"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.

"Thermal Expansion Fireproof Putty" is a flexible and easy-to-work-with thermal expansion fireproof material. It begins to expand thermally at 200°C due to heat during a fire, expanding its volume by 6 to 10 times. After thermal expansion, it maintains a solid shape and completely seals any gaps. This product does not contain harmful components such as asbestos or halogens. 【Features】 - Flexible and easy to work with - Maintains shape and completely seals gaps - Does not contain harmful components such as asbestos or halogens *For more details, please refer to the PDF document or feel free to contact us.

"Thermal expansion fireproof rubber" begins to expand at temperatures above 200°C, forming a strong insulating layer, and the expanding material fills gaps to exhibit smoke-blocking effects. It is available in flexible tape and sheet forms, offering excellent workability. Various molding methods such as press molding, extrusion molding, and calendar molding are possible. Additionally, by applying double-sided adhesive tape (paper, butyl seal), installation on ceilings and walls can be easily accomplished. 【Features】 ■ Excellent fire resistance ■ Easy-to-handle shape ■ Non-halogen type with extremely low generation of toxic gases ■ Soundproofing and vibration-damping properties ■ Workability *For more details, please refer to the PDF materials or feel free to contact us.
