More Information
Summary:The present disclosure is directed to laser-markable insulation material and cable or wire assemblies containing such insulation material. In certain embodiments, the laser-markable insulation material can include a fluoropolymer and an inorganic laser-markable pigment. The pigment can have a mean crystal size in a range of about 0.4 microns to about 2 microns and/or a median particle size (d50) in a range of about 0.45 microns to about 2 microns. The insulation material can exhibit improved initial and heat-aged contrast ratios without diminishing the ability of a cable or wire containing the insulation material to meet industry standards for electric-arc tracking and propagation resistance.
