Paper Abstract

Polytetrafluoroethylene (PTFE), is a white fluoropolymer resin that can be represented by the chemical expression [CF2-CF2]fl. These resins are internationally used in the field of diffuse reflectance spectrophotometry. Many applications, such as 450/0° Bidirectional Reflectance Distribution Function (BRDF) standards, are dependent on a specialized method of sample preparation. An experimental method has been developed which includes a technique for transforming aggregates of PTFE resins into a fine high quality aerated powder. This paper documents our progress in the characterization of the properties of pressed PTFE powders for potential use in BRDF standards developement: selecting PTFE resins, pulverizing PTFE resins, pressing PTFE powders, and measuring the BRDF's of samples with different surface conditions.
