What You'll Learn
Acrylic is a thermoplastic
Acrylic is a synthetic resin, typically derived from acrylic acid, methacrylic acid, and acrylate monomers such as butyl acrylate and methyl methacrylate. It is a clear, colourless polymer, available in pellet, small granules, and sheet form. Acrylic is also known as poly(methyl methacrylate) (PMMA), and is a tough, highly transparent material that can be coloured, moulded, cut, drilled, and formed. It is commonly used in sheet form as a lightweight, shatter-resistant alternative to glass. Acrylic sheets are often used to create products such as mirrors and plexiglass.
Acrylic is also used in a wide range of applications, including architecture, construction, lighting, design, automotives, electronics, and medical supplies. It is easy to machine, fabricate, and thermoform, and it bonds well with adhesives and solvents. Acrylic can be assembled using adhesives, double-sided tapes, or mechanical fasteners. It can also be painted and screen-printed using paints produced specifically for acrylic or vinyl.
Acrylic is stronger than other transparent plastics, and has 10 times the impact resistance of glass, with half the weight. It is also highly resistant to harsh disinfectants and cleaners. Acrylic is available in many different grades, which 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 is shatter-resistant
Acrylic is a type of plastic that is shatter-resistant. It is a transparent thermoplastic that is commonly used as a lightweight and shatter-resistant alternative to glass. Acrylic is often used in sheet form to create products such as mirrors, plexiglass, bakery bins, sunglasses, and display risers. It is also available in rod and tube form, which are used for point-of-purchase display applications.
Acrylic is a strong and durable material that exhibits high tensile strength compared to other transparent plastics. It is also impact-resistant, with some sources claiming it is up to seventeen times more impact-resistant than glass. This makes it a great choice for applications where shatter resistance is important, such as in security or automotive industries.
The shatter resistance of acrylic can be further enhanced through specialty coatings. These coatings can also provide additional benefits such as scratch resistance, UV protection, and non-glare properties. Acrylic is available in a variety of grades, including impact-modified, which likely contributes to its shatter-resistant properties.
Acrylic is also easy to machine, fabricate, and thermoform, making it a versatile material for various applications. It can be assembled using adhesives, double-sided tapes, or mechanical fasteners. Additionally, acrylic can be painted and screen-printed, allowing for easy decoration and customization.
Overall, acrylic's shatter resistance, combined with its strength, durability, and ease of use, makes it a popular choice for a wide range of applications, particularly where shatter resistance and impact strength are important.

Acrylic is used in medical applications
Acrylic is a transparent thermoplastic that is widely used in medical applications. It is a popular alternative to glass due to its lightweight, shatter-resistant properties. Acrylic is also known for its high tensile strength, making it a durable option for medical devices and equipment.
One of the key advantages of acrylic in medical applications is its inert nature. Acrylic does not react with reagents used in testing, making it ideal for diagnostic equipment. Acrylic offers 92% light transmittance, with exceptional clarity at lower wavelengths of 270 to 350 nm. This property makes acrylic the preferred choice for disposable cuvettes, which are used to contain blood and other fluids for UV light analysis.
Acrylic is also biocompatible, meaning it can be safely used in direct contact with human tissue. This characteristic has led to its use in intraocular prostheses and various medical devices such as syringes, luers, blood filters, and surgical instruments. Acrylic is easy to process and assemble, and its impact-modified grades provide increased resistance to breaking and cracking.
In addition, acrylic exhibits good chemical and scratch resistance, enhancing its durability in medical settings. Acrylic can be easily cleaned with mild soap or detergent and lukewarm water, maintaining a sterile environment. Acrylic's versatility extends to its availability in various grades, colours, and opacity levels, allowing for customization based on specific medical needs.
Overall, acrylic's unique combination of optical clarity, strength, biocompatibility, and ease of processing makes it a valuable material in medical applications, contributing to advancements in healthcare technology.

Acrylic is easy to machine
Acrylic is a transparent thermoplastic with excellent strength and optical clarity. It is a popular alternative to glass as it is shatter-resistant, lightweight, and tougher. It is also used in place of glass in applications where its impact resistance is required, as it is 17 times more impact-resistant than glass. Acrylic is also easy to machine and fabricate, and it bonds well with adhesives and solvents.
Acrylic is available in a variety of colours and opacity levels, including translucent, transparent, mirrored, and opaque. It can be purchased in sheets, rods, and tubes, and can be cut to size. Acrylic is also easy to assemble, using adhesives, double-sided tapes, or mechanical fasteners. It can also be painted and screen-printed.
However, it is important to note that acrylic is not very heat-resistant, and it has a low melting point. This means that when machining acrylic, it is necessary to use a sharp cutting tool with a slow feed rate to obtain a smooth surface finish. Cast acrylic is preferable over extruded acrylic for machining as it is more rigid and less prone to stress cracking.
When machining acrylic, it is also important to consider the finish. Acrylic will become frosted during the machining process, so it will require polishing to restore clarity. This can be done through vapour polishing, mop polishing, or heat annealing.
Overall, while acrylic is easy to machine, fabricate, and assemble, there are some important considerations to keep in mind to ensure a successful outcome.
