Polypropylene (PP)

Properties: Semi-rigid, translucent, good chemical resistance, tough, good fatigue resistance, integral hinge property and good heat resistance.

Applications: Flexible and rigid packaging, automotive Bumpers, cladding, and exterior trim, consumer products, and industrial uses. PP fibre is used in tape and strapping.

Ethylene Vinyl Acetate (EVA)

Properties: Flexible (rubbery), transparent, good low temperature flexibility (-70'C), good chemical resistance, high friction coefficient.

Applications: Teats, handle grips, flexible tubing, record turntable mats, beer tubing, vacuum, cleaner hosing.

Polymeth-ylpentene (PMP)

Properties: Rigid, tough, lightweight (density 0.83 gm/cm), chemical resistant, additives are required for outdoor use, highly permeable to gases, transparent crystalline material.

Applications: Medical ware, syringes, lamp covers, (good heat resistance), radar applications, encapsulation, microwave food packaging.

The first important plastic, celluloid, was discovered (c.1869) by the American inventor John W. Hyatt and manufactured by him in 1872; it is a mixture of cellulose nitrate, camphor, and alcohol and is thermoplastic. However, plastics did not come into modern industrial use until after the production (1909) of Bakelite by the American chemist L. H. Baekeland. Bakelite, made by the polymerization of phenol and formaldehyde, is thermosetting. New uses for plastics are continually being discovered. Following World War II optical lenses, artificial eyes, and dentures of acrylic plastics, splints that X rays may pierce, nylon fibers, machine gears, fabric coatings, wall surfacing, and plastic lamination were developed. More recently a hydrophilic, or water-attracting, plastic suitable for use in non-irritating contact lenses has been developed. Among the trade names by which many plastic products are widely known are Plexiglas, Lucite, Polaroid, Cellophane, Vinylite, and Koroseal. Plastics reinforced with fiberglass are used for boats, automobile bodies, furniture, and building panels.
