Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [ 8 ] so it softens gradually above this point and flows above about 155 °C (311 °F). [ 9 ]
