Polyamide 12 is one of the most commonly used materials in machining techniques due to its flexibility and mechanical qualities.

This polyamide is different from other materials due to its high mechanical properties and good heat resistance. A low level of water absorption, resistance to hydrocarbons and oils and its high resistance to chemical agents complete its range of really excellent properties.

This material is highly suitable for all mechanical applications that require high performance: from traction to alternating bending, as well as in the field of robotics and pneumatics.
