A series of tests has been conducted on thermoset resin systems designed for chimney liners and/or ductwork. To obtain optimum performance and cost efficiency, the material characterization of these systems should include the static and dynamic mechanical properties as affected by temperature. Several resin systems were selected for this investigation based on their resistance to chemical attack in acid environments. For the evaluation of dynamic, or fatigue, properties, five vinyl ester resins and two polyester resins were chosen. Applying the principles of fracture mechanics, the fatigue resistance at room temperature and at 212°F (100°C) was evaluated. A thermal aging study was conducted on two of the vinyl ester resins and the two polyester resins, at temperatures ranging from 320 to 400°F (160 to 204°C). Interpretation of the results from both studies, in combination, provides necessary information for accurate material selection.
