Chemical name: 2-(2'-Hydroxy-5'-methylphenyl)-benzotriazole

• CASNO:2440-22-4
• Introduction:

UV-P is a benzotriazole type UV absorber. It has a high absorption in the wavelength

of 270~340nm. It is also efficient for the light stabilization of polyvinyl chloride, unsaturated

polyurethane, polystyrene, coatings and lacquers.

• Specification:
  • Appearance: white to yellowish crystal powder
  • Melting Point: 128~131℃
  • Content (HPLC) : 99% Min.
  • Transmittance: 440nm≥98%   500nm≥99%
  • Ash: 0.1% Max.
  • Volatiles: 0.5% Max.
• Property:
  • Odorless, don’t bring smell to polymers.
  • Insensitive to metal ion
  • Non-flammable, non-explosion, non-toxic, harmless to health.
  • Very high photo stability for its strong ability to absorb light especially in UV region (270~340nm)
  • Very stable to heat and can be used in plastic which require high processing temperature.
• Toxicity & Safety

      UV-P can be handled as an industrial chemical provided the following handing precautions

are strictly observed: a) Wear gloves to avoid contacting with skin. 

                                  b) Maintain a clean and well-ventilated working area

                                 c) Wear glasses and face mask whenever dust is unavoidable to prevent irritation to the eyes and respiratory tract.

•  Package: 20kg or 25kg PE bags or cartons with pallet.

•  Storage: UV-P should be stored in a closed system and be kept in a dry and dark place  without any light exposure.
