Polyurethane-elastomer spiral hoses affiliate excellent properties like very high flexibility, resilience, buckling reliability and high abrasion resistance. The weighting of stability to ultraviolet-rays and ozones is good to excellent. These hoses are electrically conductive up to diameter DN150 (based on the spring steel helix).
All configurations are taste- and odorless, resistant against microbes and indicate a high hydrolysis stability. There are no plasticizer or halogens applied. Therefore an FDA-approval is verifiable.
Abrasion involving solids, flours, powders, fibers, gaseous media, vapors and smoke could be conveyed easily.
Pictured are the structural shapes very light and light.
