3mm chopped glass fiber

Short-cut glass fiber, also known as glass fiber short-cut yarn, is produced by melting quartz sand at high temperatures and drawing the yarn with a special sizing agent (softener). The yarn is then cut short through wet-cutting in-line or by cutting the product itself. It is primarily used to reinforce thermoplastic plastics. Due to its favorable cost-performance ratio, it is particularly suitable for use as reinforcing material in the shells of cars, trains, and ships in combination with resins. It is also used in high-temperature needled felt, car sound-absorbing panels, hot-rolled steel, and more. Its products are widely used in automotive, construction, aviation, and daily用品 sectors, including automotive accessories, electronic appliances, and mechanical products. It can also be used to enhance the impermeability and crack resistance of mortar concrete, serving as a competitive alternative to polyester fiber, lignin fiber, and others for reinforcing mortar concrete. It can also improve the high-temperature stability, low-temperature crack resistance, fatigue resistance, and extend the service life of asphalt concrete surfaces.
