Material: PEI Ultem

Manufactured in PEI Ultem:

High Mechanical Strength: PEI Ultem provides exceptional tensile and compressive strength, ensuring that the nuts can handle significant loads and stresses without deformation, making them suitable for high-stress applications.

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

Chemical Resistance: The material is highly resistant to a wide range of chemicals, including acids, bases, and solvents. This property ensures that the nuts maintain their integrity and performance in corrosive environments.

Flame Retardancy: PEI Ultem’s inherent flame-retardant properties enhance safety in applications where fire resistance is crucial, such as in electrical and aerospace components.

Electrical Insulation: PEI Ultem is an excellent electrical insulator, making these nuts suitable for use in electronic and electrical assemblies where preventing electrical conductivity is essential.

Low Outgassing: The low outgassing characteristic of PEI Ultem is critical for maintaining clean environments in applications like semiconductor manufacturing and cleanroom settings, where contamination must be minimised.

Corrosion Resistance: Unlike metal alternatives, PEI Ultem hexagon nuts do not corrode, making them ideal for use in humid or wet environments where metal components might degrade over time.

Biocompatibility: PEI Ultem’s biocompatibility allows these nuts to be used in medical and healthcare applications where compatibility with biological systems is a requirement.

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

Precision and Consistency: PEI Ultem allows for precise moulding and consistent performance, ensuring a high-quality fit and reliable operation in critical assemblies.
