In construction applications, butyl tape and putty tape are both popular. Because of their similar appearance and use, many people mistakenly regard them as the same product. There are obvious differences between the two.
Next, we will give you a detailed comparison of the differences between butyl tape and putty tape, as well as their respective advantages.
Butyl tape and putty tape are different in composition
Butyl flashing tape uses butyl rubber as the main component, and adds some tackifiers, antioxidants, fillers, etc. Tackifiers can improve the adhesion of the tape and make it stick better on a variety of surfaces; Antioxidants can delay the aging speed of adhesive tape and prolong its service life; The filler can improve the physical properties of the tape. After several kinds of raw materials are mixed in proportion, they are plasticized in a high-temperature environment. Then, through the extrusion process, the mixed rubber is made into adhesive tape of specific thickness and width, and finally covered with isolation paper for easy storage and use.
Putty tape is mainly composed of high molecular polymer, filler, plasticizer, and solvent. Polymers provide viscosity and flexibility, fillers increase volume and improve performance, plasticizers improve softness and plasticity, and solvents are used to dissolve other ingredients for easy processing. During production, the high molecular polymer is first dissolved in a solvent to form a solution, and then additives such as fillers and plasticizers are added and stirred evenly. Then, the glue is evenly coated on paper, fabric, and other materials, and then dried and cured to make putty tape.
Butyl tape and putty tape differ in appearance
Butyl tape has a smooth and delicate surface, and it is available in single-sided and double-sided types. Its back is often made of aluminum foil or non-woven fabric, which can not only enhance the toughness of the tape, but also improve the ultraviolet resistance. The adhesive tape has no added solvent, no irritating smell, and good environmental protection performance in the production process.
The surface of putty tape has a grainy or embossed pattern, and it is also divided into single-sided and double-sided. However, some putty tapes containing asphalt can emit a pungent smell.
Butyl tape and putty tape differ in performance
Butyl tape has soft texture, good elasticity, strong viscosity, and stretches without a continuous filament. It is suitable for various shapes and surfaces, has excellent durability, does not dry after long-term use, and can closely fit objects. Maintains a long-lasting waterproof seal in the face of material deformation or expansion joints.
Compared with butyl tape, putty tape has a slightly harder texture. It also has strong viscosity and fast drying speed, which can complete the sealing operation in a short time, saving valuable time for construction.
Butyl tape and putty tape differences in application
Butyl tape can be adhered to a variety of material surfaces, such as glass, metal, concrete, wood, plastic, rubber, etc. The main application scenarios include:
Roof waterproofing: It can be used to seal the overlap of color steel tile roofs and gutters to prevent rainwater leakage; It can also repair the leakage points of concrete or EPDM roofing to ensure the waterproofing effect of the roof. Additionally, butyl tape can also be used at the joist and chimney joints to create a tight seal.
Window sealing: During the installation or use of windows, butyl tape can fill the gaps and play the role of sound insulation, heat insulation, mosquito prevention, and waterproofing.
Pipeline sealing: Used at the interface of various pipelines to prevent liquid or gas leakage in the pipeline and ensure the normal operation of the pipeline system.
RV: Butyl tape can provide an excellent sealing effect for RV windows and other parts of the roof, effectively blocking the intrusion of wind, rain, and dust, and can also play a certain role in sound and heat insulation, creating a comfortable and safe interior environment.
Ship: In the ship’s pipeline system, deck gaps, valves, vent windows, and other parts, butyl tape can play a waterproof, moisture-proof, and dust-proof role to ensure the normal operation of the internal equipment of the ship.
Putty tape can be adhered to glass, plastic, and metal. Its main application scenarios include:
Wall repair: Putty tape can repair wall cracks, fill potholes, etc.
Pipe sealing: In indoor piping systems, putty tape can effectively seal pipe joints to prevent liquid or gas leakage.
Window sealing: Putty tape is used to seal the edge of the window, enhance the sealing of the window, block the intrusion of wind, rain, and dust, and improve the indoor heat preservation and sound insulation effect.
Temporary repair of roof waterproofing: When there is a slight leak in the roof, putty tape can be used as a temporary repair material to quickly prevent rainwater from penetrating and buy time for further repairs.
Summary
The above is a comparison of butyl tape and putty tape. Of course, they also have a lot in common. They have good sealing and adhesive properties and certain waterproof effects. When used in construction, industry, and other fields, they can provide reliable protection for materials and equipment.
If only simple sealing is required, putty tape is a more economical choice, and its cost is relatively low. For scenarios that require long-lasting sealing, butyl tape is more suitable. It can eliminate frequent maintenance during long-term use.
