PA12 offers excellent resistance to fuels, hydraulic oils, greases and aliphatic solvents. Its low water absorption provides superior dimensional stability to PA6/66. Sensitive to strong concentrated acids.
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.
PA12 is recyclable. In selective laser sintering (SLS), used powders can be recycled up to 30–50%. Mechanical recycling is possible for injection-moulded parts.
PA12 grades are approved for food contact (FDA 21 CFR, EU Regulation 10/2011). Verify the compliance of the specific grade with the food type and temperature.
