InAutomotive Component Performance Testing, precise thermal control is essential for simulating harsh environmental conditions, validating durability, and ensuring repeatable results across rapid heating and cooling cycles. Test platforms, refrigerated circulators, oil baths, and component rigs require heat transfer fluids that combine low-temperature pumpability, thermal stability, and dependable circulation under continuous cycling.E200offers an operating range of-85 to 230°C,1.20 mm²/s viscosity at 40°C, and apour point below -85°C, making it well suited to extreme cold-start simulation and fast-response thermal cycling.E230, with a range of-60 to 230°Cand1.90 mm²/s viscosity at 25°C, provides strong low-temperature fluidity and long service life for routine environmental testing and controlled durability programs. For broader integrated test windows, silicone-basedSi-05covers-80 to 280°Cwith4.0 mm²/s at 40°Cand aflash point of 128°C, whileSi-10extends to-60 to 300°Cwith7.9 mm²/s at 40°Cand a210°C flash point, supporting wider thermal swings and stable long-duration operation. Together,E200 / E230 / Si-05 / Si-10help automotive testing facilities improve control accuracy, reduce thermal stress on systems, and accelerate reliable component validation with greater process safety and efficiency
