Acrylic sheets are widely used in industries such as construction, advertising, interior design, and furniture manufacturing due to their clarity, durability, and weather resistance. However, one common issue businesses face is the yellowing or discoloration of acrylic over time.
Several factors contribute to this phenomenon, including UV exposure, environmental pollutants, heat, and improper maintenance. Understanding the causes and adopting preventative measures can help businesses and manufacturers maintain the optical clarity and aesthetic appeal of acrylic sheets for years.
As a leading manufacturer, Jinbao Plastic provides high-quality acrylic sheets that are engineered for UV resistance and long-term durability. With over 35 production lines and a monthly capacity of 2,100 tons, we serve businesses worldwide that require premium acrylic solutions for a variety of applications.
This guide explores the causes of yellowing and provides effective strategies to prevent discoloration and extend the lifespan of acrylic sheets.
One of the biggest culprits behind acrylic yellowing is prolonged exposure to ultraviolet (UV) radiation from the sun. Standard acrylic is susceptible to photodegradation, where UV rays break down the polymer chains, causing a visible yellow tint over time.
Acrylic sheets exposed to high temperatures or direct heat sources for extended periods can degrade and discolor. This is common in industrial settings, outdoor signage, and high-heat applications.
Certain chemical cleaners, air pollutants, and industrial fumes can interact with acrylic and cause surface discoloration. Over time, exposure to chemicals like solvents, ammonia-based cleaners, and harsh acids can accelerate yellowing.
Not all acrylic sheets are designed for long-term exposure to sunlight and harsh environments. Non-UV-resistant acrylic will degrade much faster than premium, UV-stabilized acrylic sheets.
Using abrasive materials or harsh chemicals can damage the surface, leading to micro-cracks where dirt and pollutants accumulate. This accelerates discoloration, reducing the lifespan and clarity of the acrylic.
The most effective way to prevent yellowing is to use UV-stabilized acrylic sheets. Jinbao Plastic’s premium acrylic sheets are manufactured with UV inhibitors that protect against sun damage, ensuring long-lasting optical clarity and color retention.
For outdoor applications like signage, windows, and skylights, always opt for UV-coated or UV-absorbing acrylic sheets, as they significantly slow down the aging process.
To reduce thermal aging, install acrylic in areas away from excessive heat sources, such as hot machinery, industrial lighting, and prolonged direct sunlight. If acrylic must be used in high-temperature environments, consider heat-resistant acrylic variants.
To maintain acrylic’s transparency and prevent surface damage, follow these cleaning tips:
Use a soft microfiber cloth to wipe away dust and dirt.
Clean with a mild soap solution or an acrylic-safe cleaner.
Avoid ammonia-based products (like window cleaners) as they can cause cloudiness.
Never use abrasive scrubbers or harsh solvents, as they can create micro-cracks that trap dirt.
For acrylic surfaces exposed to outdoor conditions, applying a UV-protective coating or film can enhance durability. These coatings provide an extra barrier against UV radiation, heat, and pollutants.
If acrylic sheets are not immediately used, store them in a cool, dry area away from direct sunlight and heat sources. Covering sheets with protective film can also prevent premature aging.
Routine inspection of acrylic installations can help detect early signs of discoloration. If any areas appear yellowed or cloudy, consider polishing the surface with an acrylic restorer or replacing the affected sections.
