SELECTED PROPERTIES OF COMMERCIAL HIGH-DENSITY HARDBOARDS

Information on the basic properties of hardboards is necessary for pro per development of new end-use products. In this study, selected prope rties of 10 high-density hardboards from 6 manufacturing mills were de termined. Results were compared with property requirements of the Amer ican National Standards Institute (ANSI) and with property values from a hardboard study in the 1960s. With few exceptions, property values exceeded the ANSI requirements and were within the range of those in t he 1960s study.
