P-313 Carbonized fiber packing,
              PTFE packing soaked with carbonized fiber
              Flame-resisting carbon fiber packing,
              Polyacryl-nitrile (acrylic fibers) graphite packing


I. Definition:
make the polyacrylonitrile-based fiber into carbonized fiber through high-temperature oxidation, and processed by PTFE with graphite grains on surface.

II. Application:
this product is an ideal substitute for asbestos PTFE packing, it is very suitable for blower, fan and others, and it can be applied in dynamic sealing sections with weak acid or base media or media with a few solid particles.

III. Feature:
1. It has small coefficient of friction (u=0.3), well self lubrication, and it can save energy consumption and reduce the damage to counterpart to prolong its service life.

2. It has well heat conductivity, near the one of metal(10~20kcal), when it is used to the dynamic sealing part with high speed, It can conduct the heat of fabrication out. Therefore, it can avoid the burning of material caused by accumulated heat to prolong its service life, and lower the requirement for cooling of sealing sections.

3. It can be applied to speed sealing. For example: it can get well sealing on high pressure pump with a linear velocity of 25 m/s.

4. It has stable chemical property: as part of the organic components of synthetic fibers have been eliminated during the process, and only carbon is remained, so its chemical property is stable. Meanwhile, in the course of production, there will be a cover of PTFE on the fiber surface, which reinforces its stability of chemical property.
