The drawings show a sliding seal composition used for molding a seal member. In FIG. 1, the sliding seal composition 1 is made of polytetrafluoroethylene (PTFE).
The raw material powder is calcined to obtain a powder (particle size, about 50 μm
Polytetrafluoroethylene recycled to about 60μm)
Recycled powder and polyphenylene sulfide (PPS) are appropriately mixed as a base resin, and one of carbon fiber (CF), glass fiber (GF), and aramid fiber (AF) is used as a filler for filling the base resin. Only in a suitable amount as short fibers, and only one of graphite powder (Gr) and molybdenum disulfide (MoS2) in a proper amount as a solid lubricant, and then a commonly known hot coining molding method ( (Compression molding method).

The blending amount of wt% to 80 wt% is optimal, and when the blending amount is reduced to 20 wt% or less, the elongation (elasticity) becomes extremely small and the molding material becomes brittle. If the amount is more than 80% by weight, the wear resistance becomes very poor, and the durability required for long-term use cannot be obtained.

The optimal blending amount is up to 70 wt%. When the blending amount decreases below 10 wt%, the mechanical strength decreases. When the blending amount increases above 70 wt%, the elongation (elasticity) decreases and the molding material becomes brittle. . In addition, since the blending amount of polytetrafluoroethylene is reduced, the friction coefficient is increased, and the slidability is reduced.

If the amount is less than wt%, the creep resistance and the abrasion resistance decrease, and the durability required for long-term use cannot be obtained.
When the compounding amount is increased to 10 wt% or more, the partner material is easily damaged, and the dispersibility of the molding material is reduced.
Deformation or distortion occurs.
