 Technical Data   


High-viscosity, heat- and light-stabilized polyamide 12 resin

VESTAMID L2170 has been designed especially for the extrusion of cable sheathings, but it can be used advantageously also for the manufacture of semi-finished products like tubes, rods, sheets, and profiles.

As a partially crystalline Polyamide 12, VESTAMID L2170 exhibits a low coefficient of friction which eases the installation of cables in ducts. Sheathings made of VESTAMID L2170 protect direct buried cables from attack by termites and rodents, due to their tough and smooth surface finish.

Because of low water absorption parts produced from VESTAMID L2170 maintain their dimension in environments with varying humidity levels, while maintaining a high toughness, a low coefficient of friction and good chemical resistance.
