Laser Printing on Black Low-Shrink HDPE for the Sheathing of Fiber Optic Cables

摘要

Laser printing of black polymer surfaces is tricky as the laser does not leave enough contrast on black to have readable fonts. New technology has been developed on the basis of low shrink bimodal HDPE, which has been established on the market for FOC cables in the past decade. The new formulation also provides excellent contrast for laser printing.
