![]() What stresses or loads will be present in the application? The forces that often act on tapes include shear, tensile, cleavage, and peel.Are there any gaps to fill? The tape must have the right gap filling ability for any uneven or non-planar surfaces.Different classes of materials act very differently when bonding. You have to identify what you want to bond together so you pick the best candidates. What materials are you bonding? There is no “one size fits all” with double coated tapes.What is the end use and what are you trying to accomplish? This is the short “elevator pitch” question.Nonwovens Matching Tape and Application- Important Questions to Ask ![]() Polyurethane UPVC (unplasticized polyvinyl chloride) Electrical/ and thermal conductivity or insulationĬommon Foam Carriers Common Film Carriers.These properties impact the selection of the best tapes for a given application. Photo Courtesy of 3M Types of Carriers and ImpactĬarriers or backings are an important element of the double coated tape as they have a significant influence on the physical properties and the ultimate performance of the tape. A release liner can be applied to both sides of the tape or more often a double siliconized liner is used that allows the tape to be wound on itself (also referred to as self-wound). Defining a Double Coated (Sided) TapeĪ double coated or double sided tape is a specific tape format wherein a pressure-sensitive adhesive is coated onto both sides of a carrier or in some cases with acrylic foams – a foaming agent can be incorporated into an adhesive matrix and then” foamed” so the resulting tape is monolithic but in fact has adhesive on both sides. Having said that, it is possible to talk about certain double coated tape products that do a lot of things very well and are excellent “go to” products when considering bonding and assembly applications. Here’s the spoiler tapes are one of those things and answering the question about “the best” tape overall is technically impossible. For other things, it’s not nearly as easy. There are agreed upon rules and competitions that can be held and the team or individual that has the best results is the winner. With sports, it’s not as hard to answer that question.
