lnterplast was established in 1981 to manufacture PVC compounds and over the years has developed an extensive range of compounds for different applications such as sidings, pipe fittings, cable insulation, sheathing, containers, rigid and flexible profiles as well as clear tubing. In 1983, Interplast diversified into converting compounds into finished products with the introduction of DECODUCT Electrical Cable Management Systems. Starting with uPVC Conduits, Trunking and Fittings, Interplast has since added many new products to its electrical range.Major additions were Underground Cable Protection Systems and a range of wiring devices marketed under the trade names of INTERGARD and EDISON respectively and a full range of metal trunking and cable trays complete with accessories in co-operation with its sister company TSSC.
