Ningbo Inno Pharmchem Co.,Ltd is one of the leading manufacturers of light stabilizer 765, also known as BASF light stabilizer Tinuvin 292. This UV absorber is widely used in various industries, including plastics, coatings, and adhesives, to enhance the performance of the products. In this article, we will discuss the chemical properties, application, and market prospects of light stabilizer 765.

Chemical Properties

Light stabilizer 765 is a bis(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate, also known as bis(1,2,2,6,6-pentylmethyl-4-piperidinyl) sebacate or bis(1,2,2,6,6-Pentamethylpiperidinyl)-sebacate. It belongs to the family of hindered amine light stabilizers (HALS), which are widely used in the polymer industry for their excellent UV resistance properties.

The chemical structure of light stabilizer 765 allows it to absorb UV radiation and convert it into harmless heat, thus protecting the polymer from photo-degradation. It is a white or light yellow powder with a melting point of 50-54°C and a boiling point of 593.4°C at 760 mmHg.

Application

Light stabilizer 765 is a versatile UV absorber that can be used in various polymers, including polyolefins, PVC, polyurethane, and polyester. It is particularly useful in outdoor applications, where the polymers are exposed to sunlight for extended periods. The addition of light stabilizer 765 to the polymer matrix enhances its resistance to UV radiation, thus preventing yellowing, cracking, and loss of physical properties.

In the plastics industry, light stabilizer 765 is used in the production of films, fibers, and molded parts, such as automotive components, electrical enclosures, and outdoor furniture. It is also used in the production of coatings, such as automotive paints, architectural coatings, and wood coatings, to enhance their durability and color retention.

In addition to its UV resistance properties, light stabilizer 765 also has antioxidant properties, which make it an excellent choice for applications that require both UV and thermal stability. It is compatible with other stabilizers, such as hindered phenols and phosphites, to provide comprehensive protection to the polymer.

Market Prospects

The global market for light stabilizers is expected to grow at a CAGR of 6.5% from 2020 to 2025, driven by the increasing demand for UV-resistant polymers in various industries. The Asia-Pacific region is the largest market for light stabilizers, with China being the largest consumer and producer of these additives.
