- Abstract
- Plastic materials are being chosen more frequently for various applications in solar energy systems. Problems with materials in solar systems have indicated a need for standards to assess the performance and durability of the materials. In this investigation laboratory studies have been performed to obtain data needed to develop standards to screen plastic containment materials for the effects of heat and for compatibility with heat transfer fluids. Five absorbers, three plastic pipe materials, and three plastics used in storage applications were included. They were evaluated to assess their durability after exposure to heat aging at 100C and 125C and to chemical compatibility with six heat transfer fluids at room temperature and at 70C. The results of the laboratory tests are presented and a draft standard to screen plastic containment materials is proposed.
