What is Adhesive Tape?
Generally, we use fasteners, screws or welding to join or fix things together. Adhesive tape is one the suitable option to fix the objects. Using adhesive tape enables the worker to use the lower temperature application. This automatically makes the production easy. Fasteners or screws can cause harm to the surface, whereas adhesive tapes can protect your surface area. You can rely on adhesive tapes during the production of automated products.
What are they made of?
Different kinds of backing or carrier are used to make the adhesive tape like paper, plastic film, cloth, foam, foil, etc. Sometimes a release liner is also used. Then the procedure goes on and it is rolled in the jumbo roll of tape. Furthermore, coming to the last stage they are cut into small width bands to make many rolls. The composition of the roll varies on its use, as different bonding solutions are required for different purposes.
USES: It can be used for various purposes depending upon your need. Select a type that meets your needs. The various varieties are for sticking to other surfaces; consequently, determine your requirements and temperatures.
Most Popular Type of Adhesive Tape
Pressure-sensitive adhesives (PSAs)
This tape is a thin flexible material with a single or double side coating. It is used at a moderate temperature usually in dry form. You do not need to use any water or solvent for its working. It can maintain bonds to materials such as paper, plastic, glass, wood, cement and metal without any heat activation. They are widely used as their application is easy with a finger or a hand. You must keep in mind that that low temperature can lead to the wetting or coverage of the adhesive. Whereas high temperatures can cause extra stress.
• Thinner and lighter materials
• Dissimilar materials can be joined without fear of incompatibility
• Vibration dampening and noise reduction are provided
• Assembly time is cut in half
• Surface refinishing is no longer necessary
This tape requires a heat source to serve its purpose. To achieve binding, the heat-activated tape must be exposed to temperatures of 180°F or higher for an extended period. Heat-activated adhesives can adhere to a variety of tough surfaces, including rubber, EPDM, PU, and PVC-based plastics. It can be built with many carriers to suit a wide range of applications.
• It can be made firm or flexible depending on the use
• Adhesion is excellent
• Excellent for sealing and induction curing
• Durable washing machine
• Bonding of EPDM extrusion profiles for the automobile industry
Water-activated tape/ Gummed Paper Tape
This tape is generally based on starch or animal-glue based adhesive tape. The kraft paper on its back gets sticky after getting wet. It is a low-cost option for sealing and closing boxes.
• A powerful, secure binding is formed when wet glue interacts with porous surfaces.
• If an attempt is made to remove the tape before delivery, it will tear.
• Because of the paper's ease of handling, it's perfect for hand applications.
• Without the use of cutting tools, the boxes are securely sealed but easy to open.
• Rolls with no cores save time and effort when changing rolls.
Because they are self-adhering, non-adhesive tapes, films, or laminates do not have an applied adhesive. Example: Thread-sealing tape made of PTFE.
