LC49 Thermal Management Fluid

Features Of LC49 Thermal Management Fluid

1. Non-toxic, non-corrosive formulation suitable for long-term exposure to aluminum, copper, and stainless steel components.

2. Low volatility and high thermal stability (decomposition onset > 280 °C) enabling reliable operation in extended temperature cycles.

3. Zero ozone depletion potential (ODP = 0) and negligible global warming potential (GWP < 10), compliant with evolving environmental regulations.

4. Excellent dielectric properties (dielectric strength > 35 kV/mm at 25 °C), certified for use in direct-contact EV battery cooling systems.

5. Hydrolytically stable with minimal acid number drift (< 0.02 mg KOH/g after 1000 hrs at 120 °C), ensuring consistent system integrity.

Typical Applications Of LC49 Thermal Management Fluid

1. Direct-die cooling of high-power IGBT modules and SiC inverters in electric vehicle powertrains.

2. Thermal management loops for lithium-ion battery packs in automotive and energy storage systems (ESS).

3. Coolant in liquid cold plates for AI accelerator GPUs and high-density data center server racks.

4. Heat transfer fluid in low-temperature industrial process chillers requiring non-freezing, non-flammable performance.

5. Primary coolant in two-phase immersion cooling systems for edge computing hardware.

LC49 Thermal Management Fluid – Frequently Asked Questions (FAQ)

Q1: What is the CAS Registry Number for LC49 Thermal Management Fluid?

A: The CAS Number for LC49 Thermal Management Fluid is 2731225-87-1. This identifier applies to the commercial formulation as supplied; individual components are listed separately in the Safety Data Sheet (SDS Section 3).

Q2: Can LC49 be mixed with other heat transfer fluids such as ethylene glycol or mineral oil?

A: No — LC49 is chemically immiscible with glycols, hydrocarbons, and silicone oils. Mixing may cause phase separation, reduced thermal performance, and unpredictable material compatibility. Always flush systems thoroughly before switching to LC49.

Q3: Does LC49 require special handling during system fill or maintenance to prevent moisture ingress?

A: Yes — although hydrolytically stable, LC49 is hygroscopic at elevated humidity. Use closed-loop filling equipment with dew point control ≤ –40 °C, and maintain sealed storage under nitrogen blanket. Moisture content should remain < 50 ppm (Karl Fischer ASTM D6304) for optimal longevity.

Q4: Is LC49 approved for use in UL-listed battery energy storage systems (BESS)?

A: Yes — LC49 is included in UL 9540A test reports for multiple Tier-1 BESS integrators and is referenced in UL 1973 Annex H for non-aqueous coolants. Full system-level listing remains the responsibility of the end-equipment manufacturer.

Q5: Has LC49 been evaluated for extractables and leachables in contact with fluoropolymer tubing (e.g., FEP, PFA)?

A: Yes — per USP <87> and <88> cytotoxicity testing, LC49 shows no detectable extractables from FEP/PFA tubing after 168 hrs at 85 °C. GC-MS analysis confirms < 0.5 µg/cm² total organic extractables, well below ICH Q5E thresholds.
