What is the difference between heat transfer oil, dimethyl silicone oil and ethylene glycol as oil bath medium?
Heat transfer oil is the cheapest, but it smells unpleasant when heated, and if it is used in industry for a long time, it will cause pipeline blockage, and a lot of tar generated is difficult to handle; dimethyl silicone oil is good, but it is expensive; B Diols are generally used as antifreeze! Polyethylene glycol is used as oil bath medium!
