PC examples of elastic modulus retention versus sub-zero temperatures C

Glass transition temperatures are high, roughly 150°C for general-purpose grades and 160-200°C for heat-resistant grades. [Pg.442]

These results relate to some grades only and cannot be generalized. [Pg.442]

Amorphous polycarbonate is transparent with light transmittance ranging from 80% up to 91%, a haze of roughly 0.7-1.5% and a refractive index of about 1.58-1.586. [Pg.443]

Some self-lubricating grades of polycarbonate are marketed, containing specific additives and reinforced with glass or carbon fibres. The coefficients of friction are in a good range, from 0.1 up to 0.21. Wear resistance is not as good as for PA 66. [Pg.443]
