Product  Features
 1) High tensile strength, over 16 Mpa at normal temperature;  high elongation at break, over 550%; good resistance to stress cracking caused by  water swelling and rupture in structure.

  1. Excellent resistance to low temperature bending and environment temperature changes.

3) Soft texture, well adapt to  substrate, convenient construction.
 4) Resistance to mildew and acid & alkali corrosion,  especially suitable for railway highway tunnels, civil air defense, culverts and other underground engineering.
 5) Excellent hot gas welding property, seamless and tight once welded.

  1. Product contains no volatile solvent or toxic gases, eco-friendly.
