Product details

FR4 laminates is a fire rated electrical-grade, dielectric fiberglass laminate epoxy resin system combined with a glass fabric substrate.The abbreviation "FR4" means: F (for flame) and R (for retardant), # 4 epoxy.FR4 grades offer excellent chemical resistance, flame ratings (UL94-VO) and electrical properties under dry and humid conditions. FR4 also features high flexural, impact, superior mechanical strength and bond strength at temperatures up to 130°C. FR4 is suitable for structural, pc boards and electrical applications.

G10 material is a composite material made of glass cloth and epoxy resin. It was developed as an aircraft material when it was invented, it can withstand great strength. G-10 is not permeable with water and liquid, and it has the characteristics of insulation, anti-acid and alkali, and the weight is light.

A continuous woven glass fabric laminated with an epoxy resin. This grade is extremely high in mechanical strength, has low water absorption and dissipation factors and has superior electrical characteristics, which are exhibited over a wide range of temperatures and humidity.

Technical specifications:

(1)Adopting special epoxy phenolic layer glass cloth board for electrician, made by physical processing. With high mechanical and dielectric properties, heat-resistant, suitable for motors, inductors, ballasts and other slot spacing equivalent insulation.

(2) The appearance of the surface should be flat, the processing surface should be straight, no cracks and burn marks, no internal delamination cracks.

The field of application:

1. It is suitable for use as insulating structural parts in electric motors and electrical equipment, and can be used in humid temperature environment and transformer oil. Good heat resistance and moisture resistance, and good machinability, heat-resistant grade B.

2. Epoxy gasket with high mechanical properties and electrical properties, widely used in generators, motors, electronic appliances as insulating materials and components. In the transformer oil pressure environment and humidity environment is also very suitable.

3. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during the curing process.

The principle characteristics:

1. The vast majority of insulating materials are resistant to high temperatures only up to 135 ° C indirect use temperature, and can not be directly in contact with the flame, while the epoxy board after contact with the flame does not burn, does not blister, does not fracture.

2. The most important component of epoxy board is epoxy resin, itself with acid and alkali resistance and other chemical corrosion performance, through the SEFA Association testing laboratory countertops up to 49 kinds of chemical reagents test.

3. Epoxy board does not contain any paper components, can effectively resist moisture in the air, especially for operating table splash area, never need to worry about moisture expansion and deformation.
