Frequently asked questions
GF grades require higher injection pressures. Strongly anisotropic shrinkage (perpendicular to fibres > along axis). Increased nozzle and mould wear — nitrided steels recommended. Drying identical to base grade.
The PC is recyclable (code 7). Chemical depolymerisation allows for the recovery of BPA and diphenyl carbonate. Mechanical recycling is common in industry but degrades transparency and impact resistance after several cycles.
PC-FDA grades are approved for food contact. Beware of older grades that may contain BPA. Modern BPA-free grades comply with EU regulation 10/2011 for certain uses. Always check the specific grade.
