Product function

LM-15A has the characteristics of high flash point, odorless, colorless, transparent and non-toxic to human body. It is used as a heat carrier in oil bath or thermostat in steel, glass, ceramics and other industries and scientific research.As a heat transfer medium, it is forced to circulate in the system to make it heated again and again, so as to meet the purpose of continuously obtaining the required heat energy for the heat demand equipment, and meet the requirements of the process temperature set in the production process and high-precision temperature control.

Product composition

LM-15A glacier coolant is modified by polysiloxane. Its appearance is colorless and transparent liquid, tasteless and insoluble in water.

Main parameter

14. Usage method
15. 1.LM-15A is used alone and cannot be mixed with other refrigerant and heat transfer media.
16. 2.Clean the system and add the solution to the system as soon as possible after confirming that there are no leakage points.
17. 3.It is recommended that the system be used in a closed manner, and nitrogen seal is allowed to prevent water from entering during use.

18. Instructions

19. At higher temperatures, LM-15A is sensitive to pollution caused by strong acids, alkalis, and some metal compounds and oxidants. These pollutants may accelerate the formation of volatile by-products. The oxidant can also increase the viscosity of the product. When these conditions may exist, it is recommended to regularly check the flash point of the product to monitor the operation safety. In addition, if the liquid smokes, there may be flammable conditions.
