Before exploring how to prevent yellowing, it's important to understand why acrylic turns yellow in the first place. The primary cause is the UV degradation of the material. Acrylic is a plastic, and like many other plastics, it reacts to prolonged exposure to UV light, causing a chemical change that leads to yellowing. Other factors, such as heat and certain environmental pollutants, can accelerate this process.
Here are the main reasons acrylic yellows:
UV Radiation: Exposure to sunlight causes the acrylic material to break down, resulting in discoloration.
Heat Exposure: Acrylic can soften and degrade over time when exposed to high temperatures, leading to yellowing.
Chemical Reactions: Exposure to certain cleaning products, solvents, or pollutants can react with acrylic, causing it to discolor.
Aging: Over time, even in the absence of significant exposure to UV or heat, acrylic will naturally age and can develop a yellowish tint.
Acrylic plastic sign holders can yellow over time due to UV radiation, heat exposure, and environmental pollutants.
UV-resistant acrylic is the best option for preventing yellowing in outdoor applications.
Regular cleaning with non-abrasive solutions helps prevent damage and yellowing of Acrylic Signage & Displays.
Store acrylic products properly in cool, dry places to avoid exposure to heat and sunlight.
If yellowing occurs, use acrylic polish or a baking soda paste to restore the material’s clarity.
Acrylic is one of the most popular materials used for creating acrylic signage & displays, acrylic stand displays, and acrylic plastic sign holders due to its clarity, durability, and lightweight nature. However, over time, acrylic can begin to yellow, especially when exposed to UV rays, heat, and environmental factors. This discoloration not only affects the aesthetic appeal of acrylic stands for display but can also impact the overall appearance of your displays.

While yellowing in acrylic is common, there are several ways to prevent it from happening in your acrylic display or acrylic stands for display. Here are practical tips that will help maintain the clarity and freshness of your acrylic plastic sign holder for an extended period.
When selecting acrylic for your acrylic signage & displays or acrylic stand displays, consider using acrylic sheets that come with built-in UV protection. These acrylic products have a special coating or additive that blocks harmful UV rays, reducing the risk of yellowing.
UV-blocking coatings: Some acrylic products come with a UV-resistant coating that prevents UV rays from damaging the material.
UV-resistant acrylic sheets: Opt for acrylic sheets specifically designed to be resistant to UV light. This acrylic is less likely to yellow compared to regular acrylic.
By using UV-protected acrylic, you can significantly increase the lifespan of your acrylic stands for display and other acrylic products.
One of the most effective ways to prevent yellowing in acrylic plastic sign holders is to limit exposure to direct sunlight. UV rays from the sun are the primary cause of yellowing in acrylic. When placing your acrylic display or acrylic signage & displays, consider positioning them away from windows or places with strong sunlight exposure.
Indoor displays: Keep your acrylic stand display indoors, where sunlight exposure can be controlled.
Use curtains or blinds: If your displays are near a window, use curtains or blinds to block UV rays during the day.
When cleaning acrylic stands for display or acrylic plastic sign holders, it’s essential to use gentle, non-abrasive cleaning solutions. Harsh chemicals and abrasive cloths can scratch the acrylic surface, creating grooves that trap dirt and pollutants. These grooves can accelerate yellowing by allowing more UV light to penetrate the surface.
Mild soap and water: Use a mixture of mild dish soap and lukewarm water to clean your acrylic products.
Microfiber cloth: Always use a soft, microfiber cloth to wipe down acrylic. Avoid using paper towels or rough fabrics, which can scratch the surface.
For deeper cleaning, you can use a specialized acrylic cleaner that is designed to protect the material and prevent yellowing.
