Polyamide tubes type T-PA12 are for technical applications due to theirs characteristics of flexibility and mechanical performances. These tubes show high mechanical properties to traction and to continuous & alternate flexion, notable flexibility, good stability to heat, remarkable resistance to aging, low water absorption, remarkable resistance to hydrocarbons and oils and good inertness to chemical agents. This kind of materil is particularly indicated for the accomplishment os tubing for pneumatics, robotics, steel, industrial machinery, etc., when there is the necessity to remarkeable flexibility.
