Characteristics of Vinyl Ester Laminates Suitable for Chimney Liner Applications after High Temperature Thermal Stress

摘要

Chimney liner fiberglass laminates made from vinyl ester resins need to survive brief high temperature excursions during non-typical plant operations. A test vehicle was developed to characterize laminate performance based on differences in appearance, mechanical, and thermal properties before and after a thermal excursion. High performance vinyl ester resins perform exceptionally well in these tests as they exhibit high levels of property retention.
