ETFE Film
ETFE Film for Flexible solar PV
ETFE is a unique thermoplastic Fluoropolymers. It combines improved mechanical properties, great Mouldability, and excellent electrical properties and chemical resistance.
ETFE film is a high sophisticated film which is not including plasticizer or adhesive. Therefore the excellent properties of fluoro-resin appear directly. It is used in various fields such as electric, aircrafts, space, solar battery and kitchen equipments, because of high heat resistance, high chemical resistance, non stick and excellent electrical properties.
Product description and advantages
1,Outstanding Resistance to Weather and Ageing
2, High Transparency
3,Excellent Moisture Permeation Resistance
4,Stable and inert against most chemicals
