THB 100 – Rubber Compounds – Thermal conductivity

Elastomer – Thermal Conductivity

Rubbers are renowned for their excellent dynamic properties, boasting qualities like high strength, elasticity, and rebound resilience. By incorporating various polymers into rubber formulations, we can create compounds with enhanced characteristics, such as superior chemical resistance, flame resistance, and resistance to oil.

These rubber compounds find extensive applications across various industries, including automotive, food, chemical, and mechanical engineering. They are used in diverse products like motor bearings, O-rings, tires, shoe soles, cable sleeves, floor coverings, and seals for windows and doors. Many of these applications necessitate a deep understanding of thermal properties, particularly thermal conductivity.

App. Nr. 02-006-005 THB 100 – Rubber Compounds – Thermal conductivity

The accompanying plot illustrates a thermal conductivity measurement of different rubber compounds using the THB-100 (available in new models THB Basic, Advance, Ultimate). In this experiment, a sensor was positioned between two sample components, ensuring a good contact with the sensor. This assembly was then placed in a furnace, and the thermal conductivity measurement was conducted over a temperature range from room temperature to 150°C.

The plot clearly demonstrates variations in thermal conductivity among the different compounds, while some exhibit more similar thermal conductivities. As expected, the thermal conductivity increases for all samples within the measured temperature range, highlighting the importance of understanding these properties in diverse rubber applications.
