NEOMAX SWELL-P

Water-Expanding Rubber Based on Polyurethane

NEOMAX SWELL is a water-expanding rubber based on polyurethane, which is available is several different types. NEOMAX SWELL is used for sealing purposes in civil engineering, structural engineering as well as tunneling.

PROPERTIES

NEOMAX SWELL has the distinction of a three dimensional polymer structure, which is build up from unstructured polyurethane chains (macromolecules).

The elastomeric features arise due to the weak cross linkage of the polymer chains.

The swelling ability happens due to hydrophilic polymer resins, which can expand in contact with water up to approx. 450 % in volume.

In order to avoid an early mechanical loading of surrounding fresh concrete by excessive swelling pressure the swelling process is slow and controlled (see volumetric expansion process).

NEOMAX SWELL is used for sealing of construction joints, pipe penetrations and precast concrete elements such as shaft rings, tubbings etc..
