Profile: M.G. Polyblends is an ISO 9001:2000 certified company, engaged in production of color masterbatches and additive masterbatches. We offer black masterbatches, white masterbatches, color masterbatches, special effects masterbatches, additive masterbatches and wax base masterbatches. White masterbatch provides whiteness, brightness and opacity to the final product. A variety of chemicals such as titanium dioxide, antimony oxide, zinc oxide and zinc sulphide are used to provide these properties in plastics. Some of the main reasons for use of titanium dioxide are for its special properties such as average particle size (.19 to 0.22 micron) and high refractive index.
