Product Overview
Butyl waterproof tape is a permanently non-curing self-adhesive sealing tape manufactured from butyl rubber as the primary raw material, compounded with auxiliary agents via advanced processing. It delivers exceptional adhesion to various substrates while offering superior weather resistance, aging resistance, and waterproofing. This solvent-free product provides permanent sealing, vibration damping, and protective functions without shrinkage or toxic emissions. Its permanent tackiness ensures excellent conformability to substrate thermal expansion/contraction and mechanical deformation.
Key Features
-
Self-adhesive application: Forms continuous uniform seals without heating or pressure. Conforms perfectly to irregular surfaces.
-
Chemical resistance: Excellent corrosion protection for metal substrates and cable surfaces.
-
Permanent flexibility: Maintains elasticity without hardening. Resists tearing while retaining waterproof integrity during movement.
-
Dual barrier function: Superior waterproofing and vapor sealing performance.
-
Wide temperature tolerance: Effective across -40°C to 90°C service range.
