Description
Solid Makrolon® DX sheets are polished polycarbonate diffuser sheets. Makrolon® DX is developed for applications based on LED light sources, which do not emit UV light. It offers a combination of high light transmission and light diffusion as well as an extreme impact strength which exceeds the physical properties of other thermoplastics. Makrolon® sheets resist tempe-ratures of -100 to +120 °C. Makrolon® DX cool is a diffuser sheet with a cool and fresh color appearance, even when the LEDs are in off mode
Benefits
- Extreme high light transmission and high diffusivity at the same time
- Extreme impact strength
- Resistance to wide range of temperature
Features
- Cool and fresh color appearance, even when the LEDs are in off mode.
- High light transmission and light diffusion
- Makrolon® sheets resist temperatures of -100 to +120 °C.
Recommended Uses
- Typical applications for Makrolon® DX diffuser sheets include all kinds of LED lighting fixtures and luminaires. The sheets offer protection against involuntary breakage and willful destruction therefore can also be applied in LED-based signage applications and street furniture where efficient lighting technologies are in use. Makrolon® DX sheets can be thermoformed, cold-curved and fabricated with ease.
