Ultra Violet Stabilizer Masterbatch

Ultraviolet included in sunlight causes the “Photo Oxidation Process” while a polymer is absorbing the Ultraviolet. The sudden electronic transitions in a polymer matrix initiated by the Ultraviolet lead to volatile state of polymer molecular. The Photo Oxidation reduces the polymer’s molecular weight, and consequently makes the polymer matrix more brittle.

With respect to your polymer types, other fillers and their expected service life, your polymers directly exposed to sunlight have to be treated by proper UV Absorbers curbing free radicals so as to effectively protect your final plastics’ durability and visual clear appearance. We are providing our customers with the most effective UV absorbers suitable for your final products.
