Synthetic hydrocarbons (mfr. LM-16D product description, 2025)
| Model | Temperature range (°C) | Viscosity (cP) | Density (g/cm³) | Specific heat (cal/g·°C) | Thermal conductivity (W/m·K) |
|---|---|---|---|---|---|
| LM-16A | +20 to +280 | 85.39 | 0.88–0.92 | 0.478 cal/(g·°C) = 2.00 kJ/(kg·K) | 0.143 |
| LM-16B | +10 to +320 | 36.28 | 0.99–1.03 | 0.411 cal/(g·°C) = 1.72 kJ/(kg·K) | 0.123 |
| LM-16C | −30 to +340 | 5.75 | 0.98–1.01 | 0.389 cal/(g·°C) = 1.63 kJ/(kg·K) | 0.131 |
All properties are printed at 20°C. The catalogue states flash points above +120°C for this series and gives no per-model freezing point. For LM-16D the manufacturer's own product description states an open-cup flash point of not less than +207°C.
| Temperature (°C) | Density (g/cm³) | Dynamic viscosity (cP) | Specific heat (kJ/kg·K) | Thermal conductivity (W/m·K) |
|---|---|---|---|---|
| 20 | 1.046 | 45 | 1.5949 | 0.1455 |
| 50 | 1.021 | 10.5 | 1.6869 | 0.1420 |
| 100 | 0.986 | 3.0 | 1.8251 | 0.1397 |
| 200 | 0.916 | 0.68 | 2.1307 | 0.1269 |
| 300 | 0.846 | 0.29 | 2.4279 | 0.1106 |
| 350 | 0.805 | 0.20 | 2.5786 | 0.1013 |
Reference values from the manufacturer's LM-16D product description, not from the catalogue. LM-16D: use range +20 to +350°C, open-cup flash point not less than +207°C, average boiling point +370°C, pour point ≤−30°C, density at 20°C 1.046 ± 0.003 g/cm³. Closed-loop systems only.
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.
View source: catalogue p.27 (PDF p.31)Operating limits require model-specific system design. The manufacturer specifies closed-loop systems only. Prevent moisture ingress and obtain the current SDS and approved technical specification before commissioning. The manufacturer states that where LM-16D is used for indirect heating in food or drug production, the relevant national food and drug safety standards must be met — this is a condition of use, not an approval.
FROM FORMULATION TO APPLICATION
LM-16 references describe synthetic-hydrocarbon heat-transfer media for pharmaceutical, chemical, solar-thermal, oil and gas applications.
A, B, C and D grades have different operating windows. The catalogue covers A, B and C; LM-16D comes from the manufacturer's own product description and runs to +350°C. Review startup conditions, process temperature and equipment limitations rather than applying a family maximum to every grade.
The source references call for cleaning and drying before filling and recommend a closed system. Discuss moisture exclusion, ventilation and safe handling with the technical team.

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.
