Product description
JY350 is one of the widely used high-temperature liquid phase
synthetic heat transfer oil, it can be applied in the temperature range of -7 ℃~350℃
and has the following important properties:
High thermal stability—— JY350 is a liquid phase heat transfer oil for use in high temperatures, which can provide reliable operation for years even at a use temperature of 350 ℃. In fact, JY350has passed the 350℃ thermal stability test.
Good user reputation——JY350is one of the widely used high-temperature liquid phase synthesis heat transfer oils, highly recognized by customers.
Reliability——JY350is performing well in thousands of large-scale devices around the world. It is important to note that when a heat transfer oil system fails, the production line must stop operating, so do not choose heat transfer oils with unproven reliability. For a service temperature above 310℃,JY350is your reliable choice.
Anti-fouling——JY350has good performance in preventing the formation of solid particles and coke, ensuring more reliable operation of the heat transfer oil system.

Scope of application
JY350It has been widely used in the industrial field, such as: chemical fiber industry; petrochemical industry; plastic industry; oil industry
