In the Rubber Industry, precise thermal management is essential for curing quality, dimensional stability, throughput, and long-run process reliability across extrusion, vulcanization, post-curing, and finishing operations. Industry references show that rubber vulcanization is commonly carried out at140–200°C, with many natural-rubber systems operating around150–180°C, while continuous liquid-curing methods for extruded goods may use hot baths at200–300°Cto accelerate heat transfer and shorten cure time. Steam autoclaves and heated tunnels also depend on stable thermal input to maintain pressure, temperature uniformity, and reproducible product quality for hoses, seals, belts, cables, and other rubber components. Within this demanding operating window,Eurotherm 330provides-49 to 315°Cservice,4.04 mm²/s viscosity at 40°C, and an ultra-low-68°C pour point, making it ideal for fast circulation, cold start-up, and flexible production changeovers.Eurotherm 320offers a dependable-30 to 320°Crange with9.8 mm²/s viscosity at 40°C, combining low-viscosity heat transfer, strong thermal stability, and cost-effectiveness for mainstream rubber heating 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 rubber manufacturers reduce maintenance, stabilize continuous operation, and improve batch-to-batch consistency.
