Continuous Innovation: Beijing Tiangang's New-Generation Light Stabilizer Wins the Ringier Technology Innovation Award Again

At the same time, Tiangang® HS-950 also boasts excellent compatibility with resins and outstanding extraction resistance, making it especially suitable for application scenarios requiring low migration, low blooming and particularly long service life. Based on these performance advantages, this upgraded light stabilizer is not only widely used in thick products such as injection molding, rotational molding and hollow molding, but also especially suitable for thin products such as films, tapes and fibers.

As everyone knows, solar energy is a clean and safe renewable energy source. If solar energy could be efficiently utilized, it would undoubtedly be a boon for all humanity. In our daily lives, we occasionally see very large arrays of solar photovoltaic panels installed on open land. However, these panels can be placed not only on the ground but also on water bodies such as oceans and lakes.

Such floating photovoltaic systems (Figure 1) require floats to support the PV modules. The weather resistance of these float materials determines the service life of the floats, which in turn affects the service life of the floating PV system.

Tiangang® HS-950 is a hindered amine light stabilizer that can be used for floating PV floats, and compared with the traditional grade 2020 light stabilizer, it can more significantly improve the weather resistance of the material. In practical applications, depending on the float material and the service environment, Tiangang® HS-950 can extend the service life of floats from 3-5 years to 10-20 years.

Many leisure venues and stadiums use artificial turf (Figure 2), whose common materials include PP, PE and PA. Long-term sunlight exposure, especially ultraviolet radiation, breaks down the molecular chains of these materials, causing turf fibers to crack, fade and even powder, while hindered amine light stabilizers have made outstanding contributions to improving the light-aging and thermo-oxidative aging resistance of artificial grass.

The high-molecular-weight polymeric hindered amine light stabilizer upgrade product launched by Beijing Tiangang this time — Tiangang® HS-950 has undergone special molecular structure design optimization, and a higher effective nitrogen content, meaning it can more effectively inhibit the degradation of polymer molecular chains, therebybringing longer-lasting light-aging and thermo-oxidative aging performance to thin products such as artificial grass, and effectively ensuring a service life of more than 5 years for artificial grass fibers.

It is worth mentioning that artificial grass often comes into contact with acidic substances during use, such as brominated flame retardants, acidic detergents and disinfectants, and acidic substances contained in infill rubber granules. These acidic substances consume hindered amine light stabilizers, causing the light stability of plastic products to decline. In response, Beijing Tiangang has specially launched the acid-resistant high-molecular-weight hindered amine light stabilizer — Tiangang® HS-625. This product has low reactivity with acidic substances, and can effectively solve the weather-resistance problem of artificial grass in acidic environments. Thanks to its outstanding performance and innovativeness, Tiangang® HS-625 has won multiple provincial and ministerial-level as well as industry science and technology progress awards.

Success does not come overnight. The reason Beijing Tiangang has been able to develop such an industry-benchmark product is that the company has long been committed to the serialized R&D and innovation of light stabilizer products resistant to acid, high temperature and high ultraviolet radiation. In addition to Tiangang® HS-625, grades such as Tiangang® T-68, Tiangang® T-69 and Tiangang® XT-8 are available for customers in different fields.
