Owing to its high energy value, UV radiation can destroy polymers in a very short time – particularly when acting in conjunction with harmful environmental factors. Surfaces become matt and form chalky deposits, with cracks and decomposition following. Masterbatches by LUVOBATCH® offer a number of solutions that can be adjusted to coordinate with each other in order to combat this problem: UV absorbers, HALS (hindered amine light stabilizers) and quenchers. The absorbers filter the harmful components of light and transform them into heat. HALS prevent the reactions of photoxidation products such as peroxides and radicals on surfaces and in deeper layers. Quenchers deactivate the harmful radicals.
