Butyl waterproof tape is a kind of lifetime non-curing self-adhesive waterproof sealing tape made of butyl rubber as the main raw material, with other additives and selected polymer materials through advanced technology. It has excellent adhesion strength and excellent weather resistance, aging resistance and water resistance. It has the functions of sealing, damping and protecting the surface of the adherend. The product is completely solvent-free, so it does not shrink or emit toxic gases. Because it does not solidify for life, it has excellent follow-up to the thermal expansion and contraction of the surface of the adherend and mechanical deformation. It is an extremely advanced waterproof sealing material. Butyl tape, or butyl tape, is a material used in waterproof, moisture-proof and sealing.
