ULTEM™ 4001 PTFE Filled Standard PEI Resin. Internal Lubricant Feature

Low Friction Performance and High Wear Resistance for Moving Components

ULTEM™ 4001 PEI Resin is a High-Performance Engineering Thermoplastic formulated with PTFE Additives, designed for applications requiring Low Friction, Wear Resistance, and reliable Mechanical Performance without Glass Reinforcement. ULTEM™ 4001 PEI Resin provides a balanced Solution for Tribological Applications where Smooth Motion and Long-Term Durability remain Critical Requirements.

The PTFE Modification in ULTEM™ 4001 PEI Resin enables reduced Coefficient of Friction and improved Wear Resistance, allowing components to perform efficiently in Sliding and Dynamic Contact Systems. This capability makes ULTEM™ 4001 PEI Resin suitable for Applications requiring Noise Reduction, Smooth Operation, and consistent Surface Interaction Performance.

ULTEM™ 4001 PEI Resin maintains High Strength, excellent Dimensional Stability, and strong Resistance to Deformation, even without Fiber Reinforcement. The Non-Reinforced Structure of ULTEM™ 4001 PEI Resin supports Better Surface Finish and reduced Abrasion on Mating Components, improving overall System Longevity.

Good Processability and consistent Flow Characteristics allow ULTEM™ 4001 PEI Resin to enable efficient Manufacturing of Complex Geometries while maintaining reliable Mechanical and Tribological Performance. This supports Production Efficiency in Precision and High-Volume Applications.

ULTEM™ 4001 PEI Resin achieves UL94 V0 Ratedfrom 0.38 mm to 3.00 mm, providing High-Level Flame Retardant Performance without Additional Flame Retardant Modifiers. This ensures Safe and Stable Performance in Applications requiring Flame Resistance and Material Reliability.

Stable Mechanical and Tribological Performance across a Wide Temperature Range allow ULTEM™ 4001 PEI Resin to perform reliably in demanding Operational Environments. The material maintains Functional Stability under varying Thermal and Mechanical Conditions, supporting Consistent Application Performance.

ULTEM™ 4001 PEI Resin is available in Opaque Colors, optimized for Performance-Focused Applications where Wear Resistance, Low Friction, and Surface Durability are Essential Characteristics.

Typical Applications for ULTEM™ 4001 PEI Resin include Bearings, Bushings, Sliding Components, Wear Parts, and Industrial Systems where reduced Friction, High Wear Resistance, and Dimensional Stability must be delivered together. ULTEM™ 4001 PEI Resin is also RoHS Compliant, supporting Environmentally Responsible Material Selection while delivering reliable Tribological Performance without Reinforcement.
