| 摘要 |
A plastics material is prepared from a plastics material blend comprising PET or other plastics material in granular form, glass material in particle or fibre form and other processing aids. The scratch resistance of the plastics material prepared from the blend is significantly enhanced, and its temperature stability, impact resistance, fire resistance, ultraviolet stability and chemical inertness are also enhanced. Sheets of the plastics material with high scratch resistance are extruded and coextruded with unblended plastics materials which form a substrate or substrate core.
