For leak prevention! A sealing material that expands upon contact with water to exhibit water-stopping effects.
"Best Seal EW" is a sealing material that, upon contact with water, expands due to self-expansion pressure, completely sealing the water paths in joints or connections and demonstrating a waterproofing effect. The water expansion effect can be repeated semi-permanently, helping to prevent leaks over long periods. It is based on highly durable chloroprene rubber (CR), which possesses excellent rubber elasticity (restorative power) and swells in water, easily adapting to variations in joint spacing. Additionally, the expansion ratio due to water can be easily adjusted, allowing for the selection of sealing materials tailored to specific purposes. 【Features】 ■ The sealing material expands upon contact with water, demonstrating a waterproofing effect ■ Made from highly durable chloroprene rubber ■ Excellent rubber elasticity ■ Adapts to variations in joint spacing ■ Allows for the selection of sealing materials according to purpose *For more details, please refer to the PDF document or feel free to contact us.
