Stanyl® HFX31S B-MB

Chemical Family: Polyamides

Stanyl® HFX31S B-MB is a high-performance polyamide 46 used for applications in automotive, E&E, gears, and outdoor power equipment. It is a high-performance polyamide that provides unmatched performance and value for demanding applications in which superior heat resistance, design stiffness, wear and friction, and process flow qualities are required. Since it retains its mechanical properties at high temperatures up to 220 °C, this makes it ideal for extremely high-performance applications, where it outperforms PPA, PA6T, PA9T, and often PPS and LCP. A suitable processing technology for the product is injection molding.
