Product details
If phenolic laminated cloth is to be subdivided, it can also be divided into several types, although they are all very similar. They are all hard plate-shaped insulating materials made of industrial cotton cloth impregnated with phenolic resin paint, dried and hot pressed. Different types are also divided according to the number of cotton cloth yarns.
3025 Cotton sheet is made of cotton cloth (coarse) impregnated with phenolic resin by hot pressing. It has high mechanical properties, especially high bonding strength, and is suitable for use as insulating structural parts in machinery, motors, and electrical equipment, and can be used in transformer oil.
3026 Cotton sheet is made of cotton cloth (fine) impregnated with phenolic resin by hot pressing. The product has high mechanical properties and is suitable for use as rotating vibration-resistant and wear-resistant parts of mechanical equipment.
3027 Cotton sheet is made of cotton cloth (coarse) impregnated with phenolic resin by hot pressing. The product has high mechanical properties and is suitable for use as insulating structural parts in machinery, motors, and electrical equipment, and can be used in transformer oil. The electrical properties are better than 3025 board.
3028 Cotton sheet is made of cotton cloth (fine) impregnated with phenolic resin by hot pressing. The product has the same mechanical properties as 3026, but the electrical properties are better than 3026, and can be used as small parts.
| Product | IEC Standards | Application |
| 3025 | PFCC201 (21 count yarn, coarse cloth) | Mechanical use, low electrical performance |
| 3026 | PFCC203 (30 count yarn, fine cloth) | For mechanical use, low electrical performance, good processing performance |
| 3027 | PFCC202 (21 count yarn, coarse cloth) | For mechanical and electrical use, electrical performance is better than 3025 |
| 3028 | PFCC204 (40 count yarn, fine cloth) | For mechanical and electrical use, the electrical performance is better than 3027 and is suitable for processing small parts. |
Advantages of phenolic resin laminated cloth:
Excellent electrical insulation performance: It has high insulation resistance and withstand voltage, suitable for various electrical equipment.
Good heat resistance: It can work at higher temperatures and is not easy to deform.
High mechanical strength: It has certain strength and rigidity and can withstand certain mechanical loads.
Good wear resistance: It is suitable for some occasions that require wear resistance.
Good processing performance: It is easy to cut, drill, mill and other processing.
Relatively low cost: Compared with other high-performance insulation materials, the cost is low.
We also have different shapes of this products,cotton phenolic bar. There are also similar product 3021 phenolic paper sheet. Welcome to contact us for more details.
cotton phenolic laminate: This board is made of phenolic resin and cotton cloth, has good electrical and mechanical properties, and is often used in mechanical and motor equipment.
phenolic paper laminate sheet: Made of insulating impregnated paper (corrugated paper) and phenolic resin through baking and hot pressing, it is suitable for low-voltage electrical insulation parts, such as knife switch bases and distribution box wiring baffles.
Appearance difference:
Color: Similar
Texture: The cross section of the cloth board clearly shows cotton stripes, while the cardboard does not. On the board surface, the cloth board clearly shows long and fine checkered patterns, while the cardboard surface does not.
