| Product Grade | EH 7 |
| Applications | Pipes for long-term usage at normal and higher temperature applications, such as drinking water and drain pipes Related fittings Rods, profiles Mono- and multilayer sheets |
| Product Description | HIPOLEN P EH 7 is very low flow homopolymer with excellent resistance to organic solvents and very low moisture absorption rate. Grade EH 7 is designed for extrusion processes which demand high melt strength and enhanced processing stability. Advantages of end use products are high heat-ageing stability, good extraction stability and high chemical and corrosion resistance. Pipes and fittings made from EH 7 are intended for transfer of hot liquids or gases at normal and medium pressures. |
