High Silica Cord for Seal is braided by high silica yarn with 96% SiO₂ into round, square or ring shape, filling with silica thread, rope, mat or fabric. It also called Silica Packing Rope. Silica cord for seal can be used for a long time without changing its properties at the temperature 900℃. Its softening point is closely 1700℃ and it can be used under 1000℃ situation for a long time.

Silica cords for seal are silica ropes used primarily as sealing packing for high temperature sealing applications. Silica cords for seal withstand extreme temperatures up to 1,800°F (1,000°C) and are used as tape cores, furnace door gaskets, high temperature caulking, and coke oven door seals. Silica ropes are used extensively by the Power Generation, Oven, Furnace, Refinery, Construction, Shipbuilding, Welding and Metal Processing Industries.
