Butyl rubber waterproof sealing adhesive tape is made of butyl rubber and polyisobutylene and other main raw materials. According to the production formula, science and technology are adopted, special polymer materials (imported) are selected, and environmentally friendly solvent-free sealing bonding materials are produced through a special process process. (1) Excellent mechanical properties: butyl tape has high bonding strength, tensile strength, good elasticity and extensibility, and strong adaptability to interface deformation and cracking. (2) Stable chemical performance: butyl tape has excellent chemical resistance, weather resistance and corrosion resistance. (3) Reliable application performance: butyl tape has good adhesion, waterproof, sealing, low temperature resistance and followability, and good dimensional stability. (4) The construction and operation process of butyl tape is simple (1) roof waterproofing, underground waterproofing of new projects, waterproof treatment of structural construction joints, and lap sealing of polymer waterproof membranes. (2) It is used for sealing and waterproofing of construction joints of subway tunnel structures in municipal engineering. (3) Airtight, waterproof, shock absorption at the joints of the color pressed plate. Airtight, waterproof, shock absorption at the butyl tape joint in the sunshine board project. (4) Bonding and sealing treatment in automobile assembly (5) Waterproof sealing treatment at the junction of steel structure construction (6) Butyl tape with composite aluminum foil is suitable for waterproof sealing of various civil engineering roofs, color steel, steel structures, waterproof membranes, PC boards, etc. under sunlight
