NORYL™ 731S FDA Compliant, NSF/ANSI 61, ACS & WRAS PPE + HIPS Blend

Good Surface Appearance, Dimensional Stability & Hydrolytic Stable

NORYL™ 731S PPE + HIPS Resin is a Non Reinforced Engineering Thermoplastic developed for applications requiring verified Drinking Water Compliance and Long Term material Stability. This Grade is certified to multiple International Standards Including NSF/ANSI 61, FDA Requirements, WRAS (UK), ACS (France), and KTW W270/WBGL (Germany), Supporting use in Potable Water Systems across Global Regions.

Material behavior of NORYL™ 731S PPE + HIPS Resin emphasizes Hydrolytic Stability, allowing reliable performance in continuous Water Contact Environments. Resistance to Moisture driven Degradation support consistent Mechanical properties over Time, making the material Suitable for components exposed to high humidity or immersion conditions.

Dimensional Control is a Key Attribute of NORYL™ 731S PPE + HIPS Resin, supported by Low Shrinkage and Low Warpage characteristics during Processing. these properties help maintain Part Geometry and Tight tolerances, which is critical in fluid handling systems and sealing interfaces where precision fit is required.

Mechanical Performance includes High Ductility and Strong Resistance to Creep, allowing NORYL™ 731S PPE + HIPS Resin to retain dimensional integrity under sustained mechanical load and long term stress. This combination of toughness and stability support durable performance in applications subject to pressure, temperature cycling, or continuous use.

Surface characteristics of NORYL™ 731S PPE + HIPS Resin Provide a Clean, Consistent Appearance in Molded Parts, supporting applications where surface quality and hygiene are important. The Non Reinforced Structure further contributes to smooth finishes and predictable processing behavior.

NORYL™ 731S PPE + HIPS Resin is defined by its UL Rating. NORYL™ 731S are UL94-HB, 1.50 mm ~ 3.00 mm Rated, supporting applications where baseline flammability performance is sufficient alongside primary water contact requirements.

Regional and Regulatory Positioning of NORYL™ 731S PPE + HIPS Resin includes dedicated support within the Asia Pacific Market while maintaining Broad International Certifications. The ROHS Compliant Status enables Integration into global supply chains, aligning potable water approval, mechanical reliability, and environmental requirements within a single material solution.
