3025 Phenolic cotton cloth sheet and rod are made up of cotton saturated with phenolic resin, and are laminated under pressure and heat. This kind o thermoset composite material has been proved to be perfect for parts requiring outstanding mechanical strength and electrical properties for machinery, electric motor and electrical appliance.

♦ 3025-210, the basic cloth of this grade was in 10 yarns, and dielectric breakdown strength is less than 10KV, suitable for medium and low voltage electrical panel which require lower insulation properties.

♦ 3025-221 the basic cloth of this grade was in 21 yarns, and dielectric breakdown strength is less than 25KV, Compared to 210, 221 own the high mechanical strength, stable and precision machining size, good electrical insulation properties, suitable for high voltage electrical grid, precision gears, sliding rails which require high insulation properties.
