Hybrid Joint NS-LL Type: A Stretchable Device with Excellent Water Stopping Properties
The adhesion between the steel plate and rubber was confirmed to have no delamination in the tensile test!
The Hybrid Joint NS-LL type is manufactured using the press vulcanization bonding technology, which is also used in the production of bearings. Regarding the bonding part, it has been confirmed through a tensile test by the Chemical Substance Evaluation Research Organization that the failure mode was material failure rather than cohesive failure, meaning there was no delamination. This indicates that the steel plate and rubber are bonded very strongly, making it a product with excellent water-tightness. In addition to the strong adhesive force between the rubber and the steel plate, the structure is designed so that the water-stopping rubber does not come into direct contact with the tires of passing vehicles, making it less prone to wear. The range of products available includes both small and large items, accommodating expansion amounts from 20mm to 175mm and a maximum applicable slab gap of 395mm. **Features** - High water-tightness - Steel vertical tooth shape - One-lane assembly product ~~ We are currently seeking agents! Agents from the Tohoku and Hokuriku regions are very welcome! Of course, we also accommodate companies from other regions! ~~ For more details, please contact us or request a catalog.
