Many plastics routinely exposed to the sun are at risk of ultraviolet (UV) light damage. The light erodes the polymers' chemical bonds, degrading the material over time. Fortunately, some materials have high UV resistance, making them excellent choices for environments with heavy sun exposure. From HDPE plastics to polycarbonates, here are some of the most resistant options on the market.

A Brief Guide to UV-Resistant Plastics

1. HDPE Plastics

High-density polyethylene (HDPE) is a thermoplastic, which is a petroleum product that is pliable and moldable at extremely high temperatures before turning solid upon cooling. In addition to its high level of UV resistance, this type of plastic repels acids, alcohols, and many other corrosive substances. 

It's a popular material due to its versatility, so you can find it utilized for various everyday products. Common uses include food packaging, kitchenware, toys, outdoor furniture, and playground equipment.

2. Polycarbonates

This thermoplastic option contains carbonate groups in its chemical makeup. It easily withstands significant impacts and temperature fluctuations. 

A concern with polycarbonate, however, is that it's more expensive than other materials. For this reason, it's typically only used for products that demand a high and reliable degree of safety, such as windows, helmets, and surgical instruments.

3. Acrylics

This material is a type of thermoplastic that contains one or more derivatives of acrylic acid. It has natural UV- and scratch-resistant qualities, and routine sun exposure triggers little breakdown—even over the long term. 

Acrylic is known to be rigid and rather delicate. As such, it often isn't the best choice for applications that bear heavy loads or must last for an inordinately long time. Instead, it's better suited for items like outdoor signs, light fixtures, and decorative panels.
