描述
ULTEM Resin SF2250 is a 20% glass fiber reinforced, super high flow polyetherimide (PEI) resin manufactured by SABIC. As an authorized distributor and trader, we supply genuine SABIC materials with full traceability.
This grade is specifically engineered for demanding thin-wall applications requiring exceptional flow and precision. The super high flow characteristics enable the molding of complex, miniature components with thin walls down to 0.2 mm using conventional injection molding equipment. The SF2250EPR variant additionally features internal mold release for improved demolding and processing efficiency.
With a glass transition temperature of 217°C and UL94 V-0 flame retardancy, SF2250 delivers excellent thermal stability, high strength, and dimensional precision. The material is widely adopted in semiconductor burn-in test sockets (BiTS) used for stress-testing integrated circuit chips, as well as connectors and other electronic components requiring miniaturization.
