6 FAQs about [Peek storage modulus]
What is the storage modulus of PEEK samples?
The storage modulus of PEEK samples is equal to 2000–2800 MPa in the temperature range 30–110 °C, falling drastically in proximity of the glass transition temperature (140 °C) and stabilizing above 100 MPa for temperatures higher than 200 °C.
At what temperature does the storage modulus of PEEK stabilize?
The storage modulus of PEEK samples falls drastically in proximity of the glass transition temperature (140 °C) and stabilizes above 100 MPa for temperatures higher than 200 °C.
What is the storage modulus of a 3D printed Peek?
The 3D printed PEEK maintains a stable storage modulus, starting at 2.3 GPa at 25 °C and ending at 2.0 GPa at 150 °C which is the start of the glass transition temperature ( Tg ). Beyond Tg, the material consequently transitioned from a stiff to elastic state, which is indicated by the significant drop of the storage modulus (E').
What is the loss modulus of a PEEK sample?
The loss modulus of PEEK specimens results equal to 20–40 MPa in the temperature range 30–100 °C, increases above 150 MPa in the glass transition region (110–170 °C) and levels off at 10–20 MPa for higher temperatures.
What is Peek used for?
PEEK is a strong and stif thermoplastic material that is often used in applications where performance at elevated temperatures is required. PEEK has outstanding chemical resistance as well as resistance to steam and hot water. PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties.
