1. ACRYLIC DISPLAYS
"Acrylic displays":http://www.akrylix.com/gallery.php?cat=10 can take many forms: "Boxes":http://www.akrylix.com/gallery.php?cat=1, bins, shelves, pedestals, vitrines, drawers, covers, brackets, frames, components, accessories, podiums, partitions, lenses, diffusers, shades, dividers, "literature holders":http://www.akrylix.com/preview.php?photo=125, graphic retainers, models, prototypes, handles, "custom acrylic plastic fabrications":www.akrylix.com , hemispheres, oven formed, decorative, promotional, advertising objects, "acrylic signs":http://www.akrylix.com/preview.php?photo=24, trays, guards, dispensers, panels, windshields, tabletops, cabinets, doors, inserts. All of the above are widely used in "point of purchase displays":http://www.akrylix.com/preview.php?photo=76, trade shows, exhibits, promotional events, hotels, institutions, museums, and the food industry. "Acrylic displays":http://www.akrylix.com/preview.php?photo=29 are fabricated by cutting, drilling, bending, thermoforming, and banding acrylic sheets, rods, or tubing. They can be various forms and sizes. Machines used in *fabricating these displays* are table saw, radial arm saw, band saw, jig saw, jointer, router, drill press, shaper, computer, belt sander, strip heater, vertical mill, horizontal mill, engine lathe, disc sander, fixtures, buffer, hydrogen torch, syringe, solvent, clamps, spring clips, and wax. *Acrylic displays* can be used in almost any environment. They are practical, effective, durable, attractive and in increasing demand. Acrylic is a thermoplastic, which means that it can be heated and reheated in order to bend or mold it. Heating does not change the chemical composition. Other examples of thermoplastics are: acrylo-nitrile (nylon), polyethylene, polypropylene, poly vinyl acetate (PVA), poly vinyl chloride (PVC), polystyrene and ABS, and Teflon. The properties of acrylic that make it attractive are that it is attractive, hard, slippery, soft, rubbery, tough, flexible, insulation from electricity, insulation from heat, light weight, hygienic, non-rusting, easy to shape, easy to color, inexpensive. Plastics can degenerate. Most plastics do not rust or corrode like metals. Plastics are made up of long strings like congealed spaghetti. Solvents seep in between the strings, weakening the structure and making it swell. The material usually softens, and all other properties are also affected. Very strong solvents may even break up and dissolve the strings. Other chemicals, and ultra violet light, cause the chain linking reactions of the plastic to continue and accelerate. The plastic becomes hard and brittle, and small cracks begin to appear at the surface. Once these cracks appear, they continue to grow throughout the material. The cracks usually begin in zones of local stress caused by heating, bending, gluing, or welding. Molded articles may also have internal stress caused by uneven flow of plastic in the molding process. Internal stress can be thought of as neighboring strings within the plastic being stretched by different amounts when the article is made. It is very important for the molds to be properly designed. Plastic sheets may be stored flat, with one sheet upon another on a flat, clean surface, or in a vertical position on edge. The best way to store plastic however, is at a slight angle. The sides should be inclined a few degrees from vertical. When stacking plastic sheets for storage, both sides of the sheets should be brushed, using a soft bristle brush, or soft cloth to remove particles of grit, which may cling to the protective masking paper that sheet stock ships with for protection. This "grit" is attracted by static electrical charge that builds up from the rubbing of the sheets against each other.
