Syensqo (Solvay Specialty Polymers) Mindel® B-322 Polysulfone, Modified (PSU, Modified) (discontinued **)
Categories:	Polymer; Thermoplastic; Polysulfone (PSU)
Material Notes:	Mindel B-322 is a glass filled, modified polysulfone developed specifically for molded electrical connector applications requiring excellent dimensional stability and resistance to warpage. This material also has a high heat deflection temperature, good creep resistance, tensile and flexural strength and high rigidity. It has outstanding electrical properties, even at high frequencies and temperatures and is rated UL94 V-0 at 1/32" or 0.031"(0.8 mm) in all colors. Humidity resistance is another key feature. Mindel B-322 retains a high level of mechanical and electrical properties even at elevated temperatures, which can make it a suitable replacement for high performance thermosets. - Black: Mindel B-322 BK 1045
