Special white masterbatches with the trade name SuperWhite® are specifically designed for the manufacturing of engineering polymeric products with unique properties, particular requirements and sensitive process conditions. Using these masterbatches, in addition to bring whiteness and full opacity in final products, have positive influence on thermal stability and durability of the product especially in high speed extrusion of thin films. In the following, some of the most important white masterbatches for engineering product are described:

• In the production of very thin Polyethylene cast film, SuperWhite® series white masterbatches can be resistant to the high temperatures of the production process (over 280-300 °C). Beside the high temperature extrusion process, PE thin films are made through high speed processing conditions (production of film at a speed of 500 meters per minute or more) in thicknesses of less than 10 microns.
• In the injection molding of polymer preforms, especially PET, the unique combination of white masterbatch allows creating a complete opacity and reduces the injection cycle time of the preform, which makes high added value in the continuous injection process of PET preforms for packaging of different types of drinks and dairy products.
• In the production of PE blown thin films and wrappers with a high speed production process (High speed film blowing ) as well as the production of multilayer laminated films (lamination and extrusion coating), SuperWhite masterbatches have excellent compatibility as well as fast dispersibility in a short time extrusion processing conditions.
