Manufacturing Process

Slade manufactures all of its own patented graphite yarns. The advantage is that each individual strand has its own unique core made of high tensile carbon fiber. Our yarns are protected by US & EU patents, and were developed to conduct heat like steel alloys, to transfer the heat away from the shaft.

When Slade Foil is compressed by 25% (the denser the better), die-formed density is achieved in the stuffing box. This forms a “heat sink” in the stuffing box, eliminating the need for flush-water to cool the shaft sleeve in most applications. In addition, Slade reduces the number of oxidation sites in the packing yarns so that Packing can be used in more severe temperature and chemical applications than competitor’s packings.
