Quartz fiber sewing thread is known for its exceptional high-temperature resistance, enduring up to 1050° C without significant degradation, surpassing other high-temp threads like aramid, fiberglass, or ceramic. It's ideal for aerospace, automotive, and industrial applications requiring extreme heat resistance, such as insulation blankets and protective clothing. Additionally, quartz thread maintains tensile strength at high temperatures and offers excellent electrical insulation properties.
FEATURE
Outstanding Heat Resistance:
Operable at 1050 - 1200°C long - term, with a softening point near 1700°C, maintaining stability in high - heat settings. Ideal for aerospace high - temp components.
Superb Fire – Retardancy:
Meets DIN4102 A1 standard, non - flammable, ensuring safety. Used in fire - proof products like clothing and curtains.
Low Thermal Conductivity:
Just 1.4W/M•K, minimizing heat transfer, suitable for insulating items like filter bags.
High Chemical Stability:
Resistant to acids, alkalis, temperature variations, and stretching, suitable for corrosion - resistant fabrics.
High Strength:
Tensile strength up to 3790Mpa + (e.g., 6000Mpa for Shenjiu brand), 3 - 4x that of glass fiber. Enables high - speed sewing.
APPLICATION
Fire – protection:
For making fire - proof gear like clothing, curtains, gloves, and blankets.
Industrial High - temp Equipment:
Sewing and tying in 1200°C - rated industrial heaters, and aerospace high - temp parts.
Insulation:
Used in sewing high - temp filter bags, insulation blankets, and covers.
Insulation (Electrical):
As insulating reinforcement for high - temp wires, and in electrical insulation and cable filling.
Others:
Winding heating elements, as a sealing material, and in rubber hoses and high - temp tapes.
