Novel shrink film needs no heat. (Keeping up with Extrusion).This film shrinks in contact with water, not heat. The patented dual-material film combines an elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. with a water-dispersible polymer. It is stretched mono- or biaxially to as much as twice its original dimensions. The stiffer water-dispersible polymer holds the stretch while the film remains dry. But when wet, the water-dispersible polymer softens and allows the elastomer to shrink back Verb 1. shrink back - pull away from a source of disgust or fear retract cringe, flinch, funk, quail, recoil, wince, shrink, squinch - draw back, as with fear or pain; "she flinched when they showed the slaughtering of the calf" to its original dimensions. Kimberly-Clark Corp. in Roswell, Ga., developed the concept for disposable-diaper backing made from mono-layer blends of the two materials (covered by U.S. Patent #5,641,562). Kimberly-Clark is now looking to license it for other applications such as moisture indicators, sensors, seals, gaskets, and form-fitting packaging like horticultural hor·ti·cul·ture n. 1.

Elastomers could be Kraton or other styrenic block copolymers and EVA Eva to marry winner of singing contest. [Ger. Opera: Wagner, Meistersinger, Westerman, 225–228] See : Prize 1. Eva - A toy ALGOL-like language used in "Formal Specification of Programming Languages: A Panoramic Primer", F.G. or other polyolefins. Water-dispersible polymers could be polyethylene oxide, polyvinyl alcohol polyvinyl alcohol, n a complex alcohol that is soluble in water and is used as an emulsifier and adhe-sive. , polyacrylic acid, or starch. Water dispersibility can also be triggered by pH level. Tel: (678) 532-6360, www.yet2.com |
