About acrylic glass

Types of acrylic glass

Acrylic glass is also known as acrylic, a transparent thermoplastic. In a way, acrylic glass resembles glass, but it is lighter, stronger, and more shatter-resistant. It is also more affordable. People use acrylic glass for different applications, ranging from windows and skylights to signage, displays, and furniture. Below are some of the most common types:

  • Optically Clear Acrylic

    Optically clear acrylic is a type of acrylic that has very high optical clarity. Because of this property, people often use it in places where visual transparency is very necessary. Such places include display cases, signage, and windows. In addition to being clear, this acrylic is also resistant to UV light and continues to maintain its clarity and sheen even after long sun exposure.

  • Frosted Acrylic

    Frosted acrylic comes with a non-reflective surface that reduces glare and provides a softer, diffused light. This makes it ideal for things like lighting panels, signage, and decorative elements. In addition to that, the frosted finish also provides an etched look to the acrylic. This improves the aesthetic value of the places it is installed.

  • Colored Acrylic

    This acrylic type comes in a variety of colors. Therefore, it allows users to customize their projects based on individual needs and preferences. People mostly use colored acrylic in decorative applications. These applications include artistic displays, architectural elements, and signage. The density of its color varies, hence the possibility of it being translucent, opaque, or transparent.

  • Bullet Resistant Acrylic

    Bullet-resistant acrylic is created by bonding together multiple layers of acrylic or combining acrylic with other materials like polycarbonate. This gives it the strength to absorb the impacts of ballistic threats. Therefore, people use it in security applications. Some of these security applications include windows in banks, military vehicles, and threat assessment facilities. Although it is not as thick as traditional glass, it can still offer superior protection while remaining lightweight.

  • UV-Filtering Acrylic

    This acrylic is specifically designed to block harmful UV rays while still allowing visible light to pass through. It is ideal for protecting items that can easily get damaged by UV light, such as artwork, photographs, and antiques. In addition to blocking UV rays, this acrylic also helps prevent color fading and material degradation. This makes it a popular choice for museum displays and protective cases.

Why acrylic glass is popular

As noted, acrylic glass closely resembles real glass. However, it has more practicality. For example, since acrylic is over 92% as clear as glass, you can hardly differentiate it from glass. Other than that, acrylic is way more shatter-resistant, which is probably why it is much more popular. Below are some of the key reasons acrylic is popular:

  • Clarity and Transparency

    Acrylic sheet has high optical clarity. This means they allow nearly all light to pass through without distortion. This property makes it ideal for applications that require transparency, such as display cases, windows, and lenses. In addition, it comes with a shiny, glass-like finish that looks attractive in whichever application it is in.

  • Lightweight

    Compared to glass, acrylic is significantly lighter. While a one square foot of glass generally weighs around 2.7 pounds, the same measurement of acrylic weighs about 0.93 pounds. This makes it easier to handle, transport, and install, hence giving it more practicality. It is especially practical for large installations where weight is a major concern.

  • Impact Resistance

    While glass can easily shatter on impact, acrylic is more shatter-resistant. Specifically, acrylic is 10 to 20 times more impact-resistant than standard glass. This makes acrylic ideal for applications where safety is a priority. These applications include safety glasses, visors, and protective barriers.

  • Manufacturing and customization

    Makers can easily thermoform acrylic into complex shapes and designs to suit differing project requirements. This property allows for greater design flexibility compared to other plastics. Also, acrylic can be easily cut, drilled, and polished using standard tools. This simplifies the fabrication process for designers and manufacturers alike.

  • Weather Resistance

    Acrylic is resistant to harsh weather elements such as water, wind, and even UV radiation. That's why it is a go-to material for outdoor applications such as signage, greenhouse panels, and skylights. More importantly, it won't yellow or degrade over time due to sun exposure. This means it will always look clear and functional for a long time.

  • Cost-effective

    Acrylic is more affordable than glass in most cases. Whether it is for residential or commercial use, this provides a better return on investment. While it looks and feels like glass, it costs significantly less to purchase and install acrylic. So, people on a budget will go for it to enjoy the benefits of glass without the expenses.

How to choose acrylic glass

Several factors come into play when choosing acrylic glass. These factors directly influence the performance, durability, and appearance of the acrylic in its application. Below are some of these factors:

  • Thickness

    Acrylic sheets are available in numerous thicknesses. Each thickness is suitable for differing applications. For instance, thinner acrylic (1/8 inch to 1/4 inch) is ideal for lightweight frames, display cases, and machine guards. On the other hand, more substantial acrylic (1/2 inch to 1 inch) is suitable for structural applications, such as glazing, skylights, and architectural features. When selecting acrylic glass, consider the mechanical requirements of the intended use. Also, don't forget to consider the load-bearing requirements.

  • Type of acrylic

    Acrylic sheets come in either cast or extruded forms. Cast acrylic offers superior optical clarity, surface quality, and machining characteristics. This makes it highly suitable for high-end applications like optical devices and premium signage. On the flip side, extruded acrylic is more affordable and easier to work with. It is the go-to for DIY projects and low-cost applications. Although it has minor optical imperfections, it is still perfectly clear and functional.

  • Finish

    The finish of acrylic glass significantly affects its aesthetic appeal and functional properties. For instance, a glossy finish enhances clarity and sheen. Thus, makes it suitable for decorative and display purposes. However, a frosted finish reduces glare and provides a more diffused light. That makes it ideal for lighting fixtures and privacy screens. When choosing acrylic glass, buyers will have to consider the desired aesthetic effect and functional requirements. Do these two factors justify  the choice of finish?

  • Light transmission

    Acrylic glass offers wide-ranging light transmission options. These options range from nearly 100% to below 50%. Generally, clear acrylic provides optimal light transmission. It allows nearly all visible light to pass through. This property makes it ideal for illuminating displays and windows. On the other hand,opaque and tinted acrylics reduce light transmission. These t pros and cons are useful in controlling light and glare. They are especially useful in lighting applications or enclosures that require privacy.

  • UV resistance

    Acrylic glass is highly resistant to ultraviolet (UV) radiation. It helps in preventing color fading and deterioration of materials behind the acrylic. Nonetheless, not all acrylic sheets have the same level of UV resistance. Therefore, it is advisable to look for specifically marked UV-filtering acrylic. This type of acrylic is ideal for outdoor applications, exhibits, and any other long-term displays. It protects artwork, photographs, and other valuable items from UV-induced damage.
