AQUACER® 531 is a wax emulsion used as an anti-caking additive for thermoplastics and hot-melt adhesives. Thermoplastic granulated material (TPE, TPU, EVA) tends to compact and cake under pressure and heat. AQUACER® 531 is used in the underwater pelletizing of such materials and forms a protective layer covering the granules, thereby generating non-sticking and free-flowing granulated materials. Unlike the commonly performed dusting of the granulate materials with solid release agents (chalk, talc), significantly lower quantities are needed, which, therefore, avoid impact on the properties of the thermoplastic material. The generation of dust during processing is also eliminated.
