Amodel® HFFR-4133 is a 33% glass-reinforced, halogen-free, flame retardant polyphthalamide (PPA) resin which offers enhanced processing capabilities for electrical and electronic applications. This resin is rated V-0 by Underwriters Laboratories using the UL94 test and is hot-water moldable. It has high flow and a wide processing window and offers good surface appearance, especially for larger electrical components. This grade can withstand the demanding infrared reflow soldering process typically used in the electronics industry. It is well suited for connectors and other electrical devices requiring surface mount technology (SMT).
