We measured the expansion coefficient of Torlon 4203 (polyamide-imide) as a function of temperature between 4.2 and 295 K. The thermal expansion is lower than that of most polymers. The thermal conductivity k between 0.1 and 5 K was also measured: below 1 K, a quadratic dependence on temperature of

โฆ Synopsis
We measured the expansion coecient of glass-ยฎbre reinforced nylon as a function of temperature between 4.2 and 300 K. The linear thermal expansion is about half that of unยฎlled nylon throughout the temperatures investigated. The thermal conductivity in the 0.2ยฑ5 K temperature range is very close to that of unยฎlled nylon and can be represented by the ยฎt curve k 2X42 ร 10 ร5 T 1X77 .
