Acrylic plastic, also known as plexiglass, is a versatile material with a variety of purposes and benefits. It is a strong, stiff, transparent glass-like material that is easy to machine and has outstanding impact resistance. Acrylic is formed from the polymerisation of methyl methacrylate and was first produced in 1928. It is available in a spectrum of colours and opacities, and can be moulded and coloured to fit specific applications. Acrylic is commonly used in architecture and construction, lighting, design, automotives, electronics, and medical supplies.

What You'll Learn
Strength and stiffness
Acrylic plastic is known for its strength and stiffness. It is a strong, stiff, transparent glass-like material that is easy to machine. Acrylic is a good alternative to glass as it is stronger, lighter, cheaper, and more reliable. It is also 17 times more impact-resistant than glass, making it shatter-resistant.
Acrylic is a versatile plastic material with a variety of purposes and benefits. It can be cut, drilled, coloured, moulded, and formed. It is also available in a spectrum of colours and opacities, including opaque, translucent, and transparent. Acrylic plastic is also known as plexiglass and was first produced in 1928.
Acrylic sheets are easy to fabricate, bond well with adhesives and solvents, and are easy to thermoform. They can be purchased in sheets of various thicknesses and can also be found in the form of rods or tubes. The thickness of an acrylic sheet will positively influence factors like impact resistance. For cast acrylic sheets, thicknesses can range from 0.06 inches to 4 inches.
Acrylic is a tough, highly transparent material. It exhibits glass-like qualities such as brilliance, clarity, and transparency. Acrylic is also lightweight, affordable, and weather-resistant. It can be used in a wide range of applications, including architecture, construction, lighting, design, automotives, electronics, and medical supplies.
Acrylic is a thermoplastic, which means it can be heated, cooled, and reheated without significant damage. It has a melting point of 160 degrees Celsius, at which point it becomes a liquid. Acrylic is also free of bisphenol A (BPA), a hazardous risk to health found in other plastics.

Glass-like qualities
Acrylic plastic is a versatile material with a variety of purposes and benefits. It is a strong, stiff, and transparent glass-like plastic with optical clarity, brilliance, and clarity of transmission. Acrylic plastic is half the weight of glass and has up to 17 times the impact resistance of glass. This makes it a lightweight, shatter-resistant alternative to glass.
Acrylic is also known as plexiglass, and it is often used as an alternative to glass. It is a handmade material, and these handmade acrylic pieces are mainly used for display purposes. Acrylic is a high-quality, strong, and reliable material that is perfect for frames. It is also used in outdoor decks and furniture because it can be made into a lacquer and used as a protective coating.
Acrylic plastic is available in a spectrum of colours and opacities. It can be moulded and coloured to fit specific applications. It is also available in many shapes and sizes, including sheets, rods, and tubes, and styles such as frosted, mirrored, or non-glare. Acrylic sheets can transmit and reflect light better than glass. This is one of the reasons why it is widely used for skylights and roofing panels.
Acrylic plastic has good weathering properties and can withstand long-term exposure to sunlight. It also has low water absorption, good electrical resistivity, and fair tensile strength. Acrylic is a thermoplastic, which means that it can be heated, cooled, and reheated without significant damage. It has a melting point of 160 degrees Celsius, at which point it becomes a liquid.

Impact resistance
Acrylic plastic is well-known for its impact resistance, which is significantly higher than that of glass. In fact, it is estimated to be around 10 to 17 times more impact-resistant than glass, despite weighing only half as much. This makes it an excellent alternative to glass in a variety of applications where impact resistance is a critical factor, such as in the production of lenses, lights, nails, security walls, medical tools, LCD screens, and furniture.
The impact resistance of acrylic plastic sheets can be further enhanced by modifying their thickness. Thicker sheets generally exhibit greater impact resistance compared to thinner ones. For example, cast acrylic sheets, which can range in thickness from 0.06 inches to 4 inches, offer a wider range of impact resistance options.
The outstanding impact resistance of acrylic plastic is attributed to its unique molecular structure. Acrylic, also known by its chemical name polymethyl methacrylate, is derived from the polymerisation of methyl methacrylate. This process results in a clear, colourless polymer with exceptional strength and stiffness.
Additionally, the impact resistance of acrylic plastic can be further modified by adding different substances during the manufacturing process. This allows for the creation of specialised grades of acrylic plastic, such as impact-modified acrylic, which is designed to withstand even higher levels of impact.
The impact resistance of acrylic plastic also contributes to its versatility and durability. Acrylic plastic can be cut, drilled, moulded, and formed into various shapes and sizes, making it suitable for a diverse range of applications, from durable signs and skylights to retail store fixtures, displays, and shelves. Its impact resistance, combined with its lightweight and shatter-resistant nature, makes it a preferred choice over glass in many instances.

Variety of colours and opacities
Acrylic plastic is available in a wide range of colours and opacities. While it is naturally a clear, colourless polymer, it can be customised to fit specific applications. Acrylic is often used as an alternative to glass due to its strength and impact resistance. It is also lightweight, affordable, and shatter-resistant.
Acrylic plastic comes in various opacities, including opaque, translucent, and transparent varieties. Opaque acrylic allows minimal to no light through, blocking out light sources completely. Translucent acrylic allows light through but with significant diffusion or distortion, so the object behind the acrylic is not visible. Transparent acrylic, on the other hand, is clear and allows light through with minimal distortion, much like tinted glass.
The variety of opacities available makes acrylic suitable for a diverse range of applications. For instance, opaque acrylic is often used when a solid colour is desired, such as in signage or displays. Translucent acrylic can be used in lighting applications, allowing light to transmit through without showing the light source. Transparent acrylic is ideal for applications where clarity is important, such as in glazing, aircraft canopies, or lenses.
Acrylic plastic can also be customised in terms of thickness, dimensions, and grade to suit specific requirements. It can be easily fabricated, machined, and thermoformed, making it a versatile and cost-effective material for a wide range of projects. Acrylic is commonly used in architecture, construction, lighting, design, automotives, electronics, and medical supplies.

Easy to fabricate
Acrylic plastic is a highly versatile material that is easy to fabricate. It can be fabricated at home using basic tools such as a scoring knife or a Dremel, or by professionals using more specialised tools.
Acrylic is a thermoplastic, which means it can be heated, cooled, and reheated without significant damage. This makes it ideal for fabrication, as it can be melted and moulded into a wide variety of shapes and forms, including sheets, rods, tubes, and complex shapes. It can also be coloured, cut, drilled, and formed.
Acrylic plastic has excellent bonding properties and can be easily adhered to other materials using adhesives and solvents. It is also suitable for processing by injection moulding, casting, extrusion, and thermoforming.
The ease of fabrication of acrylic plastic makes it a popular choice for a wide range of applications, including art installations, outdoor signs, glazing, aircraft canopies, skylights, auto tail-lights, dials, buttons, lighting applications, knobs, machine covers, lenses, security barriers, LCD screens, and furniture.
