LM-15 series catalogue reference values (Table 13)

Model	Temperature range (°C)	Viscosity (cP)	Density (g/cm³)	Specific heat (cal/g·°C)	Thermal conductivity (W/m·K)	Flash point (°C)
LM-15A	−70 to +180	5.63	0.919	0.418 cal/(g·°C) = 1.75 kJ/(kg·K)	0.126	80
LM-15B	−50 to +200	10.40	0.942	0.407 cal/(g·°C) = 1.70 kJ/(kg·K)	0.136	148
LM-15C	−30 to +200	21.71	0.953	0.420 cal/(g·°C) = 1.76 kJ/(kg·K)	0.145	170

All properties are printed at 20°C. The catalogue lists no freezing point for this series; the temperature range is the operating envelope, not a freezing point.

Reference values from the Chaoyang Guangda LM catalogue — typical figures rather than guaranteed limits. Confirm the exact model and concentration on the current model TDS before specifying.

Before you specify

Flash points vary by model. Clean and dry the system, use the fluid directly and prevent moisture ingress. Mixing with other secondary refrigerants is prohibited.

FROM FORMULATION TO APPLICATION

Precision temperature control, beyond refrigeration.

The polysiloxane-based LM-15 references describe heat-carrier use in oil baths and thermostatic systems for steel, glass, ceramics and scientific research.

01 / APPLICATION NOTE

Consider the complete duty cycle

Discuss startup viscosity, heat demand and temperature-control precision as well as the maximum process temperature. The catalogue lists separate LM-15A, B and C operating windows.

02 / APPLICATION NOTE

Check non-metallic materials

The original product page includes temperature-dependent properties and a non-metal compatibility table. Request a current compatibility assessment for the seals, hoses and polymers in your system.

About these product references

Application notes are adapted from Glacier’s original product information. Unless a table states otherwise, numeric specifications follow the supplied catalogue. For the confirmed specification, obtain the current model-specific TDS and SDS. Links below point to the original source pages, not new technical documents.
