EVA Interlayer

Features

Introduction

EVA-Films-Are-Becoming-More-Important-For-Glass-Laminating.png

EVA film is a revolutionary new type of interlayer for glass and plastic sheet lamination and encapsulation. It is one of the best alternatives to costly PVB due to quite a number of advantages.

EVA stands for ethylene vinyl acetate. EVA resin, together with a number of ingredients, is heated and mixed thoroughly and is then extruded through a flat die of a special design plastic extruding machine. EVA film is then formed. It is finally wind up in roll for storage and packing.

This extraordinary adhesive is non-sticky and inert to water moisture. Handling and glass assembly could be done under room temperature. No air conditioner and no de-humidifier are required.
