Examples: PET cast and blown films, pipes, tubes, wire and cables, blow molding and general extrusion.

Mode of action and advantages: ADD-MAX® 804 contains a highly effective additive, which lowers the apparent viscosity of the polymer melt during processing. It reduces the friction between the polymer melt and internal metal surface of the processing equipment which is helpful to increase the production efficiency. Based on existing experience, ADD-MAX® 804 will not influence the mechanical properties of end-products, e.g. tensile strength and impact.

Advantages: Reduction or elimination of die build-up; Reduction of melt-fracture phenomenon; Potentially higher throughputs can be achieved when capacity is available (10% - 30%). For blow molding: reduction of cycle time; Lower extrusion temperature, reduction of energy consumption; Reduction in surface defects and improvement of surface properties (gloss and appearance); Improved gauge control, reduced melt-orientation, die-swell and melt-pressure; Faster color changes, reduction of waste and less production interruptions; Keeping-clean the metal surfaces of the extruder, die and filters, less “black spots“ in final product; No blooming will appear on the surface of extruded parts; no change in printing and heat-sealing properties; Non-sticking pellets, dust free dosing; Safe and easy handling.
