Acrylic and plastic are often confused as the same thing, but while acrylic is a type of plastic, not all plastics are acrylic. Acrylic, also known as polyacrylate, is a thermoplastic that is petroleum-based and derived from natural glass. It is a clear plastic that is sold under various brand names, including Plexiglas, Perspex, Lucite, and Acrylite. Acrylic is known for its strength, stiffness, and optical clarity, making it a popular choice for various applications such as accessories, displays, windows, and more. On the other hand, the term plastic refers to a broad family of synthetic or semi-synthetic materials, which includes a wide range of different types of plastics such as polystyrene and polycarbonate.

What You'll Learn
Acrylic is a type of plastic
Acrylic is sold under numerous brand names, including Plexiglas, Perspex, Lucite, Acrylite, OPTIX, and KSH. It can be injection-moulded or hand-crafted. Injection-moulded acrylic is made by injecting PMMA into a mould, resulting in a strong, clear plastic that costs less than hand-crafted acrylic. Hand-crafted acrylic is made by bonding all joints by hand using solvent agents, resulting in a crystal-clear construction that is extremely strong.
Acrylic has a similar optical clarity to glass but has better impact resistance and is lighter in weight. It is also less likely to scratch compared to glass and other plastics such as polycarbonate. Acrylic ages without pronounced discolouration, such as yellowing, compared to other plastics.
Acrylic plastic comes in many different grades that enhance its performance for specific applications and purposes. Grades include general-purpose clear acrylic, abrasion-resistant, impact modified, light diffusing, bullet-resistant, sign-grade, non-glare, antimicrobial, and digital print. Acrylic plastic is available in various colours and ranges of opacity, including translucent, transparent, mirrored, and opaque.

Acrylic is a thermoplastic
Acrylic is a type of plastic. It is a synthetic resin produced from the polymerisation of methyl methacrylate. Poly(methyl methacrylate), also known as acrylic, is a transparent thermoplastic. It is often sold in sheet form under brands such as Altuglas, Plexiglass, Perspex, and Lucite.
Acrylic is available in pellet, small granules, and sheet form, which can be formed through all thermoplastic methods. It is suitable for processing by injection moulding, casting, extrusion, and thermoforming. Acrylic is a thermoplastic, which means it responds to heat by becoming liquid at its melting point. This is around 160 degrees Celsius for acrylic. This means that, unlike thermoset plastics, they can be heated, cooled, and reheated without significant damage.
Acrylic is a tough, highly transparent material that can be coloured, moulded, cut, drilled, and formed. It exhibits glass-like qualities such as brilliance, clarity, and transparency. The plastic has 10 times the impact resistance of glass and is half the weight. Acrylic is commonly used in architecture and construction, lighting, design, automotives, electronics, and medical supplies.

Acrylic is stronger than polystyrene
Acrylic is a type of plastic. More specifically, it is a thermoplastic, which means it can be melted and moulded into any shape and then reheated and reshaped without signs of degradation. Acrylic is a clear plastic, but it is just one of many different clear plastics.
Acrylic, on the other hand, is a petroleum-based thermoplastic made from methyl methacrylate (MMA) and/or polymethyl methacrylate (PMMA). It is sold under numerous brand names, including Plexiglas, Perspex, Lucite, Acrylite, OPTIX, and others. Acrylic is less likely to scratch compared to other plastics such as polycarbonate and polystyrene. Any scuffs on its appearance may be polished out. Acrylic is also known to age without pronounced discolouration, such as yellowing, compared to other plastics.
Acrylic has outstanding stiffness and strength and many times the impact resistance of glass. It is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It exhibits glass-like qualities at half the weight of glass. Acrylic is also more flexible than polystyrene. It can be machined in a lathe, whereas polystyrene tends to disintegrate.

Acrylic is lighter than glass
Acrylic is a type of plastic, specifically a thermoplastic, that is derived from natural glass. It is made from methyl methacrylate (MMA) and/or poly methyl methacrylate (PMMA). Acrylic is sold under various brand names, including Plexiglas, Perspex, Lucite, Acrylite, OPTIX, and KSH.
Acrylic is a popular material used in manufacturing and design. It is known for its durability, strength, stiffness, and optical clarity. Acrylic exhibits glass-like qualities, such as clarity, brilliance, and transparency, but it is much lighter than glass. In fact, acrylic weighs approximately 50% less than glass. This lightweight property of acrylic makes it easier to install and more environmentally efficient.
Acrylic is also more malleable than glass, allowing it to be formed into various shapes while maintaining excellent optical properties. Its impact resistance is significantly higher than that of glass, making it 10 times more shatter-resistant. Acrylic can transmit up to 92% of visible light, compared to the 80-90% typically transmitted by glass. Additionally, acrylic provides 99% UV blocking, while standard-grade glass blocks almost none.
The lightweight, durable, and impact-resistant nature of acrylic makes it ideal for a variety of applications. It is commonly used in signage, retail display cases, window glazing, aquarium tanks, protective barriers, face shields, and picture framing. Acrylic's ease of fabrication and ability to be moulded into different shapes also make it suitable for decorative panels, furniture, and lighting fixtures.
Overall, the superior properties of acrylic over glass, particularly its lighter weight, make it a preferred choice in many commercial, industrial, and residential applications.

Acrylic is easy to fabricate
Acrylic is a type of plastic. It is a thermoplastic, meaning it can be melted and moulded into any shape and then reheated and reshaped without degradation. This makes it easy to fabricate. Acrylic is also sold under brand names such as Plexiglas, Perspex, Lucite, Acrylite, OPTIX, and KSH.
Acrylic is a mixture of monomer and polymer. It is a clear plastic, but it is just one of many different clear plastics. Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. It exhibits glass-like qualities but is only half the weight of glass and has better impact resistance. Acrylic is also available in a variety of colours, including black, white, red, green, and yellow, and a range of opacities, including translucent, transparent, mirrored, and opaque.
Acrylic fabrication results in a strong, versatile material. It is ideal for many applications, including outdoor signs, display cases, custom furniture, point-of-purchase displays, picture frames, signage, windows, and more. Acrylic is also used in the automotive industry for interiors of automobiles and watercraft, and in the construction of buildings.
Acrylic sheets can be formed via three methods: extruded, cast, or continuous cast. Once the acrylic sheet is formed, there are several different fabrication methods that can be used to customize and form it into specific shapes, sizes, and objects. Acrylic can be cut to desired sizes or flat shapes using methods such as saw cut or routing, and then edge finishing and polishing can be used to provide a clean edge. CNC routing can be used to cut curves, corners, and complete shapes. Bending and shaping acrylic can be done through processes like heat bending, which involves applying high temperatures to the material so that it can be manipulated into specific angles easily.
