What is Expansion Joint TPE Band ?
TPE (thermoplastic elastomer) expansion joint lap Tape is a polymer material product used for sealing and waterproofing joints in structures such as buildings and bridges. It mainly utilizes the unique properties of TPE material to adapt to the expansion and displacement changes of joints, and plays a long-term sealing and waterproof role.
To give you a more intuitive understanding of it, the following table compares it with another common seam material:
| Feature dimension | Expansion Joint TPE Band | Traditional rubber waterstop |
| Core materials | Thermoplastic elastomers (TPE/TPO, etc.) | vulcanized rubber |
| Physical properties | High elasticity and deformation recovery ability, able to effectively follow the expansion and contraction of joints. The hardness range is wide and can be adjusted through formula. | Good elasticity, but some formulas may have a higher permanent deformation rate. |
| Weather resistance and durability |
It has excellent UV resistance, ozone resistance, acid and alkali resistance, and strong anti-aging ability.
|
The aging resistance depends on the formula, and high-quality products also have good performance. |
| construction technology | Flexible process: often designed as self-adhesive, easy to install; Some parts can be seamlessly connected through hot pressing and hot air welding. | Mainly relying on pre embedding and on-site bonding, with high process requirements. |
| environmental friendliness | Recyclable, the production process generally does not require vulcanization, making it more environmentally friendly. | The sulfurization process has high energy consumption and relatively difficult recycling. |
Main application scenarios
TPE expansion joint overlap tape is widely used in various types of joints that may experience displacement and require flexible sealing, such as:
◉ Underground engineering: expansion joints and construction joints for tunnels, basements, and comprehensive pipe galleries.
◉ Road traffic: Expansion joints of bridges, elevated roads, and roads.
◉ Construction engineering: concrete exterior wall panel joints, prefabricated component connection joints, roof joints, etc.
