1. Core Antioxidant in the Polyester Industry

As an additive antioxidant before the polycondensation of polyesters (PET, PBT, etc.), it has both catalytic and anti-aging effects, inhibiting high-temperature polycondensation and thermal oxidative degradation during processing, improving resin color and thermal stability. Suitable for polyester products such as fibers, bottle flakes, and films.

2. Antioxidant and Light Stabilizer for Polyamide Materials

Used in polyamide (nylon) products, it has both antioxidant and auxiliary light stabilizing functions. It can be used synergistically with UV absorbers to reduce the degradation of polyamide caused by heat, oxygen, and light during processing and use, extending the product’s service life.

3. Stabilizer for General-Purpose and Engineering Plastics

Added to general-purpose plastics such as polypropylene, polyethylene, polystyrene, and PVC, as well as engineering plastics such as PC and ABS, it inhibits thermal and oxidative aging of materials, preventing yellowing, brittleness, and cracking, maintaining mechanical properties and appearance. Suitable for automotive parts, electronic appliance housings, food packaging, and other applications.

4. Polyester Raw Material Stabilizer

Used in the storage and transportation of polyester raw materials such as dimethyl terephthalate (DMT) to inhibit oxidative deterioration and ensure the stability of product quality in subsequent polyester synthesis.

5. Oil and Polymer Processing Aid

As an antioxidant additive for lubricating oils, hydraulic oils, and other oils, it inhibits the oxidation of oils to form gums and sludge; simultaneously, in polymer processing, it can help improve the extraction resistance of materials and reduce antioxidant migration loss.

6. Organic Synthesis Intermediate

Used in the synthesis of other organophosphorus compounds, it serves as a key intermediate in the preparation and performance optimization of functional molecules in the pharmaceutical, pesticide, and other fine chemical fields.

7. Scientific Research and Biomedical Research

Leveraging its antioxidant properties, it is used in cell protection research related to oxidative stress and in the early exploration of antioxidant drug development, providing material and theoretical support for the biomedical field.
