1. 폴리올레핀
High-density polyethylene (HDPE), polypropylene (PP), etc. It is an excellent antioxidant, commonly used in pipes and injection-molded products, providing long-lasting thermal stability protection.

2. 엔지니어링 플라스틱
Polyamide (PA), polyester (PET/PBT), ABS resin, etc. Prevents high-temperature oxidation during processing, maintaining the material’s mechanical properties and appearance.

3. Elastomers
Polyurethane (PU), natural rubber and synthetic rubber, etc. Delays the aging of rubber products and extends their service life.

4. Other Materials
Polyvinyl chloride (PVC), synthetic fibers, adhesives and coatings, etc. Used as an auxiliary stabilizer in specific formulations.

🔍 How to Choose and Use
In practical applications, the following points require special attention:

Key Application Areas: Due to its excellent thermal stability and low volatility, it is particularly suitable for products requiring high-temperature processing (such as extrusion and injection molding) or long-term use in high-temperature environments. For example, polyolefin pipes, automotive parts, and wire and cable insulation materials are typical application scenarios.

Dosage Reference: The general addition amount is small, varying depending on the resin type and requirements. For example, the recommended dosage in polyolefins is usually 0.05% – 0.5% (by weight).

시너지 효과: In actual formulations, antioxidant 1330 is often used in combination with auxiliary antioxidants such as phosphites and thioesters, which can produce a significant synergistic effect and provide more comprehensive antioxidant protection.
