PEI Ultem Flat Washers offer exceptional performance and durability for a wide range of applications. Crafted from PEI Ultem, a high-performance thermoplastic known for its outstanding mechanical strength, thermal stability, and chemical resistance, these washers provide reliable support and spacing in demanding environments. Their flat design ensures a consistent load distribution and helps to prevent damage to surfaces, while their excellent resistance to high temperatures and corrosive chemicals makes them ideal for use in aerospace, automotive, electronics, and industrial applications.

Material: PEI Ultem

Manufactured in PEI Ultem:

High Mechanical Strength: PEI Ultem’s excellent tensile and compressive strength ensure that the washers can handle significant loads and stresses without deformation or failure, providing robust support in critical applications.

Thermal Stability: PEI Ultem maintains its mechanical properties at high temperatures, often up to 200°C (392°F). This makes the washers suitable for use in environments with elevated temperatures, such as in aerospace and automotive applications.

Chemical Resistance: PEI Ultem is resistant to a wide range of chemicals, including acids, bases, and solvents. This property makes the washers ideal for use in harsh chemical environments, ensuring long-term performance without degradation.

Flame Retardancy: The inherent flame-retardant properties of PEI Ultem provide added safety in applications where fire resistance is critical, such as in electronics and aerospace industries.

Electrical Insulation: PEI Ultem serves as an excellent electrical insulator, making these washers suitable for use in electronic and electrical assemblies where preventing conductivity is important.Low Outgassing: PEI Ultem has low outgassing properties, which is essential for maintaining clean environments in sensitive applications like semiconductor manufacturing and cleanroom settings.

Corrosion Resistance: Unlike metal washers, PEI Ultem washers do not corrode, making them ideal for use in moist or humid environments. This ensures durability and reliability over time.

Biocompatibility: PEI Ultem is biocompatible, making these washers suitable for use in medical and healthcare applications where compatibility with biological systems is required.

Lightweight: Despite their strength, PEI Ultem washers are lightweight, which benefits applications where weight reduction is important, such as in aerospace and automotive industries.

Precision and Consistency: The material allows for precise molding, ensuring high-quality and consistent performance of the washers, which is crucial for high-accuracy applications and assemblies.
