The two packings HV 1055 and HV 1057 certainly are one of the most important results of our technical engineered research. Using a special yarn manufactured starting from a PTFE/graphite leaf folded around continuous kevlar® fibers (#1055 or synthetic fibers (#1057), then braided with HCD® system, the new packings achieved can now be applied on toughest working conditions thanks to the high tensile strenght of the aramidic fibers and the heat dissipation capacity of the carbon yarn surrounded by the PTFE/graphite. High pressure, bad mechanical conditions of the equipement, strong chemicals, high peripheral speed are just a few of the conditions where the new packing can be succesfully used.
