Product introduction
EVA waterproof membrane
Introduction
EVA waterproof membrane is a kind of anti-seepage material made of high molecular polymer as the basic material, the production process adopts two-stage co- extrusion single stack rod extrusion method. The raw material resin EVA is added with reinforcing agent and antioxidant. After heating, melting, plasticizing, extrusion forming and traction, the sheet formed can also be combined with geotextile (signal layer) to form a composite waterproof board. Extrusion and calendaring method can also be used to melt and plasticize the resin extruder The molten sheet blank extruded from the slit die of the machine head is integrated with the sling, and then rolled and cooled into a smooth film by roller calendering, or integrated with the geotextile with sling, and then rolled and cooled into composite waterproof plate.
