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. The graphite yarns are protected by US & EU patents. They were developed to conduct heat like steel alloys, to transfer the heat away from the pump shaft and valve stem.

Graphite is resistant in high temperatures to 850° F (450°C) in hot air, 1300°F (700°C) in steam environment. In reducing environments which are almost totally oxygen exclusive, such as nitrogen or carbon dioxide, the threshold is about 1650°F (900°C). In the absence
