377 CarbMax™ Packing

Perth - November 18, 2022

Superior Carbon Fiber

Chesterton 377 CarbMaxc packing combines one of the highest carbon content fiber yarns using the latest formulations with the newest blocking agents. This yarn provides the enhanced strength and toughness of a continuous multi-filament carbon fiber with increased durability. This makes the 377 firms yet resilient, with high thermal conductivity over conventional carbon packing.
Chesterton 377 incorporates a specially formulated inorganic dispersion applied throughout the packing braid, preventing penetration and migration of gases or liquids. The inter-braid construction provides superior interlocking between all the strands of yarn, adding additional blocking agents to this unique mechanical packing composition.
