Ultem 9085 Flame-Smoke-Toxicity (FST) & Structural Profile
SABIC™ ULTEM™ Resin 9085 is an unreinforced amorphous Polyetherimide (PEI) blend, certified to deliver outstanding impact strength, low smoke density, and minimal toxic gas emission under international aviation standards:
| Aviation Safety Metric | Ultem 9085 Rating/Value | Cabin Engineering Compliance |
|---|---|---|
| FAA FAR難燃性 | FAR 25.853 Compliance (60-sec vertical burn) | Meets strict commercial cabin requirements, ensuring self-extinguishing behavior and preventing fire propagation inside aircraft. |
| OSU Heat Release | OSU 65 / 65 (Peak/Total Heat Release) | Limits total heat release under 65 kW/m² during combustion, highly certified for passenger cabin walls and ceilings. |
| Impact Ductility | Tensile Elongation at Break ~50% to 100% | Copolymer alloy modification provides exceptional yield toughness, preventing brittle part shattering under sudden physical impact. |
High-Compliance Process Adaptability for Ultem 9085
With its high-impact modification and amorphous stability, SABIC Ultem 9085 processes consistently inside complex mold geometries:
| Aesthetic & Structural Process | プロセス互換性と運用詳細 |
|---|---|
| Aircraft Cabin Interior Trims | Excellent. Configured with hot-runner gating to mold lightweight window frames, service trays, passenger storage latches, and interior covers. |
| Environmental Control Systems | Excellent. Outstanding dimensional stability, low toxicity outgassing, and excellent flow-thickness ratio prevent structural warping inside aircraft air-ducting manifolds. |
| Rail & Transport Enclosures | Good. Highly certified under EN 45545-2 railway fire safety requirements. Used for heavy-duty commercial bus and high-speed rail brackets. |
PEI-SABIC Ultem 9085 Tooling & Thermal Stress Management Blueprint
Molding an amorphous high-performance blend like Ultem 9085 requires strict thermal boundaries and low-stress mold setups to prevent stress-cracking:
非晶性等方収縮制御
Being an amorphous copolymer blend, Ultem 9085 exhibits low and highly uniform shrinkage (0.50% to 0.70%). We use our 5-axis CNC machines to cut precise mold cavities and balance cooling paths, ensuring zero warping and zero dimension defects on Zeiss CMM verification.
高溶融温度プロファイリング
Melting requires specialized machines with ceramic heater bands. Processing barrel temperatures are strictly managed between 340°C and 380°C (644°F to 716°F) to ensure homogeneous flow. Exceeding 390°C can result in chemical chain fracturing and polymer degradation.
加圧オイル金型温度制御
加圧オイルヒーターを使用して、金型温度を140°C〜180°C（284°F〜356°F）に維持します。高い金型温度を維持することは、成形応力を最小限に抑え、表面光沢を最適化し、複雑なスナップフィット付近のウェルドライン応力割れを完全に防ぐために重要です。.
乾燥剤予備乾燥プロトコル
PEIは非常に吸湿性が高いです。水分は外観上のスプレー、気泡、透明な光学品質の低下を引き起こします。当社は、成形前に水分レベルを0.02%未満に保つため、乾燥剤ホッパードライヤーで原料を150°C（302°F）で4時間乾燥させ、動的機械的引張結合を保護します。.
