UV Resistant Plastics for Outdoor Applications | Curbell ...

Certain plastics such as acrylic, Ultem, PVDF, and PTFE are inherently UV stable. However, most plastic materials exhibit color change and loss of elongation when exposed to UV light. Weathering resistance of some plastics can be improved by adding UV stabilizers or UV resistant caps to protect the base polymer.

UV Properties of Plastics: Transmission and Resistance ...

PTFE has particularly good UV resistance because of its very strong carbon- fluorine (C-F) bond [almost 30% higher than the carbon-hydrogen (C-H) bond], which is the common side bond that surrounds the carbon (C-C) backbone in a helix and protects it.

UV Resistance - City Plastics

There are a number ofmethods to reduce this problem. The addition of carbon black to the polymerwill usually absorb most UV radiation. Chemical inhibitors are available forcertain plastics, which improve the UV resistance. Paint and silicone coatings can also be usedto completely cover exposed surfaces to sunlight (UV radiation).
