Polyetherketoneketone

Polyetherketoneketone (PEKK) is a high-performance polymer used in a variety of applications, including medical devices. It is known for its excellent mechanical properties, high chemical resistance, and biocompatibility.

Overview

PEKK is a member of the polyaryletherketone (PAEK) family, which also includes polyetheretherketone (PEEK) and polyetherketone (PEK). These polymers are semi-crystalline and have high glass transition and melting temperatures, making them suitable for high-temperature applications.

Medical Applications

PEKK is used in a variety of medical applications due to its biocompatibility, sterilizability, and mechanical properties. It is used in orthopedics for the production of spinal, hip, and knee implants. It is also used in dentistry for the production of dental implants.

Orthopedics

In orthopedics, PEKK is used to produce spinal, hip, and knee implants. It is favored for its high strength, toughness, and fatigue resistance, as well as its compatibility with medical imaging techniques. Unlike metallic implants, PEKK implants do not interfere with X-ray or MRI imaging.

Dentistry

In dentistry, PEKK is used to produce dental implants. It is favored for its high strength and toughness, as well as its ability to be sterilized. PEKK dental implants have been shown to have excellent osseointegration properties, meaning they integrate well with the surrounding bone.

Properties

PEKK has a number of properties that make it suitable for use in medical applications. These include:

• High strength and toughness
• High chemical resistance
• High glass transition and melting temperatures
• Biocompatibility
• Sterilizability
• Compatibility with medical imaging techniques
