UV ABSORBER HOSORB-UV360 is a highly effective ultraviolet light absorber with strong absorbance in the 300-400nm region. It provides excellent compatibility and low volatility.
It is particularly suitable for processing and aging conditions where high temperature, low volatility and good compatibility are required, such as complex molding, fibers, sheets, laminated or coextruded semi-finished parts.It is suitable for PE, PP, PC, POM, PVC, PA, PE, PU, ABS resin, elastomer, adhesive etc. The synergism can be realized when it is combined to use with HALS or antioxidant.
