ULTEM™ 4211 20% Glass Reinforced PEI Resin. Added PTFE as Lubrication

Advanced Wear Resistance Formulated. reduced Coefficient of Friction

ULTEM™ 4211 PEI Resin is a High-Performance Engineering Thermoplastic reinforced with 20% Glass Fiber and PTFE Additives, designed for Applications requiring High Strength, Increased Rigidity, and reduced Friction Performance. ULTEM™ 4211 PEI Resin combines Structural Strength with Tribological Advantages, making it suitable for demanding Industrial Applications where Durability and Wear Resistance remain Critical Requirements.

The Glass Fiber Reinforcement in ULTEM™ 4211 PEI Resin provides enhanced Stiffness, Higher Modulus, and improved Dimensional Stability, allowing Components to maintain Shape and Performance under Mechanical Load and Elevated Temperatures. This Structural Performance supports reliable Integrity in both Static and Dynamic Systems.

ULTEM™ 4211 PEI Resin delivers reduced Coefficient of Friction and improved Wear Resistance through PTFE Modification, allowing smooth Operation and extended Service Life in Sliding and Contact Applications. This Tribological Capability enables ULTEM™ 4211 PEI Resin to perform efficiently in Environments requiring consistent Motion and reduced Surface Wear.

The material demonstrates excellent Strength and Stability at Elevated Temperatures, supporting Long-Term Performance in High-Heat Environments. The balanced Mechanical and Tribological Properties of ULTEM™ 4211 PEI Resin allow use in Precision Components where both Structural Reliability and Surface Performance are Essential.

ULTEM™ 4211 PEI Resin achieves UL94 V0 Rating at 1.50 mm, providing High-Level Flame Retardant Performance without added Flame Retardant Modifiers. This allows ULTEM™ 4211 PEI Resin to meet Safety Requirements in Applications requiring Flame Resistance and Material Stability.

availablein Opaque Reinforced Formulations, ULTEM™ 4211 PEI Resin is optimized for Applications where Mechanical Strength, Wear Resistance, and Long-Term Durability are prioritized. The Material Design supports consistent Performance under demanding Mechanical and Thermal Conditions.

Typical Applications for ULTEM™ 4211 PEI Resin include Wear Components, Bearings, Bushings, Electrical Parts, and Industrial Systems where Strength, Low Friction, and Dimensional Stability must be delivered together. ULTEM™ 4211 PEI Resin is also RoHS Compliant, supporting Environmentally Responsible Material Selection while delivering Advanced Structural and Tribological Performance.
