LM-6 series catalogue reference values (Table 8)

Model	Temperature range (°C)	Freezing point (°C)	Boiling point (°C)	Flash point (°C)	Viscosity (cP)	Density (g/cm³)	Specific heat (cal/g·°C)	Thermal conductivity (W/m·K)
LM-6	−130 to +30	−142	>+70	−25	0.50	0.750	0.430 cal/(g·°C) = 1.80 kJ/(kg·K)	0.120
LM-6A	−100 to ambient	−111	>+120	+16	0.80	0.771	0.431 cal/(g·°C) = 1.80 kJ/(kg·K)	0.118

All properties are printed at 20°C. The catalogue carries two figures for LM-6B: a −145 to −100°C table entry and a −140 to +30°C statement for the series. Its operating limit requires written manufacturer clarification.

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

Flammable hazardous chemicals. LM-6B temperature statements differ within the catalogue, so its operating limit requires written clarification. Do not dilute or mix with other fluids.
