Basalt Fiber Sewing Thread

Home Product Center Fibers Category Basalt Fiber Sewing Thread

Basalt fiber sewing thread is made from twisted basalt fiber yarn as the base material, with a coating of polytetrafluoroethylene (PTFE) on the surface. It features high strength, excellent abrasion resistance, flame retardancy, and environmental friendliness. This sewing thread is widely used in the stitching of high-temperature resistant fabrics, making it ideal for applications in extreme environments requiring high performance.
