Product Introduction

  1. 2 4-Dihydroxybenzophenone: Uv absorbing is a light stabilizer that can take in the ultraviolet part of sunlight as well as fluorescent sources without changing itself. Plastics as well as other polymer materials under sunlight as well as fluorescence, due to the action of ultraviolet light, automatic oxidation response, resulting in deterioration and wear and tear of the polymer, to ensure that the look and mechanical properties become worse.
  2. Including UV absorbent can selectively absorb the high energy of the UV, to make sure that it comes to be safe power and also launched or eaten.
  3. Because of the different types of polymer, the ultraviolet wavelength of its wear and tear is not the same, different ultraviolet absorbers can absorb different wavelengths of ultraviolet, when used, ought to be selected according to the type of polymer ultraviolet absorbers.

Zhi Shang Chemical is committed to the production of high-quality 2 4-Dihydroxybenzophenone a first-class production line to ensure a stable supply of products to meet the needs of different markets.
