Exploring UV Resistance

One of the most common questions we receive is regarding UV resistant plastics. At Associated Plastics, we understand the importance of UV resistance in materials, especially for outdoor applications. Here’s a breakdown of the UV resistance of three commonly used plastics: acrylic, polycarbonate, and HDPE.

Acrylic Sheet

Acrylic sheets are known for their excellent UV resistance, making them ideal for outdoor use. They can withstand prolonged exposure to sunlight without yellowing or losing their clarity. This UV resistance is inherent in acrylic, providing long-term durability and aesthetic appeal for various applications, including signage, outdoor displays, and architectural projects.

Polycarbonate Sheet

The polycarbonate sheets we stock are equipped with a UV coating on both sides, significantly enhancing their UV resistance compared to standard polycarbonate. With proper UV coatings, polycarbonate sheets can maintain their clarity and strength for years in outdoor applications such as greenhouse glazing, skylights, and protective barriers.

HDPE Sheet

HDPE (High-Density Polyethylene) sheets typically lack UV resistance, unlike acrylic. Natural HDPE, when exposed to sunlight for extended periods, may experience color fading and surface degradation. However, black HDPE, which is UV stabilized during manufacturing, offers improved resistance to UV rays. This makes it suitable for various outdoor applications in the marine, mining, and agriculture industries.
