Polypropylene (PP) is a thermoplastic commonly referred to as a polyolefin. Commercially available products based on polypropylene include Formex™ and Statex™. Polypropylene can be processed with a 9.3 or 10.6 micron UV laser without an appreciable difference in process quality. Polypropylene does not readily absorb the energy of the 1.06 micron fiber laser. Cutting of polypropylene can be performed with a UV laser to produce a clean non-discolored cut with a slight raised edge near the point of ablation. Laser engraving and laser marking of polypropylene are possible using a UV laser. However due to the relatively low melting point of polypropylene, this can lead to localized melting and a non-uniform surface at the point of laser interaction.
