Delrin®

Delrin® Overview

Delrin® is a polyoxymethylene (POM) based thermoplastic developed by DuPont. It is also known by other names such as acetal, polyacetal and acetal homopolymer. Laser cutting Delrin® with a 10.6 micron wavelength CO2 laser produces clean cuts with smooth edges. Laser engraving Delrin® with a 10.6 micron wavelength CO2 laser can produce a high degree of detail and relief. A 1.06 micron wavelength Fiber laser can be used to laser mark Delrin® in certain cases. The carbon based pigment in black Delrin® is heated by the laser beam, causing the surrounding polymer to foam. The foam scatters light creating an off-white, indelible mark in the Delrin® surface.
