- Abstract
- The rapid growth of the use of thermoplastic pipe for plumbing in housing has prompted a study to determine the critical factors affecting the performance of the pipe materials. The emphasis in this preliminary study is on thermal properties such as the softening point, relaxation of thermal stress, glass transition temperature, hardness-temperature relationships, and decomposition temperature. The techniques used were thermal mechanical analysis (TMA), thermogravimetric analysis (TGA), and hardness. Preliminary results obtained on several pipe samples of PVC and CPVC commercial samples are reported.
