Carbonized fiber Yarn
Carbonized fiber Yarn Description:
SUNPASS Carbonized Fiber Yarn is a high-performance material specifically designed for the production of braided carbonized fiber packing and other advanced sealing applications. This yarn represents an intermediate phase between PAN (polyacrylonitrile) fiber and fully developed carbon fiber, providing a unique balance of flexibility, thermal stability, and mechanical strength.
The yarn is available in standard form as well as PTFE-impregnated versions, which enhance its sealing capability, chemical resistance, and overall durability under harsh working conditions.
Features & Advantages:
High Thermal Stability: Suitable for elevated-temperature environments where conventional fibers fail.
Excellent Chemical Resistance: Resists most chemicals, solvents, and corrosive media.
Low Friction & Enhanced Sealing: PTFE-impregnated versions offer smoother operation and better sealing performance.
Superior Mechanical Strength: Provides dimensional stability and durability during braiding and long-term service.
Intermediate Carbonization State: Offers flexibility of PAN precursor with improved heat resistance closer to carbon fiber.
Versatile Processing: Ideal for various braiding machines to produce high-quality packing rings and industrial sealing materials.
Available Sizes:
2 g/m
3 g/m
5 g/m
10 g/m
(Custom sizes are also available upon request.)
Applications:
Manufacturing of carbonized fiber braided packing
High-temperature sealing in pumps, valves, mixers, and industrial equipment
