WebThe compression strength of phenolic foam was improved obviously after adding glass fiber. At present, the modification of phenolic resin mainly focuses on flame retardant, heat resistance, and toughening [34], [35], [36], [37]. In this study, lignin was degraded by hydrothermal method. WebThen lignin-based flame retardant was used to replace phenol for modifying phenolic foams (NPLPFX). The limited oxygen index (LOI) and compressive strength of phenolic foam were improved effectively by adding modified lignin when the substitution rate was less than 25%. The LOI and compressive strength of the modified phenolic foam with …
