PVC-M (Modified PVC) is essentially an alloy of the PVC-U polymer and several modifying agents that improve ductility as well as resistance to impact and crack growth. These improved material characteristics allow for a thinner wall, larger internal diameter and increased hydraulic efficiency than PVC-U pipe of the same nominal diameter and pressure class.


mPVC pressure pipe is distributed by Sizabantu Piping Systems (Pty) ltd though a network of Divisions throughout South Africa. It is also distributed to Southern Africa through Sizabantu Exports, which focusses on countries outside South African borders.
