Performance Under Pressure: Thermoplastic resin features impact-resistant technology

April 17, 2020

The latest addition to SABIC’s portfolio of high-performance thermoplastics for water management applications is NORYLTM resin. The new product is the first in a family of materials featuring proprietary impact-resistant technology for improved fluctuating pressure performance compared to legacy materials. The 30 percent glass-reinforced polyphenylene ether (PPE)-based grade also delivers excellent value through system cost-effectiveness.

NORYL WM330G resin delivers higher burst pressure, fluctuating pressure, and creep rupture performance to meet more aggressive qualification testing while opening new opportunities in emerging applications such as ultrasonic water meters and instant water heaters.

The new NORYL resin also enables robust injection molding with minimal effects on mechanical properties, giving customers greater processing latitude. Further, NORYL WM330G resin can help control costs compared to other high-performance glass-filled materials thanks to its lower specific gravity, which may yield more parts per unit of weight.

NORYL WM330G resin is an excellent candidate for a range of water management applications, especially those exposed to internal fluctuating pressure, such as housings for volumetric water meters, ultrasonic water meters and pump housings, as well as control valves and hydro blocks. SABIC’s water hammer testing protocol has determined that NORYL WM330G resin can deliver up to a two-fold improvement in fluctuating pressure performance compared to legacy grades. The improvements customers can achieve depend on part and tool design, testing protocol and material processing.

Wider Processing Window

NORYL WM330G resin can increase a part’s burst strength, especially when used in complex designs that prevent optimal cooling during processing. These hot spots can lead to vulnerabilities in the finished part; however, the new SABIC material helps to address this challenge and gives designers greater freedom to create more-intricate geometries.

The new NORYL grade, available globally, is being produced at the company’s facility in Bergen op Zoom, Netherlands.

SABIC’s NORYL resin portfolio offers the water management industry a wide variety of solutions to meet specific application requirements. With best-in-class hydrolytic stability and excellent high heat resistance, these materials are engineered to perform in both hot- and cold-water handling applications. This technology delivers excellent dimensional stability, low mold shrinkage, low water absorption and excellent creep resistance. With one of the lowest specific gravities of all engineering thermoplastics in its class, NORYL resin provides designers with opportunities to create lighter, more cost-efficient parts. Furthermore, the structural performance of NORYL resin can assist with easy part consolidation and assembly. WT
