Polyetherimide (PEI) Compression Springs are lightweight and useful for applications requiring high strength, thermal stability, and long-term dimensional accuracy. These springs can achieve this in elevated temperatures.
Engineered for repeated compression cycles, PEI springs deliver dependable load retention, low creep, and outstanding dimensional stability. Their inherent flame resistance, low smoke generation, and electrical insulation properties make them an ideal choice for aerospace, electronics, semiconductor, and industrial applications where conventional metal springs may be unsuitable due to weight, corrosion, or electrical conductivity requirements.
