In the global light stabilizer market, hindered amine light stabilizers (HALS) occupy the most important market share. HALS are effective additives used in a wide range of industries. They protect polymer materials from UV-induced degradation by scavenging free radicals generated by UV radiation. HALS help to extend the service life of polymer materials, so as to provide people with better quality products.
HALS are able to inhibit the photoaging process of polymers in several ways. First, they break down hydroperoxides (ROOH) and convert them into harmless substances. Secondly, HALS have strong free radical capture ability, which can neutralize and stabilize free radicals and prevent free radical-induced polymer chain breaking reactions. In addition, HALS have regenerative capabilities, i.e., they are able to regain their own stability after a free radical trapping reaction and thus continue to function.
We have developed a range of HALS to meet the requirements of a variety of markets and applications. Please contact us today if you have a requirement.
