Flexible corrugated polyamide conduits (PA6 - PA12) of large dimensions, designed for optimum flexibility, and good mechanical characteristics such as solidity, compression strength and impact resistance; ideal requirements in all applications for the protection and insulation of electrical installations. The high resistance to repeated bending, makes them particularly suitable for dynamic applications (code 5001). Excellent resistance to most chemical substances such as oils, petrol, acids and solvents. Self-extinguishing and halogen, silicone and cadmium-free. Corrugated internal and external surfaces ensure an excellent sliding of the cables, significantly easier than with flexible PVC conduits. The product offers good resistance against UV rays.
