Description
Phenolic paper laminated sheet is a layered material obtained by hot pressing two or more layers of electrical insulating paper impregnated with synthetic thermosetting resins. Because the composition of the phenolic paper sheet includes electrical insulating paper, the laminated sheets have a high crushing strength and increased flexibility. Phenolic paper sheets are easy to machine by drilling, cutting and forging. Phenolic paper laminated sheet has good mechanical properties for normal electrical load. Phenolic paper plates have good heat resistance but are inferior in terms of parameters compared to phenolic cotton laminated sheets and epoxy fiberglass laminated sheets.
