.
• Polyethylene (PE, LDPE, LLDPE): Provides excellent color and melt flow stability.
• Polystyrene (PS, HIPS).
2. Engineering Plastics
• Polycarbonate (PC): Meets high-temperature processing requirements, preventing degradation and discoloration.
• Polyamide/Nylon (PA).
• Polyesters (PET, PBT).
• Polyphenylene oxide (PPO), Polyphenylene sulfide (PPS).
3. Special High-Performance Materials
• Polyether ether ketone (PEEK): Meets the anti-degradation requirements of this special material during high-temperature processing.
• Other high-temperature engineering plastics with processing temperatures exceeding 280°C.
💡 Important Application Scenarios
In addition to being used as a single additive, it also plays a key role in the following specific scenarios:
• Application in BOPP films: Antioxidant 9228 is often compounded with primary antioxidants (such as antioxidant 1010) as a composite additive for biaxially oriented polypropylene (BOPP) films, effectively improving film processing stability, preventing cross-sectional yellowing, and enhancing product quality.
• Synergistic application in special engineering plastics: For special engineering plastics with extremely high processing temperatures (often exceeding 320°C), such as PPA, PA6T, and LCP, antioxidant 9228 can be used synergistically with specific phenolic primary antioxidants (such as 1790) to meet demanding processing thermal stability requirements.
