Epoxy glass fiber cloth laminate, commonly known as epoxy glass fiber board, has revolutionized industrial insulation. With its exceptional electrical insulation, high mechanical strength, and resistance to extreme temperatures, it has become an indispensable material in modern manufacturing.
1. Electronics and Electrical Engineering
This sector is the core market for epoxy glass fiber boards, accounting for over 60% of total usage.
- PCB Substrates: The FR-4 model serves as the primary substrate for Printed Circuit Boards.
- High-Density Layouts: Its low dielectric loss prevents short circuits, making it ideal for mobile phones, computers, and routers.
- Safety Components: It is widely used for insulating gaskets, terminals, and partitions to ensure electrical safety during equipment vibration.
2. Electric Motors and Appliances
Its mechanical durability makes it a preferred choice for motor insulation.
- Reliability: Used in motor stator/rotor pads and transformer partitions to reduce leakage risks.
- Thermal Endurance: It withstands high-temperature environments, significantly extending the service life of household and industrial motors.
3. Aerospace and New Energy
In high-end manufacturing, specialized laminates like the G11 model are essential.
- Aerospace: G11 is utilized for aircraft instrument brackets due to its lightweight and extreme temperature resistance.
- Renewable Energy: It adapts to high-voltage and high-humidity environments in photovoltaic inverters and charging piles.
4. Mechanical Processing and Transit
Beyond insulation, these boards excel in mechanical structural parts and rail transit components.
- Customization: Its excellent processing performance allows for precise cutting, drilling, and polishing.
- Durability: Moisture-proof and anti-corrosion characteristics ensure stability in complex industrial environments.
