Phenolic paper laminated sheet is made of cellulose fiber paper impregnated with phenolic resin by processing under heat and pressure. Phenolic paper sheet can be processed into all kinds of insulation parts. The products are widely used for transformers, electric motors, cabinets, control boxes, electric switches, household appliances, railway, automobile, computer, medical appliance and etc.
PFCP308 sheet: Good electrical performance under high humidity condition, suitable for hot punching. Similar to PFCP206 sheet but with flame retardant property.
