Ultraviolet (UV) Reflectors
Maximize performance with UV reflectors
For ultraviolet light reflectivity, manufacturers trust our POREX Virtek sintered PTFE sheets and molded 3-D parts. With over 97% average reflectance from 250nm to 400nm, POREX Virtek® pure PTFE reflectors can maximize disinfection rates and minimize system cost.
Specifically designed for UV systems, our UV reflectors:
- Eliminate hot and cold spots – POREX Virtek PTFE scatters light in all directions, spreading UV light evenly across a surface and eliminating cold spots where bacteria may survive.
- Maximize lighting efficacy – With over 97% average reflectance from 220nm to 400nm, less light is lost to absorption.
- Maintain performance in high temperatures – Working temperature of POREX Virtek PTFE is 260ºC.

Specialty Lighting Reflectors
High-performing reflectors for specialty reflectivity applications
Specialty lighting applications require high-performing reflectors, that efficiently mix and diffuse light. Our POREX Virtek specialty lighting reflectors:
- Eliminate hot and cold spots – POREX Virtek PTFE scatters light in multiple directions, spreading and mixing the light evenly across a surface and eliminating hot spots and increasing color uniformity.
- Maximize lighting efficacy – With over 97% average average reflectance over the entire light spectrum, our reflective material captures wasted light and delivers it to the lighting task.
- Maintain performance in high temperatures – Working temperature of POREX Virtek™ PTFE is 260ºC.
