Description
Tinuvin 327 is a superior benzotriazole UV absorber. Its absorption wavelength range is greater than the ultraviolet absorber UV-P. It can strongly absorb ultraviolet rays of 300-400 mm, and the highest absorption peak is 353 nm. Tinuvin 327 is soluble in styrene, benzene, toluene and other solvents, slightly soluble in alcohol and ketone, and insoluble in water. Tinuvin 327 has greater solubility in solvents and plasticizers such as benzene, toluene, styrene, methyl methacrylate, and cyclohexane. It is an excellent light stabilizer, which has a good synergistic effect when used in combination with an antioxidant. Tinuvin 327 has good chemical stability, low volatility, good compatibility with polyolefins and resins, high processing temperature resistance, good color fixing, and excellent washing resistance. Tinuvin 327 is suitable for polyacetal, polyurethane, unsaturated polyester, polyethylene (PE), polypropylene (PP), polyolefin, polyvinyl chloride (PVC), natural rubber, synthetic rubber, latex, paint, polymethacrylic acid methyl ester and ABS resin, especially suitable for polypropylene fiber. Tinuvin 327 has significant synergistic effects when used in combination with antioxidants, especially DLTDP.
Recommended dosage
0.1-0.3%
Advantages
Tinuvin 327 has high temperature resistance and good thermal stability, and can be used for plastic products that require high temperature processing.
Tinuvin 327 is not sensitive to metal ions.
