Phenolic paper-based insulating board (Bakelite board)
Phenolic paperboard—commonly known as Bakelite board—is classified under the national standard grade 3021 (phenolic laminated paperboard). It is a laminated thermoset material produced by impregnating bleached wood pulp paper with phenolic resin and curing it under high temperature and pressure. It is primarily used for electrical insulation, heat-resistant applications, and CNC fixture machining, representing a completely different material system from PU modeling board.
