InTire & Conveyor Belts PVCmanufacturing, precise thermal control is essential for crosslinking efficiency, dimensional stability, splice strength, and long-run production consistency. In tire plants, published industry references show that finished automobile tires are typically vulcanized at145–160°C for about 10–15 minutes, while temperature control during final mixing is also critical to prevent premature scorch. In conveyor-belt production and repair, hot vulcanizing commonly operates at140–160°C under pressure, and continuousRotocurelines for belts and flat rubber goods use steam-heated drums at150–200°C, with reported belt-to-drum pressure around0.3 MPa, delivering high output, reliable curing, and reduced energy consumption. Within this demanding processing window,Eurotherm 330offers-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, responsive start-up, and flexible line changeovers.Eurotherm 320provides a dependable-30 to 320°Crange with9.8 mm²/s viscosity at 40°C, combining low-viscosity heat transfer, strong thermal stability, and cost-effective performance for mainstream curing and 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 manufacturers reduce downtime, simplify maintenance, and maintain stable continuous production.
