Flexible corrugated polyurethane conduits, designed for optimum flexibility, and good mechanical characteristics also at low temperatures and high abrasion resistance; ideal requirements in all applications for the protection and insulation of electrical installations. Excellent resistance to microbes and to most chemical substances such as oils, petrol, acids and solvents. Self-extinguishing, 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.
