Phenolic Cotton Cloth Rod (a laminated material made of phenolic resin-impregnated cotton cloth) is widely used in the following industries due to its high-temperature resistance, wear resistance, insulation properties, and high mechanical strength:

Key Advantages

High-Temperature Resistance: Short-term tolerance up to 200–250°C; long-term use at ~180°C.

Wear Resistance: Ideal for high-friction environments, extending equipment lifespan.

Lightweight: Replaces metal parts to reduce energy consumption.

Insulation: Ensures safety in electrical applications.

Machinery Manufacturing and Equipment Maintenance

Commonly used to produce wear-resistant components such as gears, bearings, and bushings, replacing metal parts to reduce costs, weight, and noise. Its compressive strength and wear resistance also extend equipment lifespan in molds, fixtures, and other high-friction scenarios.

Automotive and Transportation

Primarily used in brake systems (e.g., clutch plates, brake pads) to withstand short-term high temperatures (over 200°C) and friction impacts. Also applied in transmission bushings and driveshaft gaskets, offering lightweight and heat-resistant advantages.

Electrical and Electronics Industry

Serves as insulation supports or blocks in transformers, motors, and high-voltage switchgear, ensuring safe operation under high-voltage conditions. Used as drilling backer boards in circuit board manufacturing to prevent layer separation.

Chemical and Petrochemical Equipment

Employed in pump valve sealing liners, reactor stirrer bushings, and other applications to resist weak acid/alkali corrosion while maintaining structural stability under high temperatures and pressures.

Aerospace and Defense

Modified versions can withstand temperatures above 250°C, making them suitable for engine compartment heat shields and fuel system seals. Their vibration-damping properties are ideal for precision instrument mounts and shock-absorbing pads.

Textile and Printing Machinery

Used in components like yarn guide rollers and printing press drum bearings, leveraging self-lubrication and low-noise characteristics to minimize wear and improve operational efficiency.

Energy and Power Equipment

Applied in hydroturbine bearing bushings and generator insulation supports, demonstrating stable aging resistance in humid, hot, or radiation-prone environments.

Precautions

Avoid prolonged exposure to strong acids, alkalis, or excessive temperatures.

Control machining speeds during processing to prevent material brittleness or cracking.

Phenolic cotton cloth rods remain a critical material in traditional industries due to their cost-effectiveness and balanced performance, particularly in machinery, automotive, and electrical sectors requiring high wear and heat resistance.
