TECAPEEK® black polyetheretherketone

PEEK black

In addition to unfilled PEEK natural which is beige-brown in color, a black pigmented version of PEEK is also available. TECAPEEK black is manufactured by Ensinger and may use Victrex® PEEK 450G or Solvay Ketaspire® KT-820 polymer. It is available in rod, plate, and tube in a variety of dimensions. This black pigmented version of PEEK plastic demonstrates improved UV resistance in addition to the other typical PEEK properties which make this product an ideal material of choice for outdoor use.
