Polietherimida (PEI/Ultem)

Lograr una integridad dieléctrica excepcional y estabilidad dimensional a altas temperaturas en microelectrónica sin usar halógenos corrosivos requiere un polímero amorfo especializado, que el Ultem 1000 de SABIC ofrece a través de su matriz de poliéterimida (PEI) no reforzada y de alta viscosidad. Con una densidad de 1.27 g/cm³ y una clasificación de inflamabilidad UL 94 V-0 inherente hasta 0.4 mm, esta resina ámbar transparente es el estándar global para zócalos de prueba de alta temperatura, carcasas de telecomunicaciones y colectores médicos. Jucheng Precision, bajo los marcos ISO 9001 e IATF 16949, se especializa en el moldeo de Ultem 1000. Con más de 35 prensas avanzadas equipadas con bandas calefactoras de cerámica y controladores de temperatura de aceite, eliminamos las tensiones térmicas internas, entregando componentes ópticos impecables verificados por CMM Zeiss.

Filling ultra-thin, highly complex flow paths in high-voltage avionics and medical cassettes while maintaining 110 MPa yield strength requires an optimized high-flow super-polymer, which SABIC’s Ultem 1010 delivers through its unreinforced, high-viscosity amorphous polyetherimide matrix with improved melt rheology. Featuring an elevated glass transition temperature (Tg) of 217°C and a density of 1.27 g/cm³, this aerospace FAR 25.853 compliant grade achieves a V-0 flammability rating at 0.4mm. Jucheng Precision, under ISO 9001 and IATF 16949 frameworks, specializes in molding Ultem 1010. Utilizing 5-axis CNC-machined conformal cooling toolings, we manage its isotropic shrinkage (0.5%-0.7%) to deliver zero-defect parts verified by Zeiss CMM.

To satisfy extreme mechanical loading, dimensional stability, and continuous fire safety in advanced aerospace and electrical infrastructures, SABIC’s Ultem 2300 leverages a 30% glass fiber reinforced, amorphous polyetherimide (PEI) matrix. Featuring an elevated density of 1.51 g/cm³ and a glass transition temperature (Tg) of 217°C, this high-stiffness grade provides an exceptional tensile modulus of 9,500 MPa and inherent UL 94 V-0 flammability rating at 0.25mm. Jucheng Precision, operating under ISO 9001 and IATF 16949 frameworks, specializes in molding Ultem 2300. Utilizing 5-axis CNC-machined H13 toolings, we control its low, isotropic shrink variables (0.2%-0.4%) to eliminate warpage, verified by Zeiss CMM.

Meeting the uncompromising FAA FAR 25.853 aircraft cabin interior standards for low smoke density, low toxicity, and strict OSU 65/65 heat release limits requires an elite material, which SABIC’s Ultem 9085 delivers through its unreinforced, high-impact modified amorphous polyetherimide (PEI) blend matrix. Featuring a density of 1.34 g/cm³ and a glass transition temperature (Tg) of 186°C, this aerospace-certified polymer provides outstanding impact ductility alongside inherent self-extinguishing safety.
