Swelling waterstop in case of seawater
PN--H type water expansion waterstop is a new product successfully produced by our company based on the original PN(BW) water expansion rubber which can not expand in seawater and water containing heavy minerals, after years of research and repeated testing by our scientific researchers.
Product Description
PN--H type water expansion waterstop is a new product successfully produced by our company based on the original PN(BW) water expansion rubber which can not expand in seawater and water containing heavy minerals, after years of research and repeated testing by our scientific researchers.
PN--H type water expansion strip can be expanded in seawater and complex water quality, and the effect is better than PN (BW) water expansion strip technical indicators, can be used in various climates and various conditions of the components, has been applied to the Huangdao dock project, proved that the water stopping effect is good.
PN--H type seawater expansion waterstop is suitable for concrete construction joints, expansion joints, subway, ****, basement, water treatment, etc. This product has good resistance to chemical media, does not contain harmful substances, does not pollute the environment, expands when encountering seawater, stops water with water, and stops leakage effectively. Its expansion multiplier can be divided into several categories: ≥200%, ≥300%, ≥600%, etc.
