Minseal 1200 PTFE Graphite Packing is braided with graphitized PTFE (Teflon) yarn manufactured through a specially engineered process. High purity micronized graphite is encapsulated in a PTFE matrix structure. The graphitized PTFE yarn combines high thermal conductivity from graphite with all other properties of PTFE. This combination gives 1200 PTFE Graphite Packing great sealing properties that other products cannot offer: compressible, durable, self-lubricating, chemical resistant and heat dissipating. Applications include various pump gland packing, valve stem packing and other mechanical seals for many tough sealing environments in industries of petroleum, chemistry, power plant, paper mill, printing and others.
