Does PEEK absorb water?

Moisture absorption (also known as water absorption) is the capacity of a material to absorb moisture from its environment. … Plastics with very low water absorption are polymers such as PEEK,PPS, PSU, PPSU, PEI, PVDF, PET, PPE, PP and PE. Furthermore, low water absorption is exhibited by POM, PA12, PC and ABS.

What is PEEK PTFE?

PTFE filled PEEK is a material that exhibits extremely good sliding and wear properties. Ensinger manufactures this material under the trade name TECAPEEK TF10 blue, using Victrex PEEK 450G polymer. This PEEK product is often used in the food industry due to its good mechanical, thermal and chemical properties.

Is PEEK a polycarbonate?

Is Pom vs PTFE?

PTFE has the lowest friction constant of any plastic material. It is not a thermoplastic but it can be extruded. … Acetal or polyoxymethylene (POM) is a semi-crystalline, non-amorphous type of thermoplastic. Delrin, which is the DuPont brand name for Acetal, is a homopolymer.

How strong is PEEK?

Its Young’s modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK has a glass transition temperature of around 143 C (289 F) and melts around 343 C (662 F).

Is PEEK machinable?

PEEK is a machinable thermoplastic, but critical steps must be taken before, during, and after machining to deliver the best end product. Annealing: Annealing is a process performed on PEEK rods to relieve stress and reduce the chances of stresses and surface cracks in the PEEK material during machining.

Is PEEK fire retardant?

For this reason, almost all polymers need additives that can be called Flame Retardant. Super polymers like ULTEM AM9085F and PEEK have this property intrinsically with no need of additives. Both materials have the UL 94-V0 certification, the best class for the self-extinguishing materials.

Does PEEK degrade in the body?

At 250C, mechanical degradation was detected after 16 weeks of thermal aging, whereas aging at 310C produced rapid degradation [62]. Based on these studies, it is clear that thermal degradation is not a concern during clinical use of PEEK biomaterials around 37C.

Why is PEEK used in implants?

PEEK is widely used for spinal implants as the durability and resistance of PEEK implants resemble the characteristics of bone. … They help the movement of the spine and they withstand the load of body without breaking. It is also used in other orthopedic surgeries such as hip replacements because of their high strength.

Does PEEK conduct electricity?

PEEK ELS CF 30 is a 30% conductive carbon fibre filled PEEK material, produced and marketed by Ensinger under the brand name TECAPEEK ELS CF 30 black. This electrically conductive plastic provides a very high stiffness and creep resistance through the conductive carbon fibres.

What is special about PEEK?

Polyetheretherketone (PEEK) is a semi-crystalline, high-performance engineering thermoplastic. This rigid opaque (grey) material offers a unique combination of mechanical properties, resistance to chemicals, wear, fatigue and creep as well as exceptionally high temperature resistance, up to 260C (480F).

Is PEEK plastic food grade?
