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:
“If I don’t write to empty my mind, I go mad. As to that regular, uninterrupted love of writing ... I do not understand it. I feel it as a torture, which I must get rid of, but never as a pleasure. On the contrary, I think composition a great pain.”
—George Gordon Noel Byron (1788–1824)
“Boswell, when he speaks of his Life of Johnson, calls it my magnum opus, but it may more properly be called his opera, for it is truly a composition founded on a true story, in which there is a hero with a number of subordinate characters, and an alternate succession of recitative and airs of various tone and effect, all however in delightful animation.”
—James Boswell (1740–1795)
“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)
