Acrylic and plastic are both in the polymer family, but there are differences between the two materials. Acrylic is a type of thermoplastic that is petroleum-based and derived from natural glass, while plastic is a generic term for a large family of synthetic or semi-synthetic materials. Acrylic is known to be more durable than plastic, with greater impact resistance, but it is also more prone to cracking. Acrylic is also more scratch-resistant and fade-resistant than plastic. Acrylic is commonly used in applications such as plexiglass windows, automotive screens, computers, and aquariums, while plastic has a wide range of uses.

What You'll Learn
Acrylic is a type of plastic
Acrylic plastic is a versatile material with a wide range of applications. It is used in skylights, signs, point-of-purchase displays, windows, picture frames, furniture, aquariums, and DIY projects. Acrylic is also used in optical applications such as plexiglass windows, automotive screens, computers, eyeglasses, and tanks.
Acrylic plastic has several advantages over other types of plastic. It is light, easy to fabricate, transparent, and more fade-resistant than other plastics. Acrylic has superior weathering properties and is highly durable, with greater impact resistance than glass. It is also easy to maintain and clean, although it requires gentle handling to prevent scratches.
Acrylic plastic can be machined, fabricated, thermoformed, and it bonds well with adhesives and solvents. It can be assembled using adhesives, double-sided tapes, or mechanical fasteners. Acrylic can also be painted and screen-printed using paints designed specifically for acrylic or vinyl.
When heated, acrylic becomes malleable and can be molded into various shapes. As it cools, it holds its formed shape and can be machined, drilled, or sawed. Acrylic is less expensive than some other plastics, such as polycarbonate, but it is more vulnerable to cracks.

Acrylic is more durable than some plastics
Acrylic is a type of plastic that is more durable than some other plastics. It is a synthetic polymer and one of the oldest synthetic materials available. Acrylic is a mixture of monomer and polymer, and it is a type of thermoplastic that is petroleum-based and derived from natural glass. It is also known as polyacrylate.
Acrylic plastic has many advantages over other plastics. It is lightweight, easy to fabricate, transparent, and versatile. It can be heated and moulded into various shapes, and it holds its formed shape, allowing it to be machined, drilled, or sawed like wood. Acrylic is also more fade-resistant than other plastics and has superior weathering properties. It exhibits glass-like qualities of clarity, brilliance, and transparency, but at half the weight of glass. Acrylic is also easier to clean than glass and has a broader temperature range for application use.
In terms of strength, acrylic has outstanding impact resistance—up to 17 times more than glass. It takes a lot of force to shatter acrylic, making it a durable alternative to glass. Acrylic is also scratch-resistant and does not decay over time. However, it is important to note that acrylic can be scratched with very sharp objects and is vulnerable to cracks.
When compared to polycarbonate, another type of plastic, acrylic is less expensive and easier to crack. Polycarbonate is stronger, more flexible, and has higher impact resistance than acrylic, making it ideal for highly demanding applications like bullet-resistant windows. Polycarbonate is also easier to scratch than acrylic.

Acrylic is easy to clean
To clean acrylic, it is recommended to use a commercial plastic cleaner or a mild soap with water to remove dirt and debris. You can also use a 50/50 mix of isopropyl alcohol and water. Use a microfiber cloth to gently blot the surface clean. Microfiber cloths are soft and non-abrasive, so they are perfect for cleaning acrylic. They are also good at absorbing moisture and are lint-free. Polish Mate Wipes are another good option, as they are disposable, so there is no chance of dirt buildup on the cloth.
When cleaning, work on small areas at a time to prevent scratches. Always use a separate cloth for cleaning acrylic to avoid transferring dirt, grit, or chemical residues from other surfaces.
Acrylic is sensitive to certain cleaners, so it is important to avoid using harsh solvents or ammonia-based products, such as window cleaner or Windex. These will damage the surface of the acrylic and cause it to appear cloudy. Do not use any scouring compounds or chemical cleaners, even if they are environmentally friendly.
For tough grease, oil, or tar residue, use commercial-grade hexane or kerosene, and always wipe acrylic clean with fresh water and blot it dry to prevent water spotting.
Acrylic is also prone to static electricity buildup, which can attract dust and dirt. This can be reduced by using an anti-static cleaner with a soft cloth.

Acrylic is more expensive than Plexiglas
Acrylic, also known as Plexiglas, is a versatile plastic material with various opacities and colours. It is one of the world's oldest synthetic materials, having been first produced in 1928 and introduced to the public in 1933. Acrylic is a mixture of monomer and polymer, and it is a type of thermoplastic that is petroleum-based and derived from natural glass.
Plexiglas is created through the cell casting technique, which involves a strenuous amount of time, effort, resources, and cost. This process makes Plexiglas more durable than acrylic, but it also contributes to its higher price. Acrylic, on the other hand, is manufactured using the less costly extrusion process, making it more affordable.
The cost difference between acrylic and Plexiglas is also influenced by their respective strengths. Acrylic is stronger than polycarbonate, a type of plastic commonly compared to acrylic due to their similar appearance. Polycarbonate sheets can cost around 35% more than acrylic, making acrylic a more cost-effective option for those seeking a strong and durable plastic.
Additionally, acrylic's versatility in terms of shape further enhances its value. Acrylic can be formed into almost any shape, whereas glass has limitations in this regard. Acrylic's ability to withstand more pressure also makes it easier and safer to install in applications such as windows or windshields.
While acrylic is generally more expensive than other types of plastic, it offers advantages such as higher strength, durability, and versatility in shape and design. These factors contribute to its higher cost compared to other plastics, including Plexiglas, but also make it a preferred choice for specific applications where its unique properties are required.

Acrylic is more breakable than polycarbonate
Acrylic and polycarbonate are both types of plastic. They are similar in appearance and are the most frequently used see-through plastic materials on the market. However, they have distinct differences in terms of their characteristics and applications.
Acrylic, also known as Plexiglas, is a clear plastic that is widely used in manufacturing and design. It is a thermoplastic that is petroleum-based and derived from natural glass. Acrylic is known for its high gloss finish and transparency, making it ideal for applications such as display cases, plexiglass windows, automotive screens, computers, eyeglasses, and aquariums. One of the advantages of acrylic is that it can be heated, moulded into various shapes, and reheated while retaining its quality appearance. It is also lighter and easier to fabricate than polycarbonate. However, one of its drawbacks is that it is more prone to cracking and breaking compared to polycarbonate.
On the other hand, polycarbonate is a stronger and more durable material. It has 250 times the impact resistance of standard glass, while acrylic has only about 17 times the impact resistance. This makes polycarbonate ideal for highly demanding applications such as bullet-resistant windows. Polycarbonate is also easier to scratch than acrylic. In terms of cost, polycarbonate sheets are generally more expensive than acrylic, averaging about 35% more.
While both materials have their advantages and disadvantages, the choice between acrylic and polycarbonate depends on the specific requirements of a project. Acrylic is preferred when a high gloss finish and transparency are desired, while polycarbonate is chosen for applications requiring higher impact resistance and durability.
In summary, while acrylic has its advantages in terms of appearance, workability, and cost, it is indeed more breakable than polycarbonate due to its lower impact resistance.
