Topics related to "thermoplastics"

thermoplastics
thermoplastics materials that soften or melt when heated and harden when cooled. Thermoplastic polymers consist of long polymer molecules that are not linked to each other. i.e., have no cross-links. They are often supplied as granules and heated to permit fabrication by methods such as molding or ... Read more
polyacrylics
polyacrylics , group of thermoplastics that are transparent and highly decorative (see plastic ). The polyacrylics, or acrylic plastics, are polymers (and copolymers) of derivatives of acrylic acid, H 2 C[symbol]CH-COOH. The best-known acrylic plastic, sold under the trade names Plexiglas and Luc... Read more
acrylic
acrylic artificial fiber made from a special group of vinyl compounds, primarily acrylonitrile. Acrylic fibers are thermoplastic (i.e., soften when heated, reharden upon cooling), have low moisture regain, are low in density, and can be made into bulky fabrics. They wash and dry easily and are dime... Read more
polyvinyl chloride
polyvinyl chloride (PVC), thermoplastic that is a polymer of vinyl chloride. Resins of polyvinyl chloride are hard, but with the addition of plasticizers a flexible, elastic plastic can be made. This plastic has found extensive use as an electrical insulator for wires and cables. Cloth and pape... Read more
polystyrene
polystyrene , widely used plastic ; it is a polymer of styrene. Polystyrene is a colorless, transparent thermoplastic that softens slightly above 100°C (212°F) and becomes a viscous liquid at around 185°C (365°F). It is resistant to acids, alkalies, oils, and alcohols. It is produ... Read more
vinyl plastics
vinyl plastics group of thermoplastics used in molded products, flexible tubing, material for raincoats, and laminated safety glass. Vinyl plastics are polymers and copolymers of vinyl derivatives (i.e., derivatives of ethylene, H 2 C[symbol]CH 2 ), e.g., vinyl chloride (H 2 C=CHCl) and vinyl a... Read more
nylon
nylon synthetic thermoplastic material characterized by strength, elasticity, resistance to abrasion and chemicals, low moisture absorbency, and capacity to be permanently set by heat. After 10 years of research E. I. du Pont de Nemours & Company introduced nylon in 1938 as monofilaments for br... Read more
polyurethanes
polyurethanes , group of plastics that may be either thermosetting or thermoplastic. Polyurethane can be made into both flexible and rigid foams. The flexible foam is often used in furniture and automobile cushions, in mattresses, and for carpet backings. The rigid foam is used for the thermal ins... Read more
plastic
plastic any organic material with the ability to flow into a desired shape when heat and pressure are applied to it and to retain the shape when they are withdrawn. Composition and Types of Plastic A plastic is made up principally of a binder together with plasticizers, fillers, pigments,... Read more
art conservation and restoration
art conservation and restoration the preservation of structurally sound works of art, the halting of processes that lead to the damage of works of art, and the repair of already damaged works of art. Background Works of art are subject to a variety of disfiguring ills, many of them caused... Read more
