The density of polyamide (PA) depends on the specific type and grade of PA. It can vary significantly based on factors like:

* Polymerization type: Homopolymers (PA6, PA66) generally have different densities than copolymers.

* Filler content: Adding fillers like glass fibers or carbon black increases density.

* Modification: Reinforcement, stabilization, and other modifications can influence density.

* Manufacturing process: Molding, extrusion, and other methods can slightly alter the density.

Typical Density Ranges:

* PA6: 1.12 - 1.15 g/cm³

* PA66: 1.14 - 1.16 g/cm³

* PA6/66: 1.12 - 1.15 g/cm³

* PA12: 1.00 - 1.02 g/cm³

Note: These are just general guidelines. To get the exact density for a specific type of PA, refer to the technical data sheet provided by the manufacturer.
