The offered Non-metallic Expansion joint moves in different directions simultaneously; having almost no reactive forces and require little installation space. Its adaptation to existing physical conditions is quick. This can be transported and installed easily. With good dielectric strength and low coefficient of thermal expansion, this joint provides low thermal conductivity and resistance against corrosion. This Non-metallic Expansion joint enables to collect molten metal slag. It is a great substitute of asbestos based textiles. In addition, this is safe against mildew, heat, rot and acids.
