Composition
Vinyl straps are normally composed of virgin or non-virgin vinyl.
Virgin vinyl is new vinyl manufactured and extruded with the original vinyl chemical solution being used. The chemicals and color pigments are pristine, and the entire production process is new and sterile from the beginning. This form of vinyl strapping has great recovery when stretched, the colors are sharp and clear, and its protection from ultra violet rays is very good. Stain-resistant chemicals are built into the product, increasing its lifespan and protecting its appearance.
Non-virgin vinyl is only used to make black or grey extruded products. Vinyl that has been recycled from old straps that have not sold because a color was discontinued or from used straps that have been removed from old furniture are ground up into small bits and melted. Then, black colorant is added and the solution is reformed into screen spline, rub rail and other non furniture straps products. This process eliminates the features of original virgin vinyl.

Famous quotes containing the word composition:
“Every thing in his composition was little; and he had all the weaknesses of a little mind, without any of the virtues, or even the vices, of a great one.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Since body and soul are radically different from one another and belong to different worlds, the destruction of the body cannot mean the destruction of the soul, any more than a musical composition can be destroyed when the instrument is destroyed.”
—Oscar Cullman. Immortality of the Soul or Resurrection of the Dead? The Witness of the New Testament, ch. 1, Epworth Press (1958)
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
