Light Stabilizer for Polyester

With the wide application of transparent FRP, preventing its aging and prolonging its service life has become an important issue. Among the factors that affect the aging of FRP, ultraviolet rays in sunlight are one of the main external causes. After FRP is irradiated by sunlight, it causes photochemistry. The reaction is photo-oxygen aging. In order to prevent and inhibit the occurrence and development of photo-oxygen aging, and to extend the outdoor service life of materials or products, it is necessary to add an appropriate amount of light stabilizer to the material.
