CNCGLASS EVA film & SGP interlayer

This catalog describes CNCGLASS polyolefin (POE) encapsulant film for photovoltaic modules, used as a packaging material alongside EVA film for crystalline-silicon and thin-film cells. Low water-vapor passage, strong electrical insulation, and lasting PID resistance make it a sound choice for PID-sensitive cells, frameless double-glass modules, and single-glass modules in humid climates. Two optical arrangements are offered: a high-transmittance, PID-resistant grade toward the glass, with ultraviolet transmittance from 290 nm to 380 nm of at least 80 %, and a high cut-off, PID-resistant grade toward the backsheet, with ultraviolet transmittance in that band no higher than 30 %. In both cases, transmittance from 380 nm to 1,100 nm is at least 91 %. The catalog also lists typical properties, a 96-hour PID check, starting lamination cycles for single-chamber and two-chamber laminators, and storage and handling guidance. The full catalog is in the PDF below.

This catalog describes CNCGLASS high-permeability, PID-resistant EVA encapsulant film for the glass side of photovoltaic modules. The film holds the cells, lets sunlight reach them, and protects them outdoors; ultraviolet transmittance from 290 nm to 380 nm is at least 80 %, and transmittance from 380 nm to 1,100 nm is at least 91 %. Compared with an ordinary EVA encapsulant, that extra passage of light can raise module conversion efficiency by 1.5 % to 5 %. The catalog also lists typical properties, starting lamination cycles for single-chamber and two-chamber laminators, and storage and handling guidance. The full catalog is in the PDF below.
