NORYL™ PPE POWDERS + CONCENTRATES 640

NORYL™ PPE POWDERS + CONCENTRATES 640 is a medium-high molecular weight polymer based on polyphenylene ether (PPE). This material is intended for use as an additive or a building block in a variety of thermoplastics and thermoplastic elastomers such as styrenic block copolymers. NORYL™ PPE POWDERS + CONCENTRATES 640 can be used to improve properties (i.e. heat distortion and creep resistance). It is hydrolytically stable and non-hydroscopic (typically less than 0.2% water uptake). The polymer is soluble in common organic solvents like toluene, chloroform, and THF. It complies with the FDA regulation 21CFR 177.2460 and EU Directive 2002/72/EC. It is available in Asia.
