Celanex® 3216 EA3583 White

Technical Datasheet | Supplied by Celanese
Celanex® 3216 EA3583 White is a crystalline, non-exuding, flame-retardant polybutylene terephthalate (PBT) reinforced with 15 % glass fiber. Exhibits a good balance of mechanical properties & processability, high heat-distortion temperature, high thermal stability, excellent electrical insulation resistance, high strength, rigidity, paintability, rapid crystallization & fast cycle time, low creep even at high temperatures, very good low friction, wear- & weathering resistance, no environmental stress cracking, and good electrical properties. Offers good dimensional stability, low moisture absorption, along with resistance to a wide range of chemicals, solvents, oils and greases. Can be processed using injection molding. Recommended for electrical connectors which require UL approved 50% regrind use capability, brush holders, ignition components, motor bells & end caps, multipin edge-card connectors, power- or signal connectors, relay cases & covers, sensor housings, sockets, surface mount technology connectors, and terminal boards. It is UL & CSA approved as V-0 at 1/32 inch and 5V at 1/8 inch, and complies with the REACH and RoHS regulations.
