Execution Standard: GB/T 18173.3 "Polymer Waterproofing Materials - Part 3 Water-Swellable Rubber" The self-adhesive water-swellable sealing strip is a flexible water-swellable sealing material with a built-in pressure-sensitive adhesive layer. It uses synthetic rubber (butyl rubber/nitrile rubber) as the elastic matrix, compounded with superabsorbent resin, bentonite, and other swelling components. One side is coated with high-adhesion…

The water-expanding sealant strip is also known as the water-expanding rubber sealant strip for use in situations where water comes into contact with it. It is a strip-shaped sealing material with water-expansion properties, which is made through compounding and extrusion using more than ten types of materials.The water-expanding sealant strip has a high expansion rate and strong self-repairing ability. When placed at the construction joint, it h…

Execution Standard: GB/T 18173.3 "Polymer Waterproofing Materials - Part 3: Water-Swellable Rubber" The product-type water-swellable sealing strip is a rigid water-swellable sealing material that has undergone high-temperature and high-pressure vulcanization. It uses natural rubber/nitrile rubber as the elastic matrix, compounded with superabsorbent resin, sodium bentonite, and other core swelling components. It combines the dual functi…

Basic Definition and Core PrinciplesDefinition: A shaped waterproofing material made primarily from polymer resins such as PVC (polyvinyl chloride), HDPE (high-density polyethylene), and EVA, through mixing, granulation, and extrusion molding. It is used for waterproofing construction joints, expansion joints, and deformation joints in concrete structures.Core Principle: Utilizing the elastic deformation characteristics and density of plastics, i…
