Made of alkali-free glass fiber cloth, combined with epoxy resin, hot-rolled, stretched, baked and cured, it has high mechanical properties and stable electrical properties under high humidity, suitable for use as Insulating structural parts for mechanical, electrical and electronic equipment.

The main advantages of this insulating tube are:

1. Light weight, high strength

The density of Fr4 insulating tube is between 1.8-2.0, and the density is only 1/4-1/5 of that of carbon steel, but its tensile strength is greater than that of carbon steel, and its strength can even be compared with that of high-grade alloy steel. Therefore, it has good results in the application of aviation, rockets, aircraft, high-pressure vessels and other products that need to reduce automation.

2. Low loss, long life, good electric insulation

FRP is a non-conductor, and the electrical insulation of the pipeline is excellent, which is most suitable for power transmission, densely populated areas of telecommunication lines and minefields. The heat transfer coefficient of FRP is very small, only 0.23, which is five thousandths of that of steel, so its thermal insulation performance is also very good.

3. Cold and heat resistance, small frictional resistance

The glass fiber pipe can be used for a long time in the temperature range of -40°C -70°C, and the high temperature resistant pipe resin with a special formula can also work normally at a temperature above 200°C. Small frictional resistance and high conveying capacity. The inner wall of the glass steel pipe is very smooth and has very little friction.

4. Anti-aging, high corrosion resistance

Since the main raw material of FRP is composed of polymer unsaturated polyester resin and glass fiber, it can resist the corrosion of acid, alkali, salt and other media and the corrosion of untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. Erosion, in general, can keep pipelines running for long periods of time.

5. Various shapes and rich colors

FRP can be customized into various shapes for different purposes, and the colors are also colorful.
