The seamless rubber dam produced by Yantai Tiansheng Rubber Dam Group Co.,Ltd, a new generation product self-developed on the basis of the first and second generations of seamless rubber dam, is the first seamless rubber dam produced in China.

The research and application of the seamless rubber dam has been certified as the international advanced technology by Water Resource and achieved national invention patent and utility model patent.    Seamed rubber dam is formed by hot-sticking mechanical modeling technique after single-width vulcanization under certain pressure and temperature. The producing technique is to glue canvases, vulcanize them into single-width gluing board, connect them and finally join them into bag dam. 

It has such advantages as follows:

1. the adhesive tapes of seamless rubber dam bag are overlapped in dislocation. After finishing rolling process, the whole dam bag is vulcanized and modeled by large thermo-compression vulcanizer.2. It makes the canvas forced directly, which improves dam bag forcing condition, latitudinal tension and the safety.3. It has an excellent integration that can reduce water fluctuation press-sure, improve earthquake-resistant behavior to avoid resonance in case that water overflows the dam, dam bags would be damaged.4. The dam bags could be built in one piece, which improves the overall quality, fatigue resistance, flexing life and working life and. Under same condition, its inner pressure ratio could be improved by 0.05 and building cost also saved 5%.5. It can be installed mechanically, which greatly reduces the labor strength and improves working efficiency and saves installation expenses.6. the whole dam bag is even with the same thickness and no adding pad so that materials and installation costs are saved.7. Dam bag is perfectly integrated without seam appearing on its surface, which greatly improves its anti-pierce performance and reduces the piercing and tearing ratio of dam bag.
