ABSTRACT:
The present invention provides and employs a very thin yet highly light reflective material for use in providing diffuse reflectivity of light, especially in tightly confined applications such as in laptop computer displays. The present invention uses an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils combined with a coating or filler of material having a high index of refraction, such as titanium dioxide. The material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible and infrared light. Additionally, the material of the present invention provides many properties that have been previously unavailable in thin, highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at very thin cross-sections.
