Made of cotton fabric impregnated with phenolic resin, then heated into prepreg and rolling into the rod shape, finally put into the different diameters molds, under high temperature and pressure to cure into the rigid laminated rods. Usually for mechanical and electrical applications.
3721, 3721-1：For mechanical & electrical applications. 3721 is better than 3721-1 in strength， 3721-1 is economical type of product 3721
3722, 3723, 3724, 3725： Similar to NEMA Grade C, CE, L and LE Respectively, usually for mechanical & electrical applications. 3725 allows fine processing
PFCC41, PFCC42 and PFCC43:IEC Grade, PFCC41(fine cloth), PFCC42(coarse cloth) and PFCC43 ( extra coarse cloth)
