High Temperature Heat Resistant PTFE Coating Fiberglass Ceramic Fabric Expansion Joints
Product Overview
The high temperature heat resistant PTFE coating fiberglass ceramic fabric expansion joints are designed for thermal movement compensation vibration absorption and gas sealing in high temperature ducting and industrial pipeline systems.
These expansion joints are manufactured from woven fiberglass fabric or ceramic fiber fabric coated with PTFE. The PTFE coating provides excellent chemical resistance non stick surface properties and long term durability under aggressive operating environments. The fiberglass or ceramic base fabric ensures superior heat resistance and structural strength.
They are widely used in power plants industrial furnaces exhaust systems and ventilation ducting.
