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 based on a copper wire (type MK-4).
All configurations are taste- and odorless, resistant against microbes and indicate a high hydrolysis stability. There are no plasticizer or halogens applied, therefor 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 MK-3 and MK-4 (with copper-wire).
