Polyethylene closed-cell foam plate is also called joint filler board, which is a new type of joint water-stop material . It has been repeated proved that the performance is much better than wood, cork, rubber, asphalt by China's Ministry of Communications Academy of Sciences .



  1. Low surface bibulous rate, good performance of anti osmosis
  2. Resistance to solvent corrosion like acid, alkali, salt, oil, etc.
  3. Good performance of ageing resistance
  4. Not flow in high temperature, not embrittle in low temperature
  5. Closed sell prevents water absorption
  6. Easily worked can be cut with knife
  7. Structural expansion in concrete brick
  8. High density withstand hydrostratic pressure
  9. Excellent and quick recovery after compression
