white series eva film
f806w
product introduction
f•rst® f806w eva is a white encapsulant specifically designed for the backside encapsulation of normal pv modules and double-glass pv modules. it is used between cells and rear materials.
f•rst® f806w eva is characterized as highly reflective. its unique optical property can increase the effective utilization of light ultimately enhancing the power output of pv modules. f806w eva also provides a solution for white overflow appearance issues in processing of modules.
