Syensqo (Solvay Specialty Polymers) Mindel® B-430 Polysulfone, Modified (PSU, Modified)  (discontinued **)
Categories: Polymer; Thermoplastic; Polysulfone (PSU); Polysulfone, 30% Glass Fiber Reinforced

Material Notes: Mindel B-430 is a 30% glass reinforced thermoplastic with excellent dimensional stability, exceptional resistance to warp, good chemical resistance, and high stiffness. It was developed specifically for electrical/electronic applications requiring flame resistance, but where flame retardant systems based on polybrominated diphenyl- oxides or ethers are undesirable. The resin has a UL 94 V0 rating at 0.062" (1.57 mm) thickness, even though it does not contain polybrominated diphenyl- ethers or oxides. This material can therefore be used in areas of the world where the use of flame retardants based on polybrominated diphenylethers/ oxides may be restricted. Mindel B-430 resin's resistance to warping results from low isotropic shrinkage. Combined with high stiffness, good creep resistance and high heat distortion temperature, Mindel B-430 resin may be ideally suited for use in demanding electrical components such as relays, switches, motor starters and control housings. Mindel B-430 resin should also be considered for electrical connectors that do not have the demanding temperature requirements of surface mount technology. The material has excellent regrind stability and, unlike polyesters, retains a high level of mechanical and electrical properties even at elevated temperatures and humidities. - Black: Mindel B-430 BK 174 - Natural: Mindel B-430 NT - Grey: Mindel B-430 GY 674 - Custom Colorable
