Phenolic Cotton Cloth Laminated Rod 3725/PFCC41
Phenolic cotton cloth laminating stick is made of cotton cloth impregnated with phenolic resin and hot-pressed by a forming die. It has a round cross-section rod and has high mechanical properties. It is suitable for insulating structural parts in electrical equipment and can be used in transformers. Used in oil.
3725 is mainly used as insulating machine parts of electric equipment, screw and wear resistant component of machinery, etc.
Stratification and dregs are not allowed after machining.
