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…

Waterstop adhesive is a paste-like single-polymer elastic sealant, mainly made of polyurethane as the core matrix, compounded with water-swellable resin, tackifier, curing agent, anti-aging additives, etc. It has both elastic sealing and water-swellable sealing functions. Some models can be self-leveling/non-sagging, and are suitable for different construction surfaces. Compared with waterstop strips, it is more suitable for caulking and sealing …

Rubber bearings are core load-bearing, seismic isolation, and displacement adjustment components in bridges, buildings, and municipal engineering. Made with natural rubber/chloroprene rubber as the elastic matrix and composite thin steel plates, polytetrafluoroethylene (PTFE) plates, and structural steel, they possess four functions: vertical load-bearing, horizontal displacement, angular deformation mitigation, and shock absorption. They effecti…

A water-blocking airbag (also known as a pipe sealing airbag, water-closing plug, or inflatable pipe plug) is an inflatable sealing tool made of high-strength rubber and fiber fabric composite. By inflating, the airbag expands to fit tightly against the inner wall of the pipe, using friction and elasticity to form a temporary sealing barrier and quickly stop water flow. It is an ideal tool for underground pipeline drainage, sludge treatment, and …

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…

Polyethylene closed-cell foam board (PE closed-cell foam board for short) is a polymer material with an independent closed-cell honeycomb structure, made from polyethylene (PE) or cross-linked polyethylene (XLPE) as the base material through chemical or physical foaming processes. Its core characteristic is that the internal air bubbles are isolated from each other, forming a dense protective barrier. It possesses multiple properties such as ligh…

The sealant not only has strong adhesion but also good durability and strength.5. Resistant to UV rays, agin…

Automotive glass glue is a specialized type of automotive sealant, specifically designed for bonding and sealing automotive glass (windshield, side windows, rear window) to the vehicle's metal frame, and headlight glass to the headlight housing. It combines structural bonding strength with sealing and protective performance, making it a key material for ensuring the secure installation of automotive glass and preventing water leakage, dust in…

Single-component polyurethane building sealants are moisture-curing polyurethane sealants specifically designed for building engineering. They are made with modified polyurethane prepolymer as the core base material, compounded with weather-resistant additives, adhesion promoters, fillers, etc., and are manufactured in strict accordance with national standards. They are ideal for sealing, waterproofing, and resisting structural deformation of var…

Type II natural rubber bearings consist of a layer of steel frame plate and a layer of functional rubber. The steel plate provides vertical load-bearing capacity, while the rubber ensures the horizontal flexibility of the seismic isolation bearing. Protective rubber provides protection against aging and other defects for the internal functional rubber.…
