PTFE-Filled PEI – The High-Performance Internal Lubricating Plastic for Demanding Applications
Engineered for extreme environments, our PTFE-Filled PEI is a specialty composite that masterfully combines the unparalleled thermal and mechanical properties of Polyetherimide (PEI) with the exceptional self-lubricating capabilities of Polytetrafluoroethylene (PTFE). This internal lubricant formulation delivers superior wear resistance and a consistently low coefficient of friction, creating a durable, maintenance-free solution for high-load, high-temperature moving parts where traditional lubrication fails.
Core Product Advantages:
-
Superior Wear & Friction Performance: The integrated PTFE forms a protective transfer film on sliding surfaces, drastically reducing friction (coefficients as low as 0.1-0.2) and wear, even under dry running conditions.
-
Inherited High-Temperature Excellence: Maintains outstanding dimensional stability and mechanical strength at continuous service temperatures up to 180°C, with a Heat Deflection Temperature (HDT) exceeding 200°C.
-
Inherent Safety & Stability: PEI offers inherent flame retardancy (UL94 V-0 rated), extremely low smoke emission, and excellent resistance to a wide range of chemicals, automotive fluids, and steam.
-
Engineered for Precision: Provides high dimensional stability, low creep, and excellent processability via injection molding for complex, tight-tolerance components.
Technical Performance & Reliability
Our PTFE-Filled PEI is designed to solve the core pain points of metal-on-metal wear, the failure of external lubricants, and the limitations of standard plastics in harsh conditions.
| Performance Aspect | Key Data & Benefit | Solves Customer Pain Points |
|---|---|---|
| Tribological (Wear/Friction) | • Low, Stable Friction: Dynamic coefficient of friction range of 0.1 – 0.2. • PTFE Transfer Film: Forms a self-replenishing lubricating layer for long-term performance. |
Eliminates squeak, stick-slip, and the need for grease/oil. Reduces part wear, maintenance downtime, and contamination risk. |
| Thermal & Mechanical | • High HDT: >200°C (392°F), ensuring shape integrity under heat. • High Strength & Stiffness: Maintains load-bearing capacity at elevated temperatures. |
Prevents deformation, melting, or loss of strength in hot environments (e.g., near engines, in sterilizers). |
| Safety & Durability | • Inherent Flame Retardancy: UL94 V-0 rated without additives. • Chemical Resistance: Withstands oils, fuels, alcohols, and weak acids. |
Meets stringent safety standards for aerospace, transportation, and electronics. Ensures long-term functionality in corrosive settings. |
Target Applications Across Industries
This material is the optimal choice for engineers designing durable, lightweight, and maintenance-reduced components. Here are key areas where it excels:
-
Automotive & Transportation: Bearings, bushings, seat adjuster components, door lock mechanisms, transmission seals, and low-friction guides that must endure heat and chemical exposure.
-
Industrial Machinery: Wear pads, conveyor system components, pump parts (impellers, seals), gears, and valve seats requiring dry-running capability and abrasive wear resistance.
-
Aerospace & Defense: Non-critical bearings, bushings, rail guides, and interior components that demand lightweight, flame-smoke-toxicity (FST) compliance, and high performance.
-
Medical & Food Processing: Components for surgical instruments, pharmaceutical dispensing equipment, and food machinery that require repeated steam autoclaving (sterilization), chemical resistance, and freedom from external lubricants.
-
Electrical & Consumer Durables: Connectors, coil bobbins, and moving parts in printers/copiers where dimensional stability and self-lubrication are critical.
