Nitrile Rubber

Nitrile Rubber Overview

Nitrile rubber is a synthetic rubber copolymer made of acrylonitrile and butadiene which can have varying properties depending on the acrylonitrile percentage. Nitrile rubber is also known as Buna-N, Perbunan®, acrylonitrile butadiene rubber, and NBR. It also has trade names including Nipol®, Krynac®, and Europrene®. Laser processing of nitrile rubber is possible with either a 9.3 or 10.6 micron CO2 laser without any appreciable difference in processing quality. Nitrile rubber does not readily absorb the energy of a 1.06 micron fiber laser and is not recommended for this material. Laser cutting of nitrile rubber with a CO2 laser results in a wide cut with sharp edges, having some discoloration at the edge. Laser engraving of nitrile rubber can be performed with a CO2 laser to create some depth and minimal residue. Laser marking of nitrile rubber is not possible with the 1.06, 9.3, or 10.6 micron wavelengths.
