描述
ULTEM Resin SF2350 is a 30% 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 engineered for demanding thin-wall applications requiring exceptional flow and precision. The 30% glass fiber reinforcement provides significantly increased stiffness and strength compared to lower-reinforced grades, while the super high flow characteristics enable the molding of complex, miniature components with thin sections. An integrated easy-release characteristic supports smoother demolding and reduces the risk of part distortion.
With a glass transition temperature of 217°C, SF2350 delivers excellent thermal stability, high stiffness (tensile modulus 11,600 MPa), and dimensional precision. UL94 V-0 flame retardancy is achieved from 1.50mm to 1.60mm. Available in transparent amber and opaque color options, the material is ECO conforming, RoHS compliant, and ISCC+ certified renewable bio-based options are available.

Critical Processing Warnings:
-
Drying: ULTEM SF2350 is hygroscopic and must be dried to <0.02% moisture before processing.
-
Super High Flow: This grade offers exceptional flow characteristics (MVR 30 cm³/10min) for thin-wall and complex geometry molding.
-
Easy Release: Integrated easy-release characteristic supports smoother demolding and reduces risk of part distortion.
-
Melt Temperature: Recommended melt temperature range is 350-400°C. Avoid excessive residence times to prevent thermal degradation.
-
Mold Temperature: Higher mold temperatures (135-165°C) improve flow and reduce residual stress.
-
Thin-Wall Molding: Capable of molding thin sections with uniform material distribution.
-
Regrind: Regrind can be used up to 20-25% with virgin material, provided it is clean and properly dried.
