Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer and supplier of light stabilizer UV-328, also known as BASF Tinuvin 328. This ultraviolet absorber is widely used in various industries to protect polymers and plastics from UV radiation and prevent degradation caused by exposure to sunlight.

Chemical Properties of Light Stabilizer UV-328

UV-328 belongs to the class of benzotriazole UV absorbers and has the chemical formula C26H35N3O. It is a white or light yellow powder with a melting point of 80-83°C and a boiling point of 584.4°C at 760 mmHg. The molecular weight of UV-328 is 405.58 g/mol, and its density is 1.12 g/cm3 at 20°C.

UV-328 is soluble in organic solvents such as acetone, methanol, and ethyl acetate, but insoluble in water. It has good compatibility with various polymers and plastics, including polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polyurethane.

The main function of UV-328 is to absorb UV radiation in the range of 290-400 nm, which is the most harmful to polymers and plastics. UV-328 works by converting UV energy into heat, which dissipates from the polymer matrix and prevents the formation of free radicals that cause degradation.

Market Prospect of Light Stabilizer UV-328

The demand for light stabilizers and UV absorbers is growing rapidly due to the increasing use of polymers and plastics in various applications such as packaging, construction, automotive, and electronics.
