1. Equipment Overview
The HDPE/PP waterstop sheet production line is a specialized extrusion system for manufacturing high-polymer waterproof strips, widely used in construction joints, tunnels, dams, and other waterproofing applications. Utilizing high-temperature melt extrusion + precision mold forming, it produces waterstops with high elasticity, corrosion resistance, and long service life.
Plastic T-Grip sheet is made of HDPE and PP, produced by extrusion process. T-grip sheet is mainly used in basis construction concrete casting of the construction joints and deformation constitute the basis of engineering for the integration and joints of concrete, such as tunnel, culvert, aqueduct, dam, reservoir structures, underground facilities; Because of elastic deformation characteristics, people use it for seal up and impermeable of construction, features anti-ero sion, good durability wear durableness.
