- Abstract
- Cured specimens of urea-formaldehyde foam from four major manufacturers were exposed to several high-humidity conditions at moderately elevated temperatures in a temperature and humidity chamber. These conditions included 40 deg C (104 deg F) at 92% rh and 50 deg (122 deg F) at 92% rh. The occurrence of moisture absorption, shrinkage, weight loss, and crumbling of the speciments during the exposure periods was examined.
