New PE-RT resin completes portfolio used in hot water pipe applications
ROTTERDAM, Netherlands, February 16, 2008 – LyondellBasell Industries has launched a new raised-temperature-resistant polyethylene resin (PE-RT) to complete its range of materials used in plumbing and underfloor heating. Produced using LyondellBasell’s Advanced Cascade Process (ACP), the new Hostalen 4731B high density PE resin exhibits excellent long-term creep performance and thermal stability and can therefore be taken into consideration for pipe applications. The PE-RT Type II material, which meets ISO standard 24033, is the latest addition to LyondellBasell’s range of cross-linked polyethylene, random copolymer polypropylene and polybutene-1 materials used in demanding applications such as hot water pressure pipes. Competitive Alternative “Critical to the performance of PE-RT resins is their ability to withstand a designed stress level over several decades at elevated temperatures. Our Hostalen 4731B resin provides this performance without cross-linking requirements, thereby offering a cost-effective alternative to a market traditionally dominated by cross-linked polyethylene,” explained Hansjörg Nitz, LyondellBasell’s Global Pipe Business Development Manager. The Hostalen 4731B resin also provides good processability. “Manufacturers can achieve high line speeds with smooth pipe surfaces. The high-melt strength properties of the resin result in very good dimension stability of the extruded pipe, which allows thin-wall pipes within small tolerances. The resin can also be processed on HDPE and PP-R equipment,” said Nitz. Multimodal resins The Hostalen 4731B resin is available in all regions except North America.
