What is XX PAPER PHENOLIC?
XX Paper Phenolic is a paper-based high pressure laminate suited for general purpose electrical applications. The material has good mechanical properties and excellent moisture resistance. XX machines well and may be punched cold up to .046″ and hot punched up to .093″.
XXP Paper Phenolic is better than XX grade in both electrical and moisture-resisting properties. XXP is more suited for hot punching and falls between XP and XX in punching and cold-flow characteristics.
