STYLE 2070
Expanded PTFE
Graphite Yarn with a Kevlar Core
CONSTRUCTION
Style 2070 packing is an interlock braid, utilizing TEADIT s patented EGK yarn and a high temperature break-in lubricant EGK yarn totally encapsulates a high strength Kevlar core in an expanded PTFE/graphite jacket. The Kevlar core contributes exceptional mechanical strength and dimensional stability, while the PTFE/graphite jacket provides chemical resistance, heat conductivity, self lubrication and a low coefficient of friction.
APPLICATION / SERVICE
Style 2070 is a superior general service and corrosive service packing. Its high resistance to extrusion (four times higher than conventional PTFE/graphite packings) makes Style 2070 ideal for handling chemically aggressive fluids in high surface speed and high pressure applications.
