Stanyl® HFX31S

Chemical Family: Polyamides

Stanyl® HFX31S 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. This high-performance polyamide 46 is used for applications in automotive, E&E, gears, and outdoor power equipment. 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. Special features include good or high flow and being phosphorous-free.

Reflow Connectors Application Data: Stanyl® PA46 and ForTii® PA4T allow for reliable solutions due to their high melting temperatures (allowing the use of high reflow temperatures) and high mechanical performance (implying a reduced reject rate during pin assembly + meeting mechanical specification also after reflow soldering); ForTii® PA4T increases the reliability even due to a high dimensional stability, a low and isotropic CLTE leading to high co-planarity and low warpage after soldering; Stanyl® PA46 and ForTii® PA4T allow for cost effective solutions due to their ease of processability and flowability (enabling thin wall designs)
