Bis-2,2,6,6-tetramethylpiperidinol ester: A Powerful Light Stabilizer for Plastics and Polymers
Bis-2,2,6,6-tetramethylpiperidinol ester: A Powerful Light Stabilizer for Plastics and Polymers
Bis-2,2,6,6-tetramethylpiperidinol ester, commonly known as UV-770 or TINUVIN 770, is a highly effective light stabilizer used in the plastics and polymer industry. It is manufactured and supplied by INNO Specialty Chemicals, a leading chemical company based in China.
UV-770 belongs to the family of hindered amine light stabilizers (HALS), which are compounds that protect polymers and plastics from the harmful effects of UV radiation. HALS are widely used in the production of various plastic products, including films, fibers, and automotive parts, to prevent discoloration, brittleness, and cracking caused by exposure to sunlight.
UV-770 is a white crystalline powder that is insoluble in water but soluble in organic solvents such as methanol, ethanol, and chloroform. It has a molecular weight of 480.75 g/mol and a melting point of 77-81°C. UV-770 is compatible with a wide range of polymers, including polyethylene, polypropylene, polyvinyl chloride, and polystyrene.
One of the key advantages of UV-770 is its excellent thermal stability. It can withstand high temperatures during processing and storage, making it suitable for use in demanding applications such as automotive and outdoor products. UV-770 is also highly resistant to hydrolysis, which ensures its long-term effectiveness in protecting polymers from UV degradation.
UV-770 works by scavenging free radicals generated by UV radiation and converting them into stable molecules. This prevents the radical chain reaction that leads to polymer degradation and discoloration. UV-770 is particularly effective in protecting against the UVB range of sunlight, which is responsible for the majority of polymer degradation.
UV-770 is often used in combination with other light stabilizers to provide comprehensive protection against UV radiation. It is also used in conjunction with antioxidants and other additives to provide a complete package of protection against various forms of degradation.
UV-770 is a versatile light stabilizer that can be used in a wide range of applications. It is commonly used in the production of automotive parts, electrical appliances, packaging materials, and outdoor products. UV-770 is also used in the production of agricultural films, which protect crops from the harmful effects of UV radiation and extend their shelf life.
In conclusion, Bis-2,2,6,6-tetramethylpiperidinol ester, or UV-770, is a highly effective light stabilizer used in the plastics and polymer industry. It is manufactured and supplied by INNO Specialty Chemicals, a leading chemical company based in China. UV-770 provides excellent protection against UV radiation and is highly resistant to thermal and hydrolytic degradation. It is a versatile light stabilizer that can be used in a wide range of applications, making it an essential component in the production of high-quality plastic products.
