Graphite Loaded Silicon Carbide Seal (GLSC) Description

Graphite Loaded Silicon Carbide Seal (GLSC) actively enhances lubrication through its substantial graphite inclusions, creating a lightweight ceramic product with hardness and strength akin to diamond. Exhibiting high resistance to thermal shock, corrosion, and abrasion, GLSC excels in marginally lubricated conditions and situations involving dry running. Its versatile applications include use in the melting of glass and non-ferrous metals, metal heat treatment, as well as the production of ceramics and electronic components.
