ISOTEK TWSITED ROPE


GENERAL INFORMATION
ISOTEK Twisted rope is fabricated from ceramic fiber yarn twisted left hand/right hand together to form a rope of specified diameters ranging from 3 mm to 50 mm, with glass filament, stainless steel wire or high temperature alloy wire inserted to provide high strength at elevated temperatures.

ISOTEK Twisted rope contains approximately 18% organic fiber which burns out at high temperatures, causing some smoking and outgassing, but the rope retains enough strength to be used at high temperatures. ISOTEK Twisted rope is also available overbraided with wire as gasket and seals for furnace door.
