Neoprene™ rubber, also known as polychloroprene, is a synthetic rubber created by the polymerization of chloroprene. Laser processing of Neoprene™ rubber can be done with either a 10.6 or 9.3 micron CO2 laser with no appreciable difference. Neoprene does not readily absorb the energy of a 1.06 micron fiber laser and is not recommended for this material. Laser cutting of Neoprene rubber with a CO2 laser produces a smooth cut with sharp edges. At times, laser cutting will produce a slight discoloration and tackiness around the edges which can be cleaned after processing. Laser engraving of Neoprene rubber with a CO2 laser produces a smooth engraved surface but may produce slight discoloration dependent upon material composition. Laser marking of Neoprene is not recommended with the 1.06, 9.3, or 10.6 wavelengths as a contrasting mark is not produced.
