Braided packing made of type E textured glass. Its nominal diameter of fibres is 6 to 11 micrometres. Thanks to suitable weave and texture the packing is elastic and has significant volume of air trapped between fibres. That phenomenon ensures excellent thermal insulation.
Used for sealing chambers, driers and furnaces at high temperatures. High chemical resistance of glass fibres allows to use this packing in chemical equipment, and exhaust systems for hot flue and post-reaction gases. This packing is resistant to majority of aggressive chemicals, except for fluoride, strong alkalis, and phosphoric and sulphuric acid. Also used as thermal insulation of hot components.
