EMS-Grivory Grilamid® L 25 Z PA12-I
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 12 (PA12)
Material Notes:	Product Description: Grilamid L 25 Z is a UV- and heat stabilized high viscosity polyamide 12 grade with improved toughness. A special feature of Grilamid L25 Z is its high energy absorption capacity Application examples: Grilamid L 25 Z has been designed for protecting aerial cables from shotgun damage. Due to its outstanding toughness, the integration of a layer of Grilamid L 25 Z in an aerial cable improves its shotgun protection and allows reduction of other costly armoring.
