Adopting this new resin helps customers proactively prepare for future restrictions on butadiene in drinking water. At the same time, it offers improved properties compared to the incumbent NORYL 713S resin.
New NORYL WM300G resin is formulated without conventional impact modifiers that can degrade under exposure to high molding temperatures and long barrel residence times. The butadiene molecules that are released can leach into drinking water, potentially affecting human health.
Instead, the new product uses pioneering impact chemistry that improves processing stability to avoid the release of butadiene, while ensuring high impact performance and high strength to meet burst pressure test requirements in shower heads, faucets, valves, water meter internal components and other parts. NORYL WM300G resin provides 20 to 30 percent higher burst strength (80-81 Mpa) compared to its legacy counterpart, NORYL 713S resin, at 64-65 Mpa.
The new product also surpasses the incumbent NORYL resin in fatigue performance and flexural and tensile modulus. It features an attractive surface appearance, low moisture absorption and good dimensional stability. It is food contact compliant and is formulated without bisphenol A (BPA) or intentionally added per- and polyfluoroalkyl substances (PFAS). It is currently awaiting global drinking water certifications.
NORYL WM300G resin is a non-reinforced, impact-modified blend of polyphenylene ether (PPE) and polystyrene (PS). In addition to injection molding, it can be extruded to produce pipes and profiles.
SABIC provides technical support to NORYL resin customers via the Water Management Center of Excellence in the Netherlands. This specialized facility offers technical services including predictive engineering, mold flow analysis, 3D simulation, testing and validation. The center is accessible to customers worldwide via a digital interface that enables remote engagement with experts.
