The efficacy of polymer additives is often defined by their ability to remain in place and continue their protective function over extended periods. For light stabilizers, particularly those exposed to harsh environmental conditions, low volatility and minimal migration are paramount. These characteristics are key to ensuring consistent performance and preventing issues like surface blooming or loss of protective properties. NINGBO INNO PHARMCHEM CO.,LTD. highlights the advantages of incorporating such advanced additives into polymer formulations.

Polymer degradation caused by UV radiation is a significant challenge across numerous industries, from automotive and construction to packaging and textiles. Hindered Amine Light Stabilizers (HALS) are a vital solution, working by intercepting free radicals generated during the photodegradation process. However, the effectiveness and longevity of these stabilizers are heavily influenced by their physical properties, specifically their volatility and tendency to migrate within the polymer matrix.

Low volatility refers to an additive's resistance to evaporating or sublimating at processing temperatures or during the product's service life. High volatility can lead to a loss of the stabilizer over time, diminishing its protective effect and potentially causing surface issues or emissions. High molecular weight polymeric HALS, such as HALS 622, are inherently designed with low volatility due to their larger molecular size. This ensures that the stabilizer remains within the polymer, providing continuous protection against UV degradation.

Minimal migration is equally important. Migration refers to the movement of an additive from within the polymer matrix to the surface (blooming) or to an adjacent material. This can lead to surface defects, reduced effectiveness, and potential contamination of other materials. HALS with high molecular weight and a polymeric structure, like HALS 622, exhibit significantly reduced migration. This is especially critical in applications involving contact with other materials, such as in multi-layer films or coatings, or in sensitive environments like food packaging, where migration is strictly regulated.

The benefits of low volatility and minimal migration are directly translatable into enhanced product performance and extended service life. By ensuring the stabilizer remains concentrated within the polymer, manufacturers can guarantee that their products will withstand UV exposure for longer periods without compromising their physical properties, color, or appearance. This reliability builds customer trust and reduces the need for premature product replacement.

At NINGBO INNO PHARMCHEM CO.,LTD., we understand these critical performance requirements. Our portfolio includes advanced HALS, such as HALS 622, which are engineered to deliver superior protection through their inherently low volatility and minimal migration characteristics.
