PEEK, or Polyether Ether Ketone, is a high-performance thermoplastic polymer that has become increasingly popular in manufacturing. Known for its exceptional mechanical and thermal properties, it has applications across various sectors, from aerospace and automotive to medical and electronics. In this blog post, we’ll delve into the key characteristics of this material and explore why it has emerged as a material of choice for many demanding applications.
What is the history of PEEK, and how is it made?
Polyether ether ketone, or PEEK, is a high-performance thermoplastic polymer that has become increasingly popular across various industries. It was first developed in the late 1970s by researchers at Imperial Chemical Industries (ICI) in the United Kingdom to create a polymer that could withstand high temperatures and harsh chemical environments. Subsequently, PEEK was patented in 1978 and began commercial production in the 1980s.
The manufacturing process of PEEK involves several steps. First, raw materials, including aromatic dihalides and aromatic diones, are combined and heated to around 300-400°C. Allowing the materials to undergo a condensation polymerization reaction, forming the material’s polymer. The polymer is then cooled and solidified before being processed into the desired product form, such as sheets, rods, or injection-molded parts. It can be machined, extruded, or compression molded to create various components.
PEEK offers exceptional thermal and chemical resistance. It can withstand temperatures up to 260°C and resist most solvents, acids, and bases. Consequently, this makes it an ideal material for applications in the aerospace, automotive, medical, and oil and gas industries, among others.
IAs technology advances, PEEK’s uses and manufacturing processes will likely continue to evolve. However, the history and development of this remarkable polymer remain an essential part of its story.
