Abstract

This article provides comprehensive experimental data of two polymers for shield tunnel sealing gasket: i) water swelling polyurethane (WSP) and ii) a mixture (WSRP) of WSP and water swelling rubber (WSR). Water-swelling tests are conducted to investigate the microstructural changes and properties of both WSP and WSRP during water swelling. These data can be useful for the quantitative evaluation of water swelling performance of WSP and WSRP. The data presented herein was used for the article, titled "Experimental investigation of water swelling characteristics of polymer materials for tunnel sealing gasket" [1].

Keywords: Compatibility; Micro-structure; Swelling capacity; Thermal stability; Water swelling polyurethane; Water swelling rubber.
