摘要：

A dilatometer measuring thermal expansion coefficient at low temperatures is introduced. The thermal expansion coefficient of phenolic foam, a widely used thermal insulation material, was measured in the temperature range of 77-293 K by the dilatometer. The results showed that the thermal expansion coefficient of phenolic foam was very low in the tested temperature range with an error of about +/-7.3%. (C) 2003 Elsevier Ltd. All rights reserved.
