Plastic designers need more-efficient, reliable, and economical ways to join LSE plastics, while specifying more LSE plastics. It is found that plastics with relatively high surface energy such as acrylonitrile butadiene styrene (ABS) and polycarbonate, bond readily as they are easily wet by conventional adhesives. Engineers can make LSE plastics easier to bond by either raising the surface energy of the plastic or lowering the surface energy of the adhesive. Lowering the surface energy of the adhesive to attain an aggressive bond, involves adding tackifiers to the adhesive formulation. Engineers also use double-coated or transfer tapes to improve tackiness. The high-strength, one-part adhesives cure at room temperature and produce strong bonds on LSE plastics without olefin primers. Cure strength can be increased further with plasma, primer, or corona discharge pretreatment of the LSE plastic. Source

Large area bonding applications have grown considerably since then as designers recognized the performance, production, and cost advantages of adhesives over other fastening techniques. Contact adhesives are applied to both mating surfaces and allow ed to dry. When the surfaces are pressed together, a strong bond forms immediately. While solvent based formulas dry quickly, there are health, safety and environmental concerns with their use. Another option is one-part, water- based neoprene contact adhesives. These fast tacking adhesives strongly bond foam to foam in 15 seconds or on contact if an activator is used. Aerosol adhesives are used for bonding lightweight materials, including fabrics, plastics, flexible foams, paper, cardboard and thin-gauge metals. Sprayable hot-melt adhesives hardens and reaches ultimate bond strength in seconds. These adhesives have higher heat resistance, the ability to bond low-surface energy plastics, good environmental and electrical resistance, low viscosity for high flow rates and increased production.

The market for surgical drapes and ostomy applications is growing and medical device OEMs should take advantage of flexible materials converting and adhesive expertise. Ostomy or drape medical devices can be manufactured with the help of polystyrene, polycarbonate, acrylics, silicone rubber, polyethylene, polypropylene, and synthetic rubbers. New adhesives delivered via liquids or thin film pressure-sensitive adhesive (PSA) systems produce strong bonds with low surface energy (LSE) plastics. Surgical drapes used in surgical procedures are are often designed to soak up spills and splatters while not allowing fluid strike-through. Double-coated tapes can feature a gentle adhesive on one side and an industrial strength adhesive on the other. Film double-coated tapes offer secure adhesion and are easy to clean for applications in ostomy and continence devices. A converter can provide extensive label printing capabilities for tamper-evident and custom pressure-sensitive labeling of medical devices. Source

Designers of aircraft and ground transportation vehicles are increasingly using innovative adhesives in place using innovative adhesives in place of traditional fasteners to withstand harsh environments. Designers also are using thin-film bonding products, such as pressure-sensitive foam tapes and adhesive transfer tapes. These products are being preferred by designers, as they are better than rivets, spot welds, thermal joining, rigid liquid adhesives and other permanent fasteners for joining substrates such as metals, plastics, rubbers, and glass. The main advantages of these adhesives and thin-film bonding products include distributing in place of concentrating stress loads, accommodating flex and vibration, and separating potentially reactive metals. Designers can choose from several types of liquid adhesives and flexible thin-film bonding systems that resist environmental stress and degradation. Source

Engineers need to gather information about some of the aspects of different types of foams to achieve better results from them. These professionals have realized that working with foam requires partnering with a materials converter experienced in the varieties and capabilities of foam. They need to know that foam is formed by trapping gas bubbles in a liquid or solid. Solid foams are open or closed cell and pores are connected to each other in open-cell versions, forming a relatively soft network. There are many variations of foams, including flexible, rigid, reticular, rate responsive, and syntactic, with new types of foam being continually developed. Flexible foams are useful when users need a material that bends, flexes, or absorbs force without damage or delamination, while rigid foams have a matrix structure that gives them little or no flexibility. Reticulated foam has the window membranes of each cell removed, leaving only a skeletal structure and it can be reticulated by zapping or quenching. Source
