acrylic resin
Noun: 1. A synthetic polymer material: A type of clear, hard plastic made by polymerizing derivatives of acrylic acid. It is known for its transparency, durability, and resistance to weathering. 2. A versatile thermoplastic: A material that becomes soft and moldable when heated and hardens upon cooling, allowing it to be cast, extruded, or molded into various forms.
Acrylic resin is used as a material in manufacturing and art. It is often discussed in contexts involving production, fabrication, and material science. * As a subject: "The acrylic resin was heated to 160°C before molding." * As an object: "The artist prefers to use acrylic resin for its clarity." * With a preposition: "The parts are bonded with a layer of acrylic resin."
- "The museum display case is made from a high-grade acrylic resin for optimal clarity and protection."
- "Acrylic resin is a common base for durable, water-based house paints."
- "Dentists use a special acrylic resin to create temporary crowns and dentures."
- In a technical/scientific context: Refers to the specific chemical family of polymers derived from esters of acrylic acid or methacrylic acid (e.g., poly(methyl methacrylate) or PMMA).
- Example: "The study compared the tensile strength of different acrylic resin formulations."
- Acrylic (noun): A common shortened form, especially when referring to the solid plastic material (e.g., acrylic sheet) or acrylic paint.
- Example: "The window is made of acrylic."
- Poly(methyl methacrylate) (PMMA) (noun): The full chemical name for the most common type of acrylic resin, often known by trade names like Plexiglas or Lucite.
- Acrylic fiber (noun): A synthetic fiber made from a polymer (polyacrylonitrile) related to, but distinct from, the thermoplastic acrylic resins used for sheets and coatings.
- Poly(methyl methacrylate): The specific technical name.
- Acrylic plastic: A descriptive synonym emphasizing its material category.
- PMMA: An initialism for the technical name.
The core meaning refers to the synthetic polymer material itself. Its key characteristics—transparency, moldability, and adhesive/coating properties—define its primary applications. It is distinct from "acrylic paint," which uses an acrylic resin emulsion as a binder but is a liquid mixture, not the solid resin itself.
-
a glassy thermoplastic; can be cast and molded or used in coatings and adhesives
