SABIC NORYL™ Resin PKN4752 Polyphenylene Ether + PS (PPE+PS) (Americas)
Categories: Polymer; Thermoplastic; Polystyrene (PS); Polystyrene + Polyphenylene Ether, Unreinforced

Material Notes: NORYL PKN4752 resin is a non-reinforced, translucent, high heat blend of polyphenylene ether (PPE) + high impact polystyrene (HIPS). This extrudable and injection moldable grade exhibits high heat resistance, dimensional stability, and appears translucent with a yellow tint in the natural color. NORYL PKN4752 resin is an excellent candidate for high performance packaging in food, electronics, and healthcare. *See NORYL PKN4752F resin for FDA food compliant version.

Features: Hydrolytic Stability,Low Creep Sensitivity,High Heat Resistance,Translucent,Low Warpage
