PEEK (Polyether ether ketone) is a high-performance thermoplastic known for its exceptional thermal, mechanical, and chemical properties. When used as insulation for wires and cables, PEEK ensures unparalleled durability and safety, making it the top choice for industries ranging from aerospace to healthcare.
Operating Temperature: -60°C to +260°C
Operating Voltage: 600V
Insulation: PEEK
Approval: /
Tensile Strength:
PEEK exhibits high tensile strength, typically ranging from 90 MPa to 160 MPa (13,000 psi to 23,000 psi), depending on the grade and processing conditions.
The high tensile strength of PEEK makes it capable of withstanding significant pulling forces without deformation or failure.
Flexural Strength:
PEEK has excellent flexural strength, ranging from 150 MPa to 230 MPa (22,000 psi to 33,000 psi), allowing it to resist bending and deformation under load.
This property is crucial for maintaining the structural integrity of insulated wires and cables, especially during installation and operation.
Impact Resistance:
PEEK exhibits good impact resistance, absorbing energy and resisting fracture when subjected to sudden or repeated impacts.
This property is particularly important in applications where cables may be exposed to mechanical shocks or vibrations.
Compressive Strength:
PEEK has a high compressive strength, typically ranging from 220 MPa to 360 MPa (32,000 psi to 52,000 psi), enabling it to withstand compressive forces without significant deformation.
This property is beneficial in applications where cables may be subjected to compressive loads or pressure.
Fatigue Resistance:
PEEK demonstrates excellent fatigue resistance, maintaining its mechanical properties even after repeated cyclic loading.
This property ensures long-term reliability and durability of PEEK insulated wires and cables under dynamic operating conditions.
Thermal Stability:
PEEK is known for its exceptional thermal stability, retaining its dimensional integrity over a broad temperature range.
It can withstand continuous operating temperatures up to approximately 250°C (482°F) without significant deformation or softening.
Low Coefficient of Thermal Expansion (CTE):
PEEK has a relatively low coefficient of thermal expansion, typically around 30-40 ppm/°C.
This low CTE means that PEEK insulated wires and cables expand and contract minimally with changes in temperature, reducing the risk of dimensional changes and material stress.
Resistance to Moisture Absorption:
PEEK exhibits low moisture absorption properties, absorbing less than 0.5% of water by weight even under humid conditions.
This low moisture absorption helps maintain dimensional stability in environments where exposure to moisture could otherwise cause swelling or dimensional changes.
Chemical Resistance:
PEEK is highly resistant to a wide range of chemicals, including acids, bases, solvents, and fuels.
This chemical resistance contributes to the dimensional stability of PEEK insulated wires and cables by protecting them from chemical-induced degradation or swelling.
Mechanical Strength Retention:
Despite changes in temperature or environmental conditions, PEEK retains its mechanical properties, including tensile strength, flexural strength, and stiffness.
This consistent mechanical strength ensures that PEEK cables maintain their structural integrity and performance over time.
Aerospace and Defense: PEEK insulated wires and cables are used in aerospace applications where dimensional stability is critical for maintaining performance in extreme temperature and pressure conditions.
Automotive Industry: PEEK cables find applications in automotive systems requiring precision and reliability under varying temperatures and mechanical stress.
Industrial Equipment: PEEK insulated wires are employed in industrial machinery and equipment where dimensional stability ensures consistent performance in harsh environments.
Precision and Consistency: PEEK's dimensional stability allows for precise manufacturing and consistent performance in critical applications.
Reliability in Harsh Environments: PEEK cables maintain their shape and size even when exposed to challenging environmental conditions, ensuring long-term reliability and durability.
Reduced Risk of Material Stress: By minimizing dimensional changes with temperature fluctuations, PEEK reduces the risk of material stress, warping, or deformation.
