This solution establishes a specialized closed-loop underwater pelletizing and process water thermal management system engineered specifically for thermoplastic elastomers (TPE, TPU, TPV), polyolefin elastomers (POE), high-VA ethylene-vinyl acetate (EVA), and hot-melt pressure-sensitive adhesives. Integrating an enclosed underwater cutting chamber (Underwater Pelletizer), high-pressure bypass water piping, an inline centrifugal dewatering spin dryer (Underwater Pelletizing Dehydrator), and a dedicated closed-loop industrial refrigeration chiller (Industrial Chiller), it delivers instantaneous surface freezing and precision cutting for polymers that cannot be processed via traditional strand or water-ring cutting.<\/p>\n
Soft elastomers with low Shore hardness (< 85A), low melting points, or high tackiness present notorious processing challenges. When cut via strand pelletizers, elastomeric strands stretch like elastic rubber bands, break unevenly, wrap around feed rollers, or stick together in the cooling bath. In water-ring die-face systems, hot tacky melt smears across the die plate and fuses onto cutting blades, triggering catastrophic line shutdowns. By immersing high-speed rotating cutter blades directly against a thermally isolated die plate within a high-velocity chilled-water stream, this solution instantly freezes molten droplets into perfectly uniform micro-spheres or mini-pellets, preventing agglomeration and strand snapping.<\/p>\n","protected":false},"excerpt":{"rendered":"
