Description
PEEK Sheet is a high-performance engineering plastic known for its exceptional mechanical properties and temperature resistance. Ideal for demanding applications in aerospace and medical fields.
Material Properties
PEEK, or Polyetheretherketone, is a semi-crystalline thermoplastic that exhibits remarkable mechanical strength and temperature stability. It can withstand temperatures ranging from -50°C to +250°C and has a melting point of approximately 343°C, making it suitable for high-temperature applications.
Advantages of PEEK Sheet
This material offers excellent chemical resistance, low flammability, and good radiation resistance. Its high tensile strength, ranging from 90 to 100 MPa, and its biocompatibility make it an ideal choice for various applications, including food contact.
Applications of PEEK Sheet
PEEK Sheet is widely used in demanding environments such as seals, backup rings, valves, and components for the aerospace and medical industries. It is also suitable for applications in automotive and chemical processing, as well as in the oil and gas sector.
Machining and Bonding
While PEEK can be machined effectively, it requires an annealing process to relieve stress before cutting. Bonding PEEK can be challenging due to its low surface energy, which may necessitate surface roughening to improve adhesive strength.
