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.
PPS is difficult to recycle due to its high processing temperature and aromatic structure. Industrial recovery programmes exist from manufacturers. Not suitable for consumer recycling.
PPS is generally not certified for food contact. For high-temperature food contact, PEEK or PEI are preferred.
