Film and sheeting applications for soft TPV grades include surgical drapes, dental dams, and elastic tapes for wound care in the medical and healthcare arena waist band tapes for clothing and elastic geomembranes in building and construction (Mapleston 2007). 

Elastic tape is an elastic cotton strip—a highly elastic, fiat, braided band containing rubber or elastomeric fibers. 

Buttonhole tape is a broad elastic tape with buttonholes located in the center. 

The solution for an oil-resistant elastomeric rubber composite particularly suitable for use as an elastic tape for garments has been found in a blend of NR,... 

For measurement of values a very simple, reliable tool is a piece of elastic tape marked with ten equal calibrations and subdivisions (0 to 1.0). This can be mounted with the zero end held fast to a strip of metal and a movable clamp attached to the opposite end of the tape. The 0 is positioned at the origin and the 1.0 placed at the front. The R p can then be read directly from the scale opposite the antibiotic zone. 

There are several technologies to combine single fibres to sensor modules. On the one hand, knitting allows one to tie the fibres tightly, without risking influence on the functionality. On the other hand, enwinding allows one to work conductive elastic threads into elastic tapes. It also allows for an adjustment of the force-dilatation ratio in the fibre.

PSA compositions must have a good balance of different properties, depending on its specific application. PSAs for adhesive tapes for instance, must have a good adhesion, cohesion, stretchiness and elasticity. Furthermore the base polymers must be elastomers at room temperature [124]. Due to its elastomeric behavior and biodegradability, poly(HAMCL) seems to be a promising base polymer for the development of a completely biodegradable PSA. 

PEN him is like PET film, but superior in various properties, and is finding wide applicahon for magnehc tapes. Weick and Bhushan have compared the dynamic mechanical properties and wear/abrasion properties of PEN- and PET-based magnehc tapes. The PEN tapes have better dimensional stability, elastic moduli and coating thickness. They also have higher storage moduli... 

There are several interesting applications reported in the literature, such as insulated wire and cable, UV cross-linking of drawn fibers, and tapes from ultra-high-molecular-weight polyethylene. Semi-interpenetrating networks (IPNs) from acrylates and polyurethanes are suitable as UV curable adhesives with high elasticity, good impact resistance, and excellent adhesion to a variety of substrates. ... 

Disposables are also considered to be an environmental threat. Only some of the materials used in the diapers are biodegradable (the wood pulp and SAP). The polyethylene and polyester sheets are not biodegradable neither is the elastic used for better fit, nor the polypropylene used for the tape that is employed as a fastener. Disposable diapers account for up to 2 percent of the total volume of landfills in the United States. The lifetime of the diaper in the landfill depends on several environmental factors soil condition, groundwater flow, and the presence of other materials in the soil. see also Matertals Science Polymers, Synthetic. 

Assuming that adhesion comes from only a van der Waals attraction G = - Afam/(12jrZ2)], neglecting any balancing forces or any elastic properties of the tape, show that when tape-surface separation l = 0.5 nm (5 A), W= z = 0.01 m (1 cm), and G = 0.2 mj/m2 (0.2 erg/cm2), the peeling force is a tiny constant 0.002 mN = 0.2 dyn whereas the maximum perpendicular-pull-off force on this same square patch is an effortful 80 N = 8 x 106 dyn. 

Bostik, Inc., formerly Bostik Findley, Inc., is a leading global producer of adhesives and sealants. The firm operates in five segments construction and distribution performance adhesives nonwovens/tape and label global transportation and flexible laminating. The construction and distribution division manufactures flooring installation adhesives for tile, stone, hardwood, carpet and vinyl caulks, elastic adhesives, aerosol adhesives, fire-retardant adhesives, epoxies,... 

Small-strain oscillatory shear experiments show that the /1-sheet tapes form elastic gels over the whole frequency window (10 -10 rads ), implying that the relaxation time of the network is very long [48].
