    Polymer Thermal Conductivity Measurement

    C-Therm has provided a breakthrough in the characterization of critical performance attributes of conductive polymers used in electronics and automotive industries. The main advantage the technique offers is the flexibility to test a wide range of sample geometries. As an example, clients at a large polymer producer use the test samples from their tensile testing regimen to also test the in-plane and through-plane thermal conductivity with the C-Therm modified transient plane source (MTPS) sensor. There is no longer the need to destructively machine or form specific sample sizes/dimensions to test thermal conductivity.


    From Explosives to Ink Toners

    The C-Therm MTPS sensor is being used to safely test the stability, degradation, and shelf life of explosives because it is the only instrument engineered for evaluating the thermal conductivity of powders safely. Sample volumes are as small as 1.25 ml. This is also critical to a rapidly growing client base in metal hydrides, where materials are expensive and available in low quantities. The technology is also migratable to manufacturing environments as a cost-effective way to monitor powder processes for moisture and homogeneity.


    Keeping the Hottest Electronics Cool

    The faster and smaller microprocessors become, the more heat they generate. C-Therm’s Trident provides vital insights into the development of all materials that contribute to the overall thermal budget, including thermal interface materials such as thermal grease and gap pads. These materials are typically compressible and the thermal conductivity varies with changes in the densification of the material. Clients use the C-Therm Compression Test Accessory (CTA) to precisely control the compaction of the sample in producing results reflective of the actual application conditions for the material.


    Under Pressure

    C-Therm’s Trident thermal conductivity instrument is helping manufacturers improve the heat transfer properties of liquids. C-Therm’s equipment is unique in offering the capability to accurately measure the thermal conductivity of liquids; the short test time (<1 second) and small sample volume requirements negate the convective errors typical in liquid testing with traditional techniques. As an example, clients in the Oil & Gas field use C-Therm’s High Pressure Cell (HPC) accessory in measuring the impact of elevated atmospheric conditions and temperature on the thermal conductivity of fluids.

    • National Aeronautics and Space Administration (NASA)

      "We purchased the C-Therm MTPS sensor after seeing a demonstration of how fast and easy it is to operate. The instrument provides unequivocal results and provides the flexibility to test powders and liquids. In terms of our satisfaction with the purchase, I'd give it a 10 out of 10 - extremely satisfied."

      Dr. Enrique Jackson

    • Université du Québec à Trois-Rivières

      "We purchased C-Therm's MTPS sensor originally to characterize the thermal conductivity of metal hydrides. We liked that it could operate in a wide range of environments and test different materials. It provides accurate, unambiguous thermal conductivity results. What I've really come to appreciate about it is how easy it is to operate. Our students can train on it for 30 mins and be proficient in being left on their own in running their samples. We have many visiting scholars that used C-Therm for many types of samples. This equipment is really versatile."

      Dr. Jacques Huot

    • Covestro

      "C-Therm has provided our group a fast, accurate capability to test the thermal conductivity of our polymers with C-Therm’s patented high-precision MTPS sensor. The instrument has become very popular within our group for its quick easy reliable measurement and the support from C-Therm has exceeded our expectations. We recently upgraded the unit with the new robust TLS module for work on polymer melts."
