A ABS (Acrylonitrile-Butadiene-Styrene): A subdivision of thermoplastic made from three monomers, butadiene, acrylonitrile, and styrene, producing a plastic that is strong, long-wearing, and stain and chemical resistant. ACRYLIC: a hard thermoplastic made from acrylic acid or acrylic acid derivatives. Best known as a glass substitute under trade names such as Lucite and Plexiglas. ACRYLIC RESINS: a class of thermoplastic resins produced by polymerization of acrylic acid derivatives and raw natural resources like natural gas and petroleum. ADA SIGN: all signage in compliance with the Americans with Disabilities Act codes, including specific colors, display options, and raised text and Braille writing.
BOND: to attach by means of adhesive. All Slenderline sign products involve bonding to create multi-layered boards allowing for inserts. BUILDING DIRECTORY: a sign displaying a list of office numbers, names, and other information to aid in locating destinations within that building. BUSINESS SIGNS: any signs designed to communicate with an emphasis on business-related language. Most of the signs featured on the Acrylic Sign World website are designed for a variety of functions suitable to office buildings and small businesses alike. COMPOUND: a combination of ingredients before being processed or made into a finished product. COPOLYMER: two or more chemically different monomers combined with each other through the process of inter-polymerization, uniting their properties. DEGRADATION: the degenerative change in the physical properties of a plastic due to wear, time, weather, or other potentially destructive conditions. DENSITY: weight per unit volume of a given substance. ELASTIC LIMIT: the amount of a load which warps a plastic beyond it's ability to return to it's original form after the load is removed. ELASTICITY: that property of plastics materials by virtue of which they tend to recover their original size and shape after deformation. EXTRUSION : the process of molding plastics into sheets, rods, or other shapes by forcing the polymers through a die forming it into the desired shape. FILLER : an inert powder or fiber material added to a plastic to modify strength, durability, working properties, or other qualities. FUSE: use of heat or solvents to join two plastic parts. The process softens or liquefies the material, and produces a stronger connection than adhesive bonding. INJECTION MOLDING: method of forming plastic to the desired shape by forcing heat-softened plastic into a relatively cool cavity where it rapidly solidifies. Most mass-produced plastic products are made using injection molding. LAMINATE: to build up to a desired thickness by bonding layers of material using pressure and heat. Any material formed by this process is known as a laminate.
MONOMER : a simple compound with a low molecular weight. Monomers are combined to form polymers, producing a higher molecular weight material. See polymerization. PETG: (polyethylene terephthalate glyco) polyester chemically modified to produce a copolyester with greater strength and UV-resistance. PHENOLIC (phenol - formaldehyde) a filler- reinforced polymer with superior weatherability and UV-resistance. Often used to make ADA signs mounted outdoors. PLASTIC: polymers developed from oil refining and coal distillation by-products. Plastic is stable and retain its shape until altered using chemicals or heat and pressure. PLASTICIZER : a filler used to produce a more flexible property in a polymer. POLYCARBONATE: a hard thermoplastic highly resistant to softening and impact. Polycarbonate is used to make anything from bulletproof glass to directory inserts. POLYMER : a compound formed by chemically merging two or more monomers of the same type. POLYMERIZATION : the chemical process of linking monomers to form new compounds called polymers. Styrene polymerized into polystyrene is an example of this process. POLYSTYRENE: a plastic produced using a resin made by the polymerization of styrene as the only monomer. PVC: (polyvinyl chloride) a tough thermoplastic resistant to water, acids and abrasions. REINFORCED PLASTIC: a plastic processed with more durable fillers to increase its strength. RESIN: a shapeless polymeric substance which can be combined to form plastics with various properties. THERMOFORMING : The shaping of heat softened thermoplastic sheet through heat and/or vacuum. THERMOPLASTIC: widely used materials, such as acrylic, ABS, polycarbonate and PVC, which can be softened and melted repeatedly, and hardens when cooled. THERMOSET: a plastic resin cured by heat causing a chemical reaction rendering the substance unable to be softened again using heat. Silicone, epoxy, and urethane are examples of thermoset plastics. THERMOSETTING: A method of thermoforming in which plastics can be melted only once, and hardens as further heat is applied. VULCANIZATION : The process which makes rubber molds flexible and elastic.
