          GRANDSORB UV ABSORBERS



          The polymeric substrates under the long-term exposure of UV lights shall easily be degraded and damaged, with the synergetic effects of oxygen and water vapors, etc. Such effects would not only disfeature the appearance of the polymers, but also would bring harmful damages on the physical and chemical properties of the substrates, and furthermore reduce the substrates’ working life.
