UV Transmittance and Blocking
-
UV Transmittance
- PMMA is a transparent material that stays weather resistant under prolonged UV ray exposure. PMMA products for outdoor application come with a trace of UV stabilizer for boosted weather resistance.
- A UV stabilizer-free version is available for applications requiring UV transmittance, and provides high transmittance of UV rays and visible light.
-
UV Blocking
- PMMA is a transparent material that stays weather resistant under prolonged UV ray exposure.
- PMMA sheets are available in a UV-blocking version also, and are ideal for protecting the surface materials underneath their installation. Blocks UV rays by up to 380nm.
