摘要 |
<p>A multi-layer electrostatic dissipative structure that is clear to translucent, washable and thermo-formable comprises at least one outer layer and a core layer. Preferably, two outer layers are utilized with the core layer sandwiched therebetween. The outer layers are a blend of amorphous or semi-crystalline copolyester and an electrostatic dissipative polymer in an amount sufficient to impart a surface resistivity of about 105 to 1012 Ohms/sq. The core layer is a polymer having a haze value of less than five percent, preferably amorphous or semi-crystalline copolyester. The multi-layer structure may additionally have tie layers between the core layer and each of the outer layers.</p> |
