<strong>GORE®</strong> <strong>DRP®</strong> <strong>Diffuse</strong> <strong>Reflector</strong><br />
material<br />
GORE ® DRP ® <strong>Diffuse</strong> <strong>Reflector</strong> Material can improve luminance<br />
by over 30%. Every time light reflects, some energy is lost. Most<br />
designs require light to reflect several times. Therefore, a poor<br />
reflector absorbs a substantial amount of energy.<br />
Why are <strong>Gore</strong> ® DRP ® <strong>Diffuse</strong> <strong>Reflector</strong>s<br />
so Reflective?<br />
The answer lies in the micro porous structure. Light refracts<br />
from fibril to fibril. This is the same reason that snow reflects so<br />
much more light than water. The microstructure, optimized for<br />
maximum reflectance, is made from highly stable, chemically<br />
inert PTFE.<br />

<strong>Gore</strong> ® DRP ® <strong>Diffuse</strong> <strong>Reflector</strong> Material<br />
Our unique material science technology offers a product<br />
with exceptional reflectance properties. The reflectance of<br />
these materials is high, greater than 97.4% within the visible<br />
wavelengths, and diffuse, meaning that it's highly non-directional.<br />
These two features yield a material with the highest known diffuse<br />
reflectance. Additionally, these materials are remarkable stable<br />
within a wide range of operating conditions, including extremes<br />
in temperatures, in aggressive chemicals, and in long term UV<br />
exposures.<br />
These materials are available in sheet form and can be specified<br />
in a range of thicknesses and reflectance properties. These sheets<br />
are easily sized to any desired final dimension through standard<br />
cutting techniques (no machining required) The material can be<br />
supplied with a preapplied pressure sensitive adhesive for ease<br />
of installation.<br />
