Semi crystalline thermoplastic high performance polymer PEEK is characterized by the following material properties:

• High radiation resistance
  High chemical resistance
  Very good wear resistance
  High wear resistance
  Water resistance
  Because of its low water absorption, it has high dimensional stability
  high heat resistance
  Very high thermal deformation temperature
  Inherent flame resistance
  High glass transition temperature
  High melting point temperature
  Long term stability of height
  High creep resistance
  Good electrical performance

If you are looking for a high temperature polymer as a metal substitute in a component that must withstand harsh environmental conditions, these properties make VESTAKEEP a material that you choose.

VESTAKEEP ® PEEK Superior to metal

VESTAKEEP ® PEEKIt is superior to metal by improving system durability and reducing component manufacturing cost. These advantages come from corrosion resistance, abrasion resistance, high rigidity and low weight material properties, as well as multifunctional machinability.

• For example, the PEEK assembly resists corrosion caused by salts, solvents, corrosive agents, and many acids.
  High performance polymers can also reduce wear caused by slurry, particle impact and sliding friction.
  VESTAKEEP PEEK is harder and lighter than steel. Lightweight structural components help to save fuel, and allow the construction of more durable compressor parts, and provide more efficient engine designs for gears and impellers.
  The replacement of metal parts with VESTAKEEP PEEK reduces component costs due to improved durability, more effective processing methods, partial integration, and greater design freedom than machined metal components are possible.

Because of these characteristics, PEEK is developing rapidly to replace aluminum, titanium and steel in aircraft manufacturing. Bushings used in mining, pulp and paper industries are also made of high temperature polymers.

VESTAKEEP ® PEEK Better than other plastics

In all plastics, PEEK provides the best combination of inertia and heat resistance. Even after exposure to steam, ethylene oxide and gamma radiation for a long time, this high-performance polymer still retains its original properties. Very low levels of extractable compounds, degassing and contaminants make peek an excellent material for the production of MICROTEK chips from semiconductors. VESTAKEEP PEEK forming compounds are highly oxidative stable in melting, and can be used continuously at temperatures above 260 degrees centigrade.
