Abstract (en)
[origin: WO2008068296A1] A ground marking device, visible by night and by day, comprising a body to be buried in the ground and having filaments protruding onto the surface of ground, said device being characterized in that the filaments are made of a polymeric material comprising a polyamide base and a phosphorescent pigment. Preferably, the phosphorescent pigment is a lanthanide aluminate. Another object of the invention is a method of production of the polymeric phosphorescent filaments, wherein a mixture comprising a polyamide-based polymer and a phosphorescent pigment is submitted to a vertical extrusion through a crosshead PE-type nozzle, and to the drawing out of the resulting filaments. The device can be installed by simply pushing it into the ground.
