UV ABSORBER HOSORB-234 is a high molecular weight ultraviolet light absorber (UVA)
of the hydroxyphenyl benzotriazole class. It has low volatility at high
temperatures and high resistance to thermal degradation for compounding and
molding applications. It is highly effective for polymers processed at high
temperature such as polycarbonate, polyester, polyacetal, PPO, polyamide, aromatic
copolymers, thermoplastic polyurethane and polyurethane fibers etc.. It is also
useful in the light stabilization of powder coatings and solvent-based coatings.
