PVC plastic water stop material made of polyvinyl chloride resin and various additives through mixing, granulation, extrusion and other processes. The product uses the elastic deformation characteristics of the elastomer material to play a role in leak-proof and anti-seepage in the joint of the building structure. The PVC plastic waterstop has the characteristics of corrosion resistance and good durability. The plastic waterstop is mainly used for the foundation works that are integrated in the construction joints and deformation joints when concrete is poured. Such as tunnels, culverts, diversion aqueducts, dams, liquid storage structures, underground facilities, etc.
PVC plastic waterstops are generally produced according to drawings, and molds can only be carved after drawings are made. This is a customized product, and the dimensions are customized according to customer requirements. This is the same as ordinary rubber waterstops. When qualified products are shipped from the factory, the hardness, tensile strength, elongation at break, tear strength, brittleness temperature, and hot air aging must all comply with relevant industry standards.
In terms of product color, the color of PVC plastic waterstop can be processed into a variety of colors, such as blue, black, yellow, and gray. There is a lot of choice, and the natural rubber waterstop is black.
Specifications:
width is from 150-500mm, and thickness can be 6-10mm.
