This product is produced by extrusion of high molecular weight EVA/HDPE (ethylene copolymer/high-density polyethylene) as raw materials. It is suitable for various types of engineering waterproofing, anti-seepage, moisture-proofing, air isolation, anti-pollution, drainage, etc.

The raw materials generally include: ethylene/vinyl acetate copolymer (EVA), high-density polyethylene (HDPE), and ethylene copolymer modified asphalt (ECB) resin.

Product Features
  1. High tensile strength, above 16Mpa at room temperature; large elongation at break , up to 550% or more at room temperature; good stress resistance and crack resistance, and easy to adapt to water expansion and rupture of structures;
  2. Good low temperature resistance and bending performance ( still has good bending performance below -35℃ ), and can adapt well to changes in ambient temperature;
  3. It has excellent flexibility, wear resistance, puncture resistance, dimensional stability, good adhesion and is easy to construct;
  4. It is resistant to corrosion by acids, alkalis, salts and other media, and mold, and has no chemical pollution . It has stable performance against acids, alkalis and other chemicals in concrete or sand, and is suitable for underground projects such as tunnels and civil engineering.
  5. The overlapping seams of the roll materials can be hot-melt welded to achieve ideal construction effects.
Scope of application
  1. Waterproofing projects for railways, subway tunnels , highways, and railway culverts ;
  2. Waterproofing, anti-seepage and moisture-proofing projects for underground buildings such as municipal engineering, sewage treatment pools and civil air defense projects;
  3. Anti-seepage projects such as water conservancy projects, dams, drainage ditches and artificial lakes.
Precautions
  1. When laying plastic waterproof sheets, they should not be stretched too tight, and sufficient space should be left according to the flatness of the base surface;
  2. The surface of the welding material must be wiped clean and free of water, oil and dirt;
  3. Strictly check the welding quality and make sure there is no leaking or skipping of welds .
