Industrial Applications of Poly(dipropyleneglycol)phenyl phosphite
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Acts as an antioxidant and stabilizer to prevent oxidative degradation of polymers during processing and service life | Directly blended into the resin at 0.1–0.5% by weight during melt extrusion or injection molding of polyolefins, polyesters, polyurethanes, and other plastics |
| Rubber Industry | Enhances heat aging resistance of rubber products, extending service life | Incorporated together with the vulcanization system and other additives during rubber compounding, then uniformly dispersed in the compound via internal or open mixing |
| Coatings and Inks | Functions as a light stabilizer and antioxidant to improve coating weatherability and color retention | Co-mixed with resins, pigments, and additives in solvent-borne or powder coating formulations, followed by grinding and curing via spraying/baking |
| Synthetic Fibers | Improves thermal stability of polyester fibers during high-temperature spinning, minimizing yellowing | Added at 0.05–0.3% by weight and thoroughly mixed into dried polyester chips prior to melt spinning, ensuring uniform dispersion in the melt |
