摘要: A process for the extrusion of plastic plates with very finely structured surface using an system which is equipped extruder and a three roll polishing stack containing roller structuring surface. The designed coextrusion are produced via two extruders as coextrudate CX from highly viscous basic molding compound BF low viscosity NF extruded on BF. said stack. Fresnel lenses by may be used in solar collectors.
