Braided packing technology
Valve stems, drive shafts and other shafts are often sealed with braided packings made from carbon and graphite yarns. Braided packings provide an effective seal against liquids and gases and are used in many application sectors, such as the petrochemical and chemical industries, paper manufacture, steel mills and conventional and nuclear power stations.
Yarns from SGL Group ensure that the packings have a long service life. They are resistant to most chemicals, thermally stable and have high thermal conductivity, so that they can also be used at high temperatures. We can control the properties of the yarns through suitable choice of starting materials and processing temperature. Our carbon yarns have a carbon content of 95% - 99%. Our graphite yarns even have a carbon content of 99% and higher to ensure excellent chemical and oxidation resistance. They are abrasion-resistant and self-lubricating and exhibit outstanding resilience.
