| 【Other Features】 ■ This non-fluorocarbon product uses HFO, the industry's first blowing agent, which is environmentally friendly, has minimal volume shrinkage, suppresses internal temperature rise, and prevents smoke accidents. ■ It expands and cures up to 40 times and cures in one minute, allowing for construction without being affected by groundwater. Additionally, it reduces the risk of leakage accidents during injection, ensuring safe construction. ■ It can be applied using a battery, making it possible to work in narrow areas where generators cannot be brought inside, in locations where electrical wiring work is difficult, or in places where the operation of generators with internal combustion engines is not feasible. ■ With over 1,000 successful applications of 40 times expanded polyurethane, it holds the number one record in domestic achievements. ■ A responsible construction system backed by over 30 domestic association members allows for high-quality construction anywhere in the country. ■ The average increase rate of the final injection volume is 132%, making it more economical compared to other injection materials. ■ It features an isocyanurate bond with excellent heat resistance and flame retardancy, making it a safe construction method with no recorded smoke accidents in tunnel backfill injection work. ■ The compact injection equipment does not require wide access roads or land, allowing for easy construction. *For more details, please download the PDF or feel free to contact us. | Please feel free to contact us. | ||
