NORYL GTX918A resin is a non-reinforced alloy of Polyphenylene Ether (PPE) + Polyamide (PA). This injection moldable grade exhibits high heat resistance, excellent chemical resistance, high melt flow, and added mold release. NORYL GTX918A resin may be an excellent candidate for automotive under-the-hood and electrical applications requiring the retention of properties while under thermal load.
