Water‐swellable rubber (WSR) comprises super absorbent polymer (SAP) embedded in a rubber matrix and has been commonly used as sealants and caulks, in which high water uptake and sufficient mechanical strength are required. In this work, we investigated the swelling behavior and mechanical properties of rubber composites comprising SAP powders. A reinforcement effect is caused by the SAP particles, which are described using a modified Guth–Gold equation up to the semi‐dilute region. The complex modulus shows upper deviation at high SAP content owing to network formation between SAP particles. The swelling force of the WSR is explained by the amount of SAP particles in the surface layer of the matrix up to the semi‐dilute region. The formation of the SAP network leads to an appreciable increase in the swelling force of WSR, as SAP particles embedded in the matrix also contribute to the swelling of WSR. © 2019 Wiley Periodicals, Inc.
