Phenolic Cotton Cloth Sheet is made of cotton cloth impregnated with phenolic resin by hot pressing. It has strong mechanical properties, oil resistance and dielectric properties.
It is suitable for machinery, motors, electrical equipment for insulation structure parts, and it can be used in transformer oil. Among them, PFCC203 high-strength phenolic cotton cloth laminate is suitable for mechanical equipment for running, anti-vibration parts.
1. High electrical and mechanical performance.
2. Easy for fabricaion, good dimentional stability, physical strength, resiliency.
3. Better machinability than other product.
| IEC | Characteristics |
| PFCC201 | Coarse cotton cloth, general mechanical and electrical properties |
