PA (Polyamide) 12
✓ This material meets the criteria ~ Specialized grades may meet this criteria
| Density | 0.930 to 1.18 g/cm³ ISO 1183 |
|---|---|
| Charpy notched impact | 2.5 to 9.3 kJ/m2 |
| Flexural modulus | 1400 MPa |
| Flexural resistance | 60 MPa |
| Tensile modulus | 1600 MPa |
| Tensile resistance | 50 MPa |
| Tensile strain | 200 % |
Injection at 210–250 °C, mould at 40–80 °C. Recommended pre-drying: 4 hours at 80 °C. Good flow properties. Moderate shrinkage (0.9–2.0 %). Less hygroscopic than PA6 → better dimensional stability after moulding.
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.
Choose the right material for your application by comparing Polyamide 12 to alternatives on thermal, mechanical, chemical and cost criteria.
