Optical Properties Characterization of Thermoplastics Used in Laser Transmission Welding: Scattering and Absorbance

Abstract:

Article Preview

A better understanding of the optical properties of plastics at IR wavelengths is important for optimizing the laser transmission welding process. In this study, the optical properties, scattering and absorbance, of polypropylene (PP), polycarbonate (PC) and polyamide (PA) were investigated by using spectrophotometer with integrating sphere. The influence of thickness, surface roughness and filler content on optical properties of thermoplastics was evaluated. The results could contribute to a better understanding of the process itself and to success in the practical applications.
