Molecular Structure, Advantages and Disadvantages of Light Stabilizer 788

Tiangang Auxiliary is an enterprise focused on the plastic-additives field, and light stabilizer 788 is one of its main products. Light stabilizer 788 is a polymeric hindered-amine light stabilizer whose chemical name is a mixture of a polymer of {[(6-(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl], [(2,2,6,6-tetramethyl-4-piperidyl)imino]} and a tetramethylpiperidine-4-ethanol dimethylsuccinate copolymer.

The molecular structure of light stabilizer 788 is unique; its polymeric structure gives it very low volatility at high processing temperatures, low extractability and low migration in polymers. In addition, light stabilizer 788 has significant light-stabilizing effects, providing long-term thermal and light stability for various polymers. Its mechanism is the same as that of hindered phenols: it captures free radicals to suppress polymerization reactions, thereby extending the service life of polymers.

However, light stabilizer 788 also has some disadvantages. First, it has no negative effect on the initial coloration of the substrate, which means it may affect the color of the polymer during use. Second, the addition level of light stabilizer 788 is relatively high, which may affect the processing performance and mechanical properties of the polymer. In addition, its easy flow may affect its dispersion in the polymer, thereby affecting stability.

To overcome these problems, Tiangang Auxiliary has taken a series of measures. First, the company continuously improves production processes to reduce the addition level of light stabilizer 788, thereby reducing its impact on polymer properties. Second, the company strengthens the dispersion treatment of light stabilizer 788 in polymers, improving its stability. Finally, the company keeps developing new products to provide better solutions.

In summary, light stabilizer 788 is a plastic additive with excellent performance; its unique molecular structure gives it significant light-stabilizing effects and thermal stability. However, it also has some disadvantages that require continuous improvement and optimization. As an enterprise focused on the plastic-additives field, Tiangang Auxiliary will keep innovating and progressing to provide customers with higher-quality products and services.
