Chopped glass fiber is also called glass fiber chopped strand. The raw silk drawn with a special sizing agent is chopped online by wet method.

Mainly used to reinforce thermoplastics. Because of its good cost performance, it is particularly suitable for composite with resin as a reinforcement material for the shells of automobiles, trains and ships: used for high temperature resistant needle felt, automobile sound-absorbing sheets, hot-rolled steel, etc. Its products are widely used in the fields of automobiles, construction, and aviation daily necessities. Typical products include auto parts, electronic and electrical products, and mechanical products.

It can also be used to enhance the anti-seepage and anti-cracking inorganic fiber of mortar concrete. It is also a substitute for polyester fiber, lignin fiber and other products used to enhance the competitiveness of mortar concrete. It can also improve the high temperature stability and low temperature crack resistance of asphalt concrete. And fatigue resistance and prolong the service life of the road surface.

Glass fiber chopped yarn stitch knitted fabric is also called knitted felt or woven felt, which is different from ordinary fabrics and felts in the usual sense. A typical stitch knitted fabric is a layer of warp yarn and a layer of weft yarn overlapped together, the warp yarn and weft yarn are knitted together to form a fabric through stitching.

Unidirectional glass fiber chopped strand fabric is a four-warp broken satin or long-axis satin fabric woven from thick warp yarns and fine weft yarns. It is characterized by high strength in the main direction of the warp.

Glass fiber chopped yarn is usually used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy. Because it is widely used in many fields, people pay more and more attention to the supply of high-grade glass fiber yarn.
