WebPhenolic is a hard dense material made by applying heat and pressure to layers of paper or fabric impregnated with phenolic resin. Phenolic paper is a type of composite used for PCBs (printed circuit boards). It is also known as FR-1 or FR-2. The FR1 has a 130C rating and FR2 has a rating of 105C. Both FR1 and FR2 are used for single layer PCBs.
