1. Polyethylene (PE) Processing

Used in the production and processing of low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE), it inhibits thermo-oxidative degradation in high-temperature processes such as extrusion and injection molding, reducing discoloration and decline in mechanical properties. The typical dosage is 0.05%-0.5%.

2. Polypropylene (PP) Processing

Suitable for the granulation and molding of homopolymer and copolymer polypropylene, improving thermo-oxidative stability and extending product lifespan. Often used in combination with antioxidants such as 1010 and 1076.

3. Synthetic Resins such as ABS, PVC, and AS

Used as an auxiliary antioxidant in resins such as ABS, PVC, AS, and MBS to prevent oxidative aging during processing and use, maintaining stable appearance and performance of products, and preventing contamination and discoloration.

4. Rubber Industry

Used in natural rubber, styrene-butadiene rubber, butadiene rubber, and other synthetic rubbers and adhesives to inhibit thermo-oxidative aging of rubber, improve the heat resistance and weather resistance of vulcanized rubber, and extend the service life of products. The typical dosage is 0.1%-1.0%.

5. Lubricating Greases and Oils

Added to industrial greases, metalworking fluids, hydraulic oils, etc., to inhibit oxidative rancidity and viscosity increase, extend the service life of oils, and protect metal parts from oxidative corrosion.

6. Food and Food Additives

As a fat-soluble antioxidant, used in the preservation of edible oils, oily foods, and fruits and vegetables to delay rancidity and food spoilage.

7. Food Packaging Materials

Due to its low toxicity, it is used in the antioxidant system of food contact plastic packaging (such as PE, PP films and containers) to prevent aging of packaging materials and ensure food safety.

8. Other Polymer Materials

Used in thermoplastic elastomers (TPE), polyurethane (PU), polyesters, and other materials, as well as wire and cable insulation layers, automotive interior parts, etc., to improve the aging resistance of materials and adapt them to long-term outdoor or high-temperature applications.

9. Organic Synthesis Intermediates

Used in the synthesis of other thioester compounds or fine chemical products, serving as a sulfur source and ester group donor in organic synthesis.
