Acrilan

== Description ==
[Solutia, Inc. (formerly Monsanto)] A registered trademark for an acrylonitrile-vinyl acetate copolymer fiber that is commonly used in textiles. Acrilan® was first produced in 1949 by Chemstrand Corp. After slight changes in the formulation and manufacturing procedures, Acrilan® was first commercially manufactured in 1954. It is an acrylic fiber copolymerized with less than 15% vinyl acetate groups. Acrilans are noted for softness, strength and wrinkle-resistant properties. Acrilan® is used for clothing, carpets, drapes, upholstery and laminates. Its wear resistance is better than that of wool, but generally greatly inferior to that of nylon or Terylene. It is unaffected by mildew, molds, moth and carpet beetle larvae.
In 2003, Solutia went into bankruptcy and reorganized. The Acrilan production plant closed in 2020.

Acrylic adhesive

== Description ==
Acrylic resins are used for many types of soft, but durable adhesives. As aqueous emulsions, acrylics form a viscous, white latex that polymerizes into a crystal clear solid. It is waterproof, tough and durable. Acrylic resins are also used as pressure-sensitive adhesives for plastic, paper, fabric, tapes and labels. When dissolved in a small amount of solvent, acrylic resins produce a clear, strong, fast-setting adhesive used on a range of materials, including ceramics, fabrics, plastics, metal, paper, wood, and glass.

Acrylic fiber

== Description ==
A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of acrylonitrile units (Federal Trade Commission definition). Acrylic fibers were first commercially manufactured in 1950 by DuPont as the product Orlon®. The acrylic resin is dissolved in a solvent, then extruded through spinnerets to produce long, continuous filaments. The smooth, thermoplastic fibers are resistant to wrinkles, chemicals, UV light, weathering, insects, mildew, and moisture. They produce fabrics that are non-allergenic, lightweight, soft, durable and fast drying. They are, however, susceptible to heat and will melt or burn. Acrylic fibers are used for carpets, blankets, drapes, outdoor products (awnings, geotextiles, etc) and apparel such as sweaters, coats, linings, hosiery, dresses, and shirts.

Acrylic sheet

== Description ==
A transparent sheet or film made of acrylic resins. Originally introduced as 'organic glass' in 1931, the thermoplastic acrylic sheets are prepared by cast polymerization or extrusion. Some common brand names are Plexiglas®, Perspex®, and Lucite®. Acrylic sheets are lightweight, tough, and colorless with excellent clarity and outdoor weather resistance. Compared to glass, acrylic is lighter and shatter-resistant, but more susceptible to scratching and transmission of UV. Acrylic has the unique ability to carry light around corners. Acrylic sheets are used for safety glass, aircraft canopies, windows, skylights, signs, instrument dials, tail light lenses, lighting fixtures, optical lenses, storage and display cases, bulletproof glass. Other types of clear plastic glazing include polycarbonate sheets (e.g. Lexan®).

Acrylonitrile butadiene styrene

== Description ==
A family of thermoplastic polymers prepared by either grafting styrene and acrylonitrile onto an elastomeric polybutadiene backbone or by mechanically blending rubber copolymer matrices of styrene-acrylonitrile with butadiene-acrylonitrile. Varying the ratios of the three monomers produces a wide range of properties. Acrylonitrile provides resistance to chemicals, high temperatures, and creep deformation while butadiene adds toughness and styrene gives high modulus of elasticity and low cost. The standard grade of ABS resin is strong, resilient, and difficult to break. The polymer can be injection molded or extruded into numerous shapes. ABS resin is used for appliances, automobile parts and fittings, telephones, radios, televisions, pipes and conduits, luggage, boats, toys, and bottles.

Acrysol

== Description ==
[Rohm & Haas] A registered trademark for a series of acrylic dispersions. An early reference lists Acrysol® resins as solutions of Acryloid® resins (Brady 1971). However, the Acrysol® resins sold currently are milky white emulsions polyacrylic acid mixed with acrylic copolymers or sodium polyacrylate. Neutralization of the emulsion with any basic compound causes it to clarify and thicken. Acrysol® resins are used as thickeners in acrylic paints, coatings, and adhesives as well as fabric sizes. They are also used as emulsifying agents. By themselves, Acrysol® resins dry to a transparent, colorless film that can be slightly brittle and hygroscopic.

Actinium

== Description ==
A naturally occurring, radioactive element found in uranium ores. Actinium has a half-life of 21.77 years. Metallic actinium is silvery white and produces a faint blue glow which is visible in the dark. Actinium was first isolated and named in 1899 by André Debierne; in 1902, it was independently discovered by Friedrich Giesel and named emanium. The two elements were reconciled as one in 1904. Actinium is a highly reactive material with a strong basic character that produces water-insoluble salts with most anions. It is very difficult to extract and separate from uranium ores and has limited commercial applications.
