The introduction of Iplex Plastics

The introduction of Iplex Plastics

Founded as Industrial Plastics Ltd (I.P.L) by Otto Menzel in the 1930’s. Menzel wanted a trade name and his son Bill suggested adding an ‘EX’ at the end.  Iplex Plastics was formed and played a leading role in the development of fabricated plastic components over many years. In 1962, Iplex Plastics were a pioneer in the introduction of plastic pipes into the Australian market.
