What is Butyl Seal?
It is an extruded sealant mainly made of butyl rubber. It combines the elasticity of vulcanized rubber and the plasticity of putty-like sealant at the same time, and can be bonded to objects of any shape to make it completely waterproof. In addition, it has excellent chemical resistance and weather resistance, so it is used in all fields.

* Sheet-shaped butyl seals have different physical properties.
merit
- ・ It combines the elasticity of vulcanized rubber with the plasticity of putty-like sealants.
- ・ Deforms and improves the degree of sealing, making it a completely waterproof body.
- ・ Excellent weather resistance and chemical resistance.
- The product itself is adhesive.
demerit
- ・ Once glued, it will not come off. (Or it doesn’t come off cleanly)
- ・ Since it deforms when loaded, it is not suitable for specifications.
- ・ Hardens and softens depending on temperature.
- ・ Made-to-order products other than sheet form. (Non-standard items require a mouthpiece)
Construction example
- ・ Waterproofing of joints of concrete products such as manholes
- ・ Sealing tape for roofs, floors, glass surrounds, etc.
