1. High-Temperature Processing Stability of Engineering Plastics:

Compatible with polycarbonate (PC), polyamide (PA/high-temperature nylon), polyester (PET, PBT), polyoxymethylene (POM), polyphenylene ether (PPO), etc., inhibiting thermal degradation and yellowing in high-shear processes such as high-temperature extrusion and injection molding, maintaining melt stability and mechanical properties. Suitable for high-temperature components such as automotive hood parts and electronic connectors.

2. Processing and Long-Term Stability of Polyolefin Products:

Used for injection molded parts, pipes, films, and fibers of polypropylene (PP), polyethylene (LDPE, HDPE, LLDPE), improving color and melt stability after multiple processing steps. Compatible with phenol-free antioxidant-free stabilization systems, suitable for appliance housings, food packaging, and wire and cable insulation.

3. Styrene and ABS Resins:

Applied to polystyrene (PS), ABS, high-impact polystyrene (HIPS), etc., preventing thermo-oxidative aging during processing and use, maintaining product appearance and mechanical properties. Suitable for injection/extrusion molded products such as electronic housings and appliance components. 4. Specialty Engineering Plastics and Elastomers:

Suitable for specialty engineering plastics and elastomers such as polyphenylene sulfide (PPS) and polyetherimide (PEI), inhibiting degradation during high-temperature processing and long-term use, suitable for high-performance applications such as industrial machinery parts and aerospace components.

5. Polyester Powder Coatings:

Used in polyester powder coating systems to prevent oxidative yellowing during baking and curing, improving coating color stability and weather resistance, suitable for surface protection of coated parts in the construction, home appliance, and automotive industries.

6. Transparent and Optical Materials:

Suitable for transparent products such as polymethyl methacrylate (PMMA), PC optical sheets, automotive headlight covers, and lamp covers, maintaining transparency and optical properties during high-temperature processing, reducing yellowing and haze increase.

7. Food Contact Materials:

Complies with relevant safety standards such as FDA and EU-SCF, and can be used in food contact grade plastics and packaging materials, inhibiting thermo-oxidative degradation during processing and use, ensuring material safety and stability.

8. Synergistic Effect of Composite Stabilizing Systems:

Often combined with hindered phenolic primary antioxidants (such as 1010, 1098) and hindered amine light stabilizers (HALS) to construct highly efficient antioxidant-weather-resistant systems, suitable for outdoor weather-resistant products and polymer materials used for long-term high-temperature applications.
