Phenolic Cotton Cloth Laminate Sheet (3025) |
|
Properties |
Phenolic Cotton
Cloth Laminated Sheets (3025, NEMA C CE L LE and IEC PFCC)
are made of several layers of cotton cloth impregnated
phenolic resin by processing under heat and pressure, which
are widely used in High mechanical properties, machined as
insulating construction parts.
