Description

Longevity of a polymer based product greatly depends on base polymer as well as additives inside the product to extend the life of the product. Various chemical molecules are being used in rubber products to fight against UV rays in sunlight to improve life of the product. The mechanism of each UV stabilizer varies depends on the chemical molecules in the stabilizer.

One kind of chemical molecules are able to absorb UV rays and be able to convert to infra-red rays or to energy. Examples of this type of chemical molecules are carbon black, Hydroxybezophenones,hydroxyphenylbenzotriazole, oxanilides for polyamides, benzophenones, benzotriazoles and hydroxyphenyltriazines.

Another kind of UV stabilization is through Hindered amine Light stabilizers(HALS). The mechanism of UV stability is offered to the product the free radical scavenging capability of HALS and thus limiting the degradation of material caused by UV radiation.The chemical reaction involved in the process of HALS stabilization explained in Denisov Cycle.

The usage one kind of chemical molecule might result in limited longevity extension of the products. PS LLC, has unique combinations of various chemical molecules under G-UVL package with LDPE, LLDPE or EVA carriers.
