Heat Distortion Temperature: One of the Top Advantages of CPVC
One of the benefits of CPVC over competitive materials is its superior heat resistance.
Heat Distortion Temperature (HDT) is a very important metric, as it indicates the temperature at which the material will become soft enough to distort even a small mechanical load. If the temperature stays above HDT, permanent deformation will occur. CPVC generally is used in hot temperature environments since it has one of the highest HDTs among competitive plastics. The table below shows the heat distortion temperature (HDT) as compared to other plastics. While the exact values will differ due to grade and manufacturer, the general trend will remain true: CPVC compound has one of the highest HDTs in the plastics industry.
