Superior Blocking Agents
Gland Packing 477-1 carbon fiber packing combines new yarn formulation with superior blocking agents. New, low modulus yarn provides the strength associated with continuous carbon filament fibers plus greater flexibility. This makes 477-1 strong, yet pliable, without the brittleness of conventional carbon packing.
Gland Packing 477-1 incorporates a high-purity dispersion of inorganic platelets which prevent penetration of liquids through the packing. These inter-braid construction locks are blocking agents within the packing ring
