Flexible corrugated polyamide conduits (PA 6-D), designed for optimum flexibility, high compression resistance and excellent response to impact; ideal requirements in all applications for for the protection and insulation of electrical installations. Excellent resistance to most chemical substances such as oils (max. Temp. +80°C), petrol, acids and solvents. Self-extinguishing, with low toxicity and low smoke density. Halogen, silicone and cadmium-free. Low fume emission in case of fire makes these conduits particularly suitable for applications in the railway sector and in all places where there is a greater risk of fire. 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.
