    • A composition is provided that, in one aspect, may be used in the production of sealing materials, such as gaskets. The composition includes a polytetraflouroethylene matrix and a Boron Nitride filler. In one aspect, the Boron Nitride filler may be provided as a hexagonal, close-packed, Boron Nitride filler that is homogeneously dispersed within the polytetraflouroethylene matrix. In at least one embodiment, the composition is formed by combining quantities of polytetraflouroethylene, Boron Nitride filler, hydrocarbon liquid, and solvent. The liquid and solvent may be removed through various processes prior to sintering the composition to form a full-density, Boron Nitride filled, polytetraflouroethylene matrix that exhibits improved sealability, greater resistance to permeation, and less color contamination.
    • 提供了一种组合物,其一方面可用于生产密封材料,例如垫圈。 该组合物包括聚四氟乙烯基质和氮化硼填料。 在一个方面,氮化硼填料可以提供为均匀分散在聚四氟乙烯基质内的六方形,紧密堆积的氮化硼填料。 在至少一个实施方案中,组合物通过组合量的聚四氟乙烯,氮化硼填料,烃液体和溶剂形成。 在烧结组合物之前可以通过各种方法除去液体和溶剂,以形成充满密度的氮化硼填充的聚四氟乙烯基质,其表现出改进的密封性,更好的耐渗透性和较少的颜色污染。
