The structure and main characteristics of non-metallic expansion joints are explained

The structure of non-metallic expansion joint mainly includes: skin, insulation cotton, stainless steel wire mesh, heat insulation filler layer, baffle plate and frame. 

Skin: It is a kind of high strength sealing composite material, which is compounded by a variety of materials such as silicone rubber with excellent function, with the role of waterproof and air leakage. 

Insulation cotton: itself has the function of sound absorption, isolation flutter transmission, with outstanding elongation and tensile strength. 

Stainless steel wire: an effectiveness of obstructing the loss of debris to the outside, to the lining of non-metallic expansion joints.

Insulation filler layer: the primary ensure of non-metallic expansion joints adiabatic, is composed of a variety of high temperature resistant materials. 

Non-metallic expansion joint baffle: with corrosion resistance, wear resistance has the role of infusion and maintenance of the thermal insulation layer.

Frame: with sufficient strength and rigidity, the material is compatible with the temperature of the medium.
