Ultem™ 2200 (20% Glass Filled): Superior Structural Rigidity
Ultem 2200 is 20 percent glass fiber reinforced Ultem (PEI) supplied as extruded rods and plates. Designed for machined parts that require higher stiffness, reduced creep, and improved dimensional stability compared to Ultem 2100 and unfilled Ultem.
What Ultem GF20 offers
Performance characteristics that make Ultem GF20 suitable for structural applications requiring higher loads and dimensional stability.
Higher stiffness than GF10
The increased glass fiber content improves rigidity, making GF20 suitable for parts under higher mechanical loads.
Reduced creep under sustained stress
Better resistance to deformation helps machined components hold their shape and tolerances over time.
Maintains Ultem’s high-temperature capability
Performs reliably in continuous high-temperature environments without losing structural integrity.
Strong dimensional stability
Lower deformation under load supports consistent performance in demanding operating conditions.
Suitable for structural parts that still need insulation
Balances mechanical strength with the thermal and electrical performance Ultem is chosen for.
