Extrusion molding with an extruder and mold forming with a press are possible! Adjustment of the expansion rate is possible.
"Water-swelling rubber" is a product that has been applied as a waterproof material in the civil engineering and construction fields, utilizing its characteristic function of expanding (volume expansion) when in contact with water. In sewer systems, it is used as rubber rings for joints of Hume pipes and PVC pipes, and in tunnel construction (shield method), it is used as segment sealing material. Additionally, it can be utilized as a water stop material in joint trenches for electricity, gas, and other places requiring water stopping. 【Features】 ■ Water swelling function: Expansion rate can be adjusted ■ Molding method: Can be formed by extrusion using an extruder or by mold forming using a press *For more details, please refer to the related links or feel free to contact us.
