Optical and Spectral Properties of Melt-processible Fluoroplastics

5 Optical and Spectral Properties of Melt-processible Fluoroplastics 

In applications where it is important to consider resolution, the data in Fig. 3.108 is more appropriate. Transmission of visible light through PFA film is similar to FEP.1 1 

PVDF films up to 100-125 pm are transparent to translucent when the molten polymer is quenched in water to minimize crystallization. The transmittance spectra of PVDF in the ultraviolet, visible, and 

The refractive index of pol5miers provides fundamental information that can be used in the analysis of parts, processing, and characterization. It has been demonstrated that the square of refractive index is related to the dielectric constant of a pol5mier, both in direction and magnitude.Table 3.84 shows the values of the refractive index of fluoroplastics, measured at a light wavelength of 589.3 nm and referred to as in literature.
