Why Is Cast Acrylic Sheet Resistant to Yellowing from UV Exposure
2025-11-27
At BE-WIN Group, we are often asked why our Cast Acrylic Sheet maintains its crystal clarity for years, even under direct sunlight. The secret lies in its superior manufacturing process and built-in UV resistance. Unlike ordinary plastics that degrade and turn yellow, our acrylic is engineered for long-term performance.
The exceptional weatherability of our Cast Acrylic Sheet is a result of several key factors:
-
Inherent UV Stability: The chemical structure of the polymer itself acts as the first line of defense, absorbing UV radiation without significant breakdown.
-
Integrated UV Absorbers: During the cell casting process, we integrate advanced UV-absorbing additives directly into the liquid monomer. This ensures uniform protection throughout the entire thickness of the sheet, not just on the surface.
-
High-Grade Raw Materials: We use only the purest raw materials, which minimizes impurities that can act as catalysts for photo-degradation.
Here are the key technical parameters that define our product's quality:
| Parameter | Specification | Benefit |
|---|---|---|
| Light Transmission | Up to 92% | Maximizes natural light while reducing the energy from UV rays that cause fading. |
| UV Stabilizer Content | Fully Integrated | Provides consistent, lifelong protection against yellowing and brittleness. |
| Surface Hardness | > 90 M Scale | Offers exceptional scratch resistance, maintaining optical clarity and aesthetics. |
| Service Life Outdoor | 10+ Years | A guaranteed long-lasting solution for outdoor applications without loss of clarity. |
Cast Acrylic Sheet FAQ
What is the main advantage of cast acrylic over other types for outdoor use?
The primary advantage is its superior resistance to yellowing and weathering. The casting process allows for the integration of UV stabilizers throughout the entire sheet, creating a homogenous protective barrier that extruded acrylic or polycarbonate cannot match.
Can BE-WIN Group's cast acrylic sheet withstand extreme weather conditions?
Absolutely. Our Cast Acrylic Sheet is rigorously tested to perform reliably in a wide range of climates, from intense, sun-drenched environments to coastal areas with high salt content. The material retains its impact strength and does not become brittle over time.
How does the UV resistance in your acrylic sheet protect against color fading?
The integrated UV absorbers in our sheet filter out the damaging ultraviolet spectrum of sunlight. This not only protects the acrylic itself from yellowing but also significantly reduces the fading of fabrics, prints, and materials placed behind it, making it ideal for signage and displays.
