Victrex PEEK 450G Mechanical Strength & Thermal Limits
Victrex™ PEEK 450G is an unreinforced, medium-viscosity semi-crystalline polyetheretherketone resin, certified to deliver unmatched mechanical stiffness and continuous thermal resistance under ASTM/ISO standards:
| 엔지니어링 특성 | DAM Spec Value (ISO/ASTM) | Aerospace/Medical Advantage |
|---|---|---|
| Continuous Service Temp | 260 °C (UL 746B RTL Rating) | Maintains robust mechanical strength and prevents polymer creep under high heat, allowing for lightweighting of deep-downhole oil and aerospace brackets. |
| 굴곡 탄성률 | 4,100 MPa (ISO 178) | Delivers extremely high mechanical stiffness and anti-deflection strength, ideal for structural wear rings and rotating gears. |
| Biocompatibility & Inertness | FDA & USP Class VI Compliant | Completely chemically inert, non-toxic, and resistant to repeated autoclave steam cycles, perfectly suited for surgical trial implants and dental healing caps. |
Extreme Environment Processing Targets for Victrex 450G
With its high viscosity and semi-crystalline chemistry, Victrex PEEK 450G requires high thermal energy profiling to mold successfully:
| Critical Operating Condition | Process Suitability & Design Focus |
|---|---|
| Structural Oil Seals & Thrust Washers | Excellent. Configured with high-temperature oil controllers to mold self-lubricating automotive washers, subsea connectors, and wear-resistant bushings. |
| Biocompatible Surgical Trial Implants | Excellent. Run inside our certified ISO Class 7/8 cleanrooms to mold highly complex orthopedic target caps and dental healing screws. |
| Under-the-Hood Sensor Bodies | Excellent. Well-suited for heavy-duty connector enclosures, smart-grid isolators, and aviation cable clamps requiring low outgassing. |
Victrex PEEK 450G High-Temperature Tooling Matrix
Molding an unreinforced, high-viscosity semi-crystalline polymer like PEEK 450G requires extreme thermal boundaries to secure proper crystalline development:
고온 가압 오일 몰드 가열
To secure the proper semi-crystalline phase (giving PEEK its signature opaque beige color and stiffness), mold temperatures must be maintained continuously at 160°C–200°C (320°F to 392°F) using oil-heating controllers. Cold molds cause the melt to freeze amorphous, turning parts translucent brown and mechanically weak.
Hardened S136 Mirror-Polished Tooling
Due to the extreme clamping pressures and melt velocities of PEEK 450G, Jucheng’s tooling division uses hardened, corrosion-resistant S136 stainless steel molds. We heat-treat cavities to 52 HRC and design generous draft angles (minimum 1.5° to 2.0°) to ensure clean part release.
Ceramic Barrel Melt Management
Molding is processed between 360°C and 400°C (680°F to 752°F). Jucheng utilizes specialized, ceramic heater bands and bi-metallic barrels on our presses. Exceeding 420°C can result in chemical chain fracturing and polymer degradation.
연장 건조제 사전 건조
While PEEK absorbs minimal water, moisture causes hydrolytic splay and weld line degradation. We desiccant-dry PEEK 450G resin at 150°C (302°F) for 3–4 hours, keeping internal moisture below 0.02% to secure optimal molecular bonds.
Key Application Fields for PEEK-Victrex PEEK 450G
