1) light weight, large expansion strength, no water absorption (instead of the traditional three oil, four blankets, asphalt, wood, fir and other materials). Product environmental protection, simple construction, seepage control, leak proof, water stopping effect is good.
2) corrosion resistance, aging resistance, high and low temperature, +80 DEG C, ~-45 DEG C, no flow, no deformation, no brittle crack, long service life.
3) with independent hole bubble structure, special type of joint plate appearance of honeycomb holes evenly distributed, without a hair can be with the cement / sealants are tightly bonded together, adapt to the natural expansion and shrinkage changes, enhance sealing expansion sealing effect.
