When you choose to use adhesive tape rather than the regular tape, you most probably want to bond two surfaces together. And adhesive tape is a reliable tool to do this, because it contains adhesive film and certain material that make it possible for objects to join or bond together instead of using screws or fasteners. Its application over mechanical fasteners helps you use lower temperature applications for easier manufacturing processes. With this, the surface area involved will be protected since you no longer have to damage the surface with the use of screws or fasteners.
Adhesive masking tape is a great solution for the production of automated product, as compared to liquid adhesive which is time consuming and a bit messy because it need to be rolled or to be sprayed into the area before bonding took place. The Market of Adhesive Tapes There are only four major players in the tape market industry and they are the following: water activated tape, gummed paper tape or gummed tape, heat activated tape, pressure sensitive adhesives (PSAs), and non-adhesive tapes. This article will provide an overview of these four types. Water activated tape, gummed paper tape or gummed tape. This type of tape is made of starch or an animal glue-based adhesive on a kraft paper backing that when moistened becomes sticky. This water activated tape is used for sealing and closing boxes and it is very affordable. For boxes, the tape applied is moistened first by water before sealing and closing them. Heat activated tape. This type is often free from tack until activated with heat source. When using this type of tape, make sure that you have available time or not is a hurry because it requires time at elevated temperatures of 180˚ or higher to achieve better bond. Adhesive tape that is heat-activated allows the aggressive bonding of difficult surfaces including PVC-based plastic materials, EPDM, PU, and rubber. Pressure sensitive adhesives (PSAs). PSAs have slightly sticky feel at room temperature in dry form. They are firm and can stick fast to different a dissimilar surfaces, application using a finger or a hand may be used. As previously stated, PSAs don’t need water, heat or solvent to function as double sided tape adhesive that bond with paper, metal, wood, cement, glass and plastic. You need to put additional bonding to it for ensured bonding. Its temperature should be at a moderate temperature between 59º F and 95º F. Avoid applying low heat temperature because this may lead to insufficient “coverage.” Also watch-out on the use of high temperature since this may caused the tape to stretch when applied. Non-adhesive tape. Non-adhesive films, laminates or tapes do not use applied adhesive because they are self-adhering. A good example for this type is PTFE thread-sealing tape. If you need further information about these four major types of adhesive tape, you can go online and do research related to its development, studies and technological innovation. Also look for details about its various usages.
