BW water swellable rubber seal for a wide range, can be used for all projects can be used to replace the traditional seal, products of traditional products, plugging the gap of water swelling, water sealing, prevent leakage of reliable results. Resistance to water pressure, water swelling rate is appropriate, has many functions. With the expansion of self adhesive, can be directly used paste in part or with high-strength steel nail positioning. Products with inorganic materials, aging resistance, corrosion resistance, has remarkable self-healing function, when the construction joint or deformation of foundation settlement and cracks, the water stop can continue to swell, blocking the new gap, strengthen the automatic proofWater effect.
Yichun expansive rubber seal of how much water. Macheng water swelling rubber sealing company. This product has water swell, "water seal" role; with swell speed is slow, the swelling ratio is less than or equal to the maximum 186h water swelling ratio of 50%; the commodity unit construction convenience, low price and no pollution in when the length of immersion under no dissolved out; and other hydrophilic waterstop swell largest are hydrophilic it by repeated swell swell after a long time is not lost.
