SCOPE The material described by this specification is a flexible, heat treated braided type “E“ glass fiber sleeving, reinforced with stainless
3、 steel wire, and incorporating two or more significantly heavier ends which spiral around the circumference, providing a standoff air gap for superior thermal insulating characteristics. A cross-linked polymeric coating is added to prevent fraying. 2. APPLICATION This specification was released orig
