NEOPREN strain support rubber flex

NEOPREN strain support rubber flexible multicore cables are designed for outdoor use where long lengths are installed without the use of messenger supports. They are ideal for use as trailing control cables and are commonly utilised in handling and hoisting gear, elevators, construction machinery, machine tools and other machinery where there is a  need to relieve stress. 

These NEOPREN strain support rubber cables are weatherproof and thus suitable for use indoors or outdoors including applications where the cable is exposed to adverse conditions, for example: in shipyards, steelworks, scrap yards, dockyard installations and conveyor systems. 

These cables are not suitable for drum reeling installations (where cable is continuously reeled in and out on pulleys or drums under tensile loads).

PCP or Neoprene Rubber (Polychloroprene) Properties: this self-extinguishing compound has excellent resistance to oxygen, ozone and water. It also has very good resistance to acids, alkalis and solvents plus good abrasion resistance.
