Acrylic is a transparent plastic material that exhibits glass-like qualities at half the weight of glass. It is a strong, stiff, and low-cost plastic with good impact resistance and thermoforming characteristics. Acrylic is also known to bond well with adhesives and solvents. When it comes to low surface energy plastics, they are typically soft and have low melting points, making them easy to process and mold. They are more challenging for adhesives to bond with due to their low surface energy. Acrylic adhesives, such as 3M's 300LSE, have been designed to overcome these challenges and provide strong bonds with low surface energy plastics. So, is acrylic a low-energy plastic?

What You'll Learn
Acrylic plastic is a strong, stiff, transparent glass-like material
Firstly, it is far lighter than glass, with a density of roughly 1.19 g/cm³ compared to the starting density of ordinary glass at 2.5 g/cm³. This makes acrylic much easier to transport, lift and install. Secondly, it has superior optical clarity, with a 92% optical clarity rate compared to 90% for glass. This makes it ideal for applications such as durable signs, skylights, retail store fixtures, displays and shelves.
Acrylic plastic also has better weathering properties than many other transparent materials, and it does not streak or smudge as easily as glass. It is also much easier to clean, requiring only a simple mixture of soap and water, rather than the special anti-streaking cleaning solutions that glass needs. Acrylic is also cheaper to manufacture than glass, as the temperature required to transform it into a liquid is far lower (250°C compared to 1700°C).
Acrylic plastic also has excellent bonding properties, making it ideal for use with adhesives and solvents. It can be used with a range of adhesive tapes, such as synthetic rubber adhesive tape and acrylic adhesive tape, although the latter provides higher performance. Acrylic plastic is also available in a variety of sizes and colours, making it a versatile material for a range of applications.

Acrylic is easy to fabricate and bonds well with adhesives and solvents
Acrylic is a versatile plastic that can be easily fabricated into a variety of shapes and forms. Companies like Akrylix offer custom acrylic fabrication services, producing items ranging from food service trays to public art installations. Acrylic sheets can also be cut to size and used for various applications, such as displays, sneeze guards, and product holders.
When it comes to bonding, acrylic performs exceptionally well with adhesives and solvents. Low Surface Energy (LSE) plastics, including polypropylene, polyethylene, polystyrene, and EVA (ethylene vinyl acetate), are known for their soft and easily mouldable properties. However, their low surface energy makes them challenging to bond with adhesives. Acrylic, being a versatile material, can be effectively used in combination with adhesives to bond LSE plastics.
Modified acrylic adhesive systems, such as the 3M™ High Strength Acrylic Adhesive 300LSE, are specifically designed to bond LSE plastics without the need for surface modifications or primers. Acrylic foam tapes, for instance, can create long-lasting, high-strength bonds with LSE substrates, providing design flexibility and eliminating the need for mechanical fasteners. Acrylic-based adhesives are also commonly used in self-adhesive tapes due to their strength and durability.
Solvent acrylic adhesives, in particular, offer a wide range of advantages. They can be customised to meet specific performance requirements, offering extraordinary chemical resistance and the ability to withstand temperature extremes. Solvent acrylics are ideal for long-term applications where durability is crucial, such as bonding nameplates to outdoor equipment. They also excel in membrane switch technology, ensuring the functionality of switches in various conditions.
Water-based acrylic adhesives, on the other hand, are environmentally friendly, economical, and versatile. They are widely used in technical adhesive tapes due to their low volatile organic compound (VOC) content. The choice between solvent-based and water-based acrylic adhesives depends on the specific application requirements and environmental conditions.

Acrylic plastic is a fantastic alternative to glass
Acrylic is also a more economical alternative to glass. The manufacturing process of glass is complicated, extensive, and expensive. Glass is made from a combination of sand, soda ash, and limestone, heated to roughly 1700°C. It takes a lot of energy to reach and maintain this temperature. Acrylic sheets, on the other hand, can be produced at half the cost of glass. They are also lightweight, reducing transportation costs.
Acrylic is more optically clear than glass, transmitting up to 92% of light compared to 80-90% for glass. It is also easier to maintain this clarity with acrylic as it does not streak or smudge as easily as glass. Acrylic can be cleaned with a simple mixture of soap and water, whereas glass requires special anti-streaking cleaning solutions.
Acrylic is also a safer alternative when it comes to UV protection. Glass blocks UVB rays from the sun, which cause sunburn, but UVA rays, which cause premature skin ageing, can still penetrate through. Acrylic, on the other hand, has good natural UV resistance, protecting your skin and the colouring of the acrylic from damage. Acrylic sheets are also available with added UV filters for further protection.
With its superior strength, economy, optical clarity, ease of maintenance, and UV protection, acrylic plastic is a fantastic alternative to glass for a variety of applications, including windows, greenhouses, skylights, and store-front windows.

Acrylic plastic is half the weight of glass
Acrylic is a great substitute for glass in picture frames. Glass has been a trusted material for hundreds of years, but its brittleness and heavy weight can be limiting. Acrylic sheet, on the other hand, is much tougher, lighter, and easier to fabricate and form into various shapes. It also has greater impact strength than glass. If it breaks, it usually cracks into large pieces with less sharp edges compared to broken glass.
Acrylic is a better heat insulator than glass, feeling warm to the touch rather than cold. It also has a lower coefficient of thermal conductivity and superior light transmission. Its edges are pure water-white, unlike the dull grey or green edges of glass. Acrylic is also highly customizable, as it comes in a wide range of colours and can be decorated and treated in various ways.
In terms of strength, acrylic has lower tensile strength and stiffness than glass. As a result, acrylic requires a greater thickness to withstand the same wind loads and support the same weight. However, despite being less stiff, acrylic has greater impact strength and is more resistant to abrasion.
Acrylic is commonly used in signage, retail display cases, window glazing, aquarium tanks, protective barriers, face shields, decorative panels, furniture, and lighting fixtures. Its adaptability and aesthetic qualities make it a popular choice for commercial, industrial, and residential applications.

Acrylic can be cleaned with soap and water
Acrylic is a type of plastic that can be used for windows, furniture, and picture frames. It is known to be quite challenging to clean because it scratches easily and is sensitive to certain cleaning products. However, with the right technique and products, it can be cleaned effectively without causing any damage.
One of the safest and most recommended ways to clean acrylic is by using soap and water. It is important to use mild soap or a non-abrasive cleaner, as harsh chemicals can scratch or damage the acrylic surface. The soap should be mixed with lukewarm water to create a gentle cleaning solution. A sponge or a premium lint-free microfiber cloth can then be used to gently blot the acrylic surface, removing dirt and debris. It is important to avoid applying too much pressure or wiping vigorously, as this can also lead to scratches.
For acrylic windows, a microfiber cloth is ideal for gently blotting the surface clean. The cloth can be dipped in the soapy water solution, ensuring that any dirt or dust is removed without causing scratches. After cleaning, the window should be blotted dry with a separate dry microfiber cloth. This process can also be used for picture frames and other acrylic surfaces.
For acrylic furniture, a cleaner designed for plastic, such as Brillianize, can be used along with a microfiber cloth. Small areas should be cleaned at a time to prevent scratches. Additionally, for tubs or shower stalls, a soft sponge with warm water and a mild dish soap can be used for gentle scrubbing. Lemon can be used to remove hard water stains, followed by a rinse with water.
By following these steps and using soap and water along with gentle cleaning tools, acrylic surfaces can be effectively cleaned without causing any damage. It is important to remember that acrylic is sensitive and can be easily scratched, so gentleness and care are crucial when cleaning these surfaces.
