The glass fiber powder we produce is made of high-modulus glass fiber filaments. The fiber powder has a high whiteness, with the whiteness reaching 98%. The dispersion of fine fibers in liquids with good fluidity reaches 100%. The diameter of the single fiber filament is 11 um, and the length is 0.15 mm. The lengths of the fiber powder are uniform and consistent. It can be used for a long time in a temperature environment within 500 degrees, with the strength value remaining unchanged and no decline in strength. The glass fiber powder we produce adopts the chopped process, so the fiber lengths are equal and consistent. It is pure fiber and can be quickly dispersed into fine single filaments in liquids with good fluidity such as water and alcohol. Since it is a chopped process, there is absolutely no powder component in the fiber powder, and no other mineral powder or glass powder is added to deceive customers. When customers purchase glass fiber powder, it must be made clear that glass fiber powder is not increasingly fine powder, but maintains fine glass fiber single filaments in the microstructure. Therefore, it can also be called ultra-short glass fiber. The powder only appears as white powder visually. When gently rolled with hands, it must be ultra-fine needle-shaped fibers. It is best to observe under a microscope.
