| ALCUDIA® CA-7220B is stabilized with HALS (colourless), UV absorber and antioxidants. The main properties of these compound films are high solar radiation resistance, light transmission and heat retention. APLICATIONS Films for greenhouses and tunnels cover. 200 µm thickness, 1:2:1 three layers coextruded films, with ALCUDIA® CA-7421B in the middle layer and ALCUDIA® CA-7220B in the external layers, have a lifetime of the three years in geographical areas where maximum solar radiation is 160 Kly. For further information, contact to Technical Assistance and Development Department or Commercial Attention Service. Processing conditions should be optimized for each production line because of different rheological properties in coextruded structures.&& |
