Applications of 3846-71-7
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Stabilizer and UV stabilizer for polyvinyl chloride (PVC) | Added during PVC processing to prevent yellowing, embrittlement, and degradation of mechanical properties caused by UV exposure; typically used in combination with heat stabilizers. |
| Plastics Industry | UV stabilizer for engineering plastics | Used in injection molding or extrusion processes for engineering plastics such as polycarbonate (PC), polyamide (PA), and polyoxymethylene (POM) to enhance weather resistance and service life of finished products. |
| Rubber Industry | Antioxidant/antiozonant | Incorporated during vulcanization or compounding of synthetic rubbers (e.g., nitrile rubber, chloroprene rubber) to inhibit UV-induced photo-oxidative degradation and prevent surface cracking. |
| Coatings Industry | Weather resistance protection for coatings | Added to automotive coatings, industrial protective coatings, and wood finishes to prevent chalking, gloss loss, or delamination under outdoor UV exposure. |
| Polymer Recycling | Quality restoration of recycled materials | Added during pelletizing of post-consumer plastics—particularly PVC and polyolefins—to compensate for UV stabilizer depletion resulting from prior processing history and improve performance of recycled resins. |
| Fine Chemicals | Chemical synthesis intermediate | Serves as a benzotriazole-based intermediate for synthesizing other high-performance UV stabilizers or functional additives. |
