Abstract

Procedure for obtaining a strip of poly- ε -caprolactam sheet or its copolymers, which are composed of more than 70% caprolactam; characterized in that a polycaprolactam with a relative viscosity of 2.4 to 3.3, preferably 2.5 to 2.8, containing evenly and finely distributed 0.0005 to 0.5%, preferably 0.001 to 0.01% of silicates crystalline magnesium particles with a particle size of less than 30μm are extruded through a wide-slot nozzle onto a cooling cylinder and the melt exiting the wide-slot nozzle is extracted at an extraction rate greater than 30m/min of the cooling cylinder, forming a sheet with a thickness of less than 50μm.
