The wet-grind system produces a premium fine rubber powder with special surface characteristics that meet the demanding specifications of such industries as automotive, sealants, specialty coatings and membranes and custom compounding. The surface characteristics and shape of the particles produced with this system enable the product to be more successfully integrated into other polymer materials.
