Description
Phenolic Cloth Rod is made of cotton fabric (or linen, canvas) 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.
Canvas Phenolic Rods are made from canvas fabric reinforced with phenolic resin, offering an excellent balance of mechanical strength and electrical insulation. They perform reliably in temperatures from -40°C to 120°C, with low moisture absorption and high dimensional stability. These rods are durable, wear-resistant, and ideal for applications requiring both structural strength and electrical safety.
GOST Standard: 3721, 3722, 3723, 3724, 3725
IEC Standard: PFCC41, PFCC42, PFCC43
NEMA Standard: C, CE, L, LE
3722, 3723, 3724, 3725: Similar to NEMA Grade C, CE, L and LE Respectively, usually for mechanical & electrical applications. 3725 allows fine processing
