Let`s briefly talk about how to identify the quality of Glass Mat?

Glass Mat is an inorganic non-metallic material with excellent performance. There are many types. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. However, the disadvantages are brittleness and poor wear resistance. Glass Mat is often used as reinforcing materials in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other fields of the national economy.

Glass Mat is an inorganic non-metallic material with excellent performance. There are many types. The advantages of Glass Mat are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. However, its disadvantages are brittleness and wear resistance. Poorly, the Fiber Glass yarn is made of glass balls or waste glass as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its single filaments ranges from a few microns to more than 20 microns, which is quite At 1/20-1/5 of a hair, each fiber strand is composed of hundreds or even thousands of single filaments.
Glass Mat is made of glass as raw material and processed by various forming methods in the molten state. Generally divided into continuous Glass Mat and discontinuous Glass Mat. The most popular ones on the market are continuous Glass Mat. There are two main types of continuous Fiber Glass produced according to my country's current standards.
One is medium Glass Mat, code-named C; the other is Fiber Glass, code-named E. The main difference between them is the content of alkali metal oxides. There is also a Glass Mat on the market that is a non-standard product. Generally commonly known as high Glass Mat. Its alkali metal oxide content is above 14. The raw materials for production are broken flat glass or glass bottles. This kind of Fiber Glass has poor water resistance, low mechanical strength and low electrical insulation, so it is not allowed to be produced.
