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. The Rollo-Mixer is a reliable workhorse applications include post-blending thermoplastics used in hundreds of everyday products. Automotive parts like window and door seals are made from these versatile rubber pellets.

Thermoplastics are physical mix of polymers (plastic powders and a rubber) which are engineered to perform with the rigidity of plastics and the elasticity of rubber. Global leading manufacturers use Rollo-Mixers for blending thermoplastics for an even dispersion of their extruded pellets. TPE pellets become flexible hoses, cable, toothbrushes, insoles for shoes, snowmobile skis and much more. Crumb rubber is also blended and/or treated in our industrial rubber mixers for use on synthetic sports fields.
