Characteristics and Uses
UV320 is a high-efficient light stabilizer , widely apply to in the plastics and other organic matter, including unsaturated polyester, PVC, PVC plasticizing glue, etc. It has better effect when applied to in the polyurethane, polyamnamee, synthetic fibers especially those polyester and epoxy resins. UV320 has strong ultraviolet absorbtion ability and low volatility characteristics. It can effectually protect the polyester and the organic colouring avoname ultraviolet radiation, thus protect the primitive physics appearances of the shaping object, films, etc. which under the open-air state.The color of the UV320's is lighter than general ultraviolet absorbers.
