ISOTEK ROUND BRAID


GENERAL INFORMATION
ISOTEK Round braid is dense, resilient, high performance ceramic fiber material fabricated from ceramic fiber yarn braided around a core of ceramic fiber rope to form a packing in round section. It is widely used for a broad variety of high temperature gasketing, packing and sealing application.

 

ISOTEK Round braid contains approximately 18% organic fiber which burns out at high temperatures, causing some smoking and outgassing, but has no effect on the properties of the products.
