PU-Aerogel as reference material with low thermal conductivity values for thermal conductivity measurements

Description of material
Mechanically stable aerogel board based on polyurethane, which has a low thermal conductivity < 0.025 W/(mK). A more detailed sample description is available in the following publication. 

What will be delivered
Upon request, interested parties will receive specimens with a specific thermal conductivity value valid for these specimens with an expanded standard uncertainty for the determined thermal conductivity value. In addition, a correction formula is provided to account for ambient atmospheric pressure and temperature to allow the most accurate comparison with the supplied reference value.

The following specimen sizes can be provided:
- Appr. 350 mm x 350 mm with a board thickness of 14 mm
- Smaller specimens on request. The material is mechanically machinable.
- The reference value of the thermal conductivity of the sample is measured for one temperature point between 20 °C and 40 °C.


The reference samples are invoiced at nominal cost on a quotation basis. The costs include material, measurement and shipping costs.

Interested parties are welcome to contact us directly and specify their requirements, such as specimen size and measurement temperature.
