PZ Product Type Water Contact Expansion Waterstop
Reliable water stopping performance: Once in contact with the immersed water, its volume expands rapidly to achieve complete water stopping. Safety of construction, easy to adapt to the deformation of the structure because of the elasticity of the recovery force.
Product Description
Product features
Reliable water stopping performance: Once in contact with the immersed water, its volume expands rapidly to achieve complete water stopping. Safety of construction, easy to adapt to the deformation of the structure because of the elasticity of the recovery force. Applicability to a wide range: it can be used in various climates and under various conditions of components. Excellent environmental protection: excellent chemical medium resistance and durability, no harmful substances, no pollution of the environment. Its expansion multiplier (%) can be divided into several categories: ≥150%～<250%, ≥250%～<400%, ≥400%～<600%, ≥600%, etc.
