Applications:

Antioxidant 1790 is a high performance hindered phenolic antioxidant as primary antioxidant for organic polymers, especially suited for polyolefin ,polyurethane, polypropylene, polyester and polyamide fiber, also for other engineering plastics with high-temperature resistance, where it provides at low dosage. The performance benefit of Antioxidant 1790 includes the minimal color contribution, good solubility/migration balance and excellent compatibility with light stabilizer and secondary antioxidants,

Antioxidant 1790 has a high molecular weight, which results in low volatility and good extraction resistance. In molding applications it is particularly recommended for filled systems where extraction resistance is an issue. Its excellent gas-fade resistance is especially beneficial for polyurethane fibers. It can be used as well in polyolefin fibers.

Guidelines for use

The concentrations of Antioxidant 1790 to be used strongly depend on end-usen requirements.  

The recommended concentration is 0.05 ~ 0.25%.
