Vestolen A RELY family of tough, sustainable and cost-effective bimodal high-density polyethylene (HDPE) materials for pressure pipe applications introduced by Sabic. The SABIC® Vestolen A RELY portfolio offers converters considerable energy savings and enables environmentally responsible pipe installation. Further demonstrating its commitment to sustainable technologies, the company also presented today its revolutionary new Strain Hardening method, a fast, cost-efficient and highly accurate method for evaluating the slow crack growth resistance behaviour of HDPE. This Strain Hardening method avoids the use of detergents - that can pose an environmental hazard – and avoids the use of valuable drinking water. The term “RELY” refers to the material’s outstanding reliability, which is critical for transporting potable water, gas and other valuable liquids. It also reflects SABIC’s global reputation as a strong and reliable business partner that can ensure a long-term supply of advanced material solutions. Both new materials are classified as PE100 grades, demonstrating compliance with the highest industry standards for HDPE pressure pipe.
• SABIC® Vestolen A RELY 5924R delivers excellent low sag performance for large-diameter pipes and pressure pipes with a low standard dimension ratio (SDR). This grade has an internal pressure approval for PE 100 that complies with the EN12201 and EN1555 standards, underscoring its high quality and outstanding performance for transporting potable water, gas, sewage and other liquids.
• SABIC® Vestolen A RELY 5922R offers excellent resistance to slow crack growth propagation in high-pressure pipe applications and can therefore be used with advanced trenchless pipe installation technologies such as re-lining, horizontal directional drilling and guided boring. Its superior resistance to slow crack growth is demonstrated by results of the FNCT (>8760h) and pipe notch test (>8760h, DIN and ISO 13479). This grade also has an internal pressure approval for PE 100, meeting EN12201 and EN1555 standards.
