What is Acrylic? Definition, History and Usage Areas
Acrylic is a versatile, durable, and transparent material. It is the general name for polymers of acrylic acids processed with light, heat, or metals. This material, also known as plexi, plexiglass, or mica in daily life, is a thermoplastic substance used in various fields. In this guide you will find the definition and history of acrylic, its technical properties, production types, a comparison with glass, its main usage areas, its advantages and disadvantages, and the correct maintenance methods.
The term acrylic actually covers a wide family of products and has different forms:
- Plexi (PMMA): Polymethyl methacrylate-based thermoplastic material
- Acrylic fabric: A type of synthetic fabric
- Acrylic paint: A water-based paint type
- Acrylic resin: Solid material used as a surface material
History
The first acrylic acid was discovered in 1843, and in 1865, methacrylic acid was formulated from acrylic acid. In 1933, German chemist Otto Röhm developed the product patented as "Plexiglas," pioneering widespread commercial applications. It began to be used in critical areas such as aircraft windows and submarine periscopes during World War II.
Properties of Acrylic
The technical properties below explain why acrylic is often preferred over glass and other transparent materials:
- Transparency: It has higher light transmittance than glass. It transmits light at a rate of 92% compared to normal glass, making it ideal for optical applications.
- Durability: It is 6 times more resistant to impacts than normal glass. When broken, it does not form sharp-edged pieces, which provides an advantage in terms of safety.
- Lightness: It has about half the weight of glass of the same thickness, which provides ease of transportation and installation.
- Thermal properties: It can take shape at approximately 150°C and maintains its shape when cooled. Maximum temperature resistance is 80°C. Combustion temperature is 400°C and it can ignite with flame at 250°C.
- Variety: It can be produced as colorless, transparent colored, colored, and opaque. It is also available in fluorescent colors.
- UV resistance: It is resistant to atmospheric conditions and UV rays, therefore it is long-lasting in outdoor applications.
Types of Acrylic (Plexi)
Depending on the production method, there are two main types of plexi:
- Cast plexi: It is produced by pouring into special molds. It can be produced in various sizes from 2 mm to 40 mm thickness. It is extremely suitable for processing as it has no internal material tension.
- Extruded plexi: It is produced by extruding liquid material as a sheet. It can be produced up to a maximum thickness of 20 mm. It is a more economical option.
Comparison of acrylic (plexi) and glass
| Property | Plexi (acrylic glass) | Normal glass |
|---|---|---|
| Light transmittance | 92% (higher) | 88% |
| Impact resistance | 6 times more durable | Fragile |
| Weight | Half as heavy as glass | Heavier |
| Breaking property | Non-sharp pieces | Sharp glass fragments |
| Processability | Easily shapeable | Requires special equipment |
| Scratch resistance | Softer (copper hardness) | Harder |
