Phenolic Novolac And Resol Resins - Phenolic thermosetting resin …

Phenolic resin chars when heated to temperatures greater than 480°F (250°C). This process continues at very high temperatures greater than 1,000°F (>500°C), until the resin completely converts to amorphous carbon. This characteristic contributes to the unique ablative properties of phenolic resins.
