Advantages: 1. High temperature resistance; Quartz fiber sewing thread is made of quartz fiber. The long-term use temperature is about 1050℃, and the softening point temperature is about 1700℃. 2. Fire and flame retardant; In case of fire does not burn, high safety performance. 3. Low thermal conductivity: The thermal conductivity of quartz fiber is only 1.4W/M∙K, which improves the thermal insulation of the whole product. 4. Stable chemical performance; Can be used in a variety of environmental states (acid, alkaline, cold, high temperature, drawing, etc.), stable performance, long service life. 5. High intensity; It can be used directly on high speed sewing machines. Usage: 1. It can be used for sewing fireproof fabric such as fireproof clothing, fireproof curtain, fireproof quilt, fireproof high-temperature gloves, fireproof felt, fireproof welding gloves, etc. 2. High temperature industrial furnaces, heaters, hair dryers, electric ovens and other heating wire components that can withstand temperatures of 1200 ° C, and high temperature parts of aerospace technology, such as stitching, binding wires and ropes, etc. 3. Used for sewing high temperature resistant, heat insulation and heat preservation materials such as high-temperature filter bag, heat insulation blanket, heat preservation protective cover, etc. 4. Electrical insulation materials, cable packing. 5, winding electric heating wire and heating element, thermal insulation material.
