Profile: M. G. Polyblends is engaged in the production of color master batches and additive master batches. We are an ISO 9001:2000 certified company. Our products include black master batches, white master batches, color master batches, additive master batches, and rotofoam master batches. Optical brighteners are based on bisbenzoxazole type organic derivative dispersed in poly-olefinic polymer. These master batches are added in polymers to reduce yellowing, to give improved whiteness, and to enhance the brightness of a product. These master batches function by absorbing the ultraviolet radiation and re-emitting the blue light. Our UV master batches are based on hindered amine light stabilizer, which is properly dispersed in a poly-olefin carrier. They also offer weather ability characteristics to molded items for outdoor applications, irrigation pipes, automobile components, crates, films, rotomolded tanks, and garden chairs.
