In the Reclaimed Rubber industry, precise thermal control is essential for balancing devulcanization efficiency, polymer preservation, throughput, and final compound consistency. Modern reclaiming processes span both batch and continuous routes: industrial autoclave devulcanization has been reported at an initial28–30 bar, rising to40 barand about225°Cfor roughly2.5 hours, while continuous thermo-mechanical devulcanization systems emphasize rapid processing, with conversion completed inless than 2 minutesand energy use reported atbelow 350 kWh per ton. These demanding conditions require heat-transfer fluids that start quickly, circulate efficiently, and remain stable through repeated heating cycles.Eurotherm 330provides a broad-49 to 315°Cservice range,4.04 mm²/s viscosity at 40°C, and an ultra-low-68°C pour point, making it ideal for cold starts, responsive circulation, and flexible production changeovers.Eurotherm 320offers a dependable-30 to 320°Coperating range with9.8 mm²/s viscosity at 40°C, delivering low-viscosity heat transfer, strong thermal stability, and cost-effective performance for mainstream reclaiming and refining loops. For larger closed systems,RÜTGERS Ruetaflex 1000extends coverage to-55 to 330°Cwith6 mm²/s viscosity at 40°C, low-pour-point fluidity, and long service life, helping reclaimed-rubber plants reduce downtime, simplify maintenance, and sustain stable continuous operation.
