Description
Phenolic Cotton Rod is made of cotton fabric impregnated with phenolic resin, then heated intoprepreg and rolling into the rod shape, finally put into the different diameters molds, under hightemperature and pressure to cure into the rigid laminated rods. Usually for mechanical andelectrical applications.
