It can almost entirely absorb the ultraviolet radiation in the range 300-330. The polyurethane is easy to degrade due to the radiation of this wave range. So it has excellent light stability for the polyurethane products like flexible foam, rigid foam, elastomer, artificial leather, adhesive and coating etc. It prevents the aging and improves the color stability to prolong the service life of the products.
