Water swelling rubber sealing strip is made of rubber polymer, inorganic materials and water swelling rubber and synthetic additives with adhesive properties of a new building waterproof material. With water absorbing volume expansion, squeeze the gap between the density of old and new concrete, the formation of plasticity colloid impermeable. The product has created a new way for the to solve the leakage problem of construction gap bridge construction or concrete high-rise building, to fill a gap in China's waterproof. The quality of the products has reached the world advanced level.
The products in Beijing in June 1988 by the Ministry of science and technology achievements appraisal, won the 1991 National Award, in order to solve the concrete construction joints, pouring seam leakage problems and create a new way to fill a gap in waterproof materials in China. The quality of the products has reached the world advanced level. The technology transfer of our company after several years by more the strict theoretical analysis, scientific experiments and solicit suggestions of users, we have developed BW- type, BW- type, BW- type, BW- (slow expansion) type IV (slow expansion seal), formed to adapt to different engineering conditions to perfect water swelling self-adhesiveThe rubber sealing strip.
