Blending and Coating Rubber Products in the Rollo Mixer
One of the most challenging mixing applications we encountered involved blending nitrile rubber with powder additives. The Rollo-Mixer’s dynamic mix action divides and combines these materials over 25 times per revolution while maintaining a uniform mixed product to down-line processing equipment. Not only do the two ingredients have a wide variance in particle size, but keeping them mixed while feeding the extruder is critical to producing a uniform TPE pellet. Many automotive parts like window and door seals are made from these versatile rubber pellets. Other applications include post-blending TPE pellets used to make rubber soles for the shoe and boot industry.
