At NPE 2009 in Chicago, PolyOne Corp., Cleveland, launched a global portfolio of low-smoke-and-fume, zero-halogen (LSFOH) compounds for indoor fiber-optic wire and cable applications. (These uses are known as FTTB and FTTH.) These compounds, both rigid and flexible, are based on polyolefins and mineral hydrates.
- ECCOH 6638 is for tight-buffering or loose-tube cables, as well as sheathing. It offers low corrosion, very low shrinkage (under 1%), good strength, and low memory retention.
- ECCOH PF 2037 and PF 4142 are for mini-ducts through which fiber is routed. Good stiffness eases installation and provides bend radius control.
- ECCOH PF 1045 is a flexible grade for mini-duct outer sheathing.
- Antistatic slip compound can be coextruded as a thin inner layer for mini-tubes to enable optical fibers to be blown further.
- ECCOH PF 4130 is an injection moldable compound for junction boxes.
Earlier this year, PolyOne also introduced two ECCOH grades for solar-panel cables. ECCOH 5944 meets UL 4703 standards for North America and Asia, while ECCOH 5943 meets European TUV 2 specs. Unlike TPU and TPV cable compounds, these ECCOH grades permit use of a single material for both internal insulation and external sheathing. Also, they offer a choice of crosslinking by dry silane or more costly e-beam.
