TECAPEEK RP natural

Reprocessed PEEK

TECAPEEK RP natural is the more environmentally friendly alternative to our conventional material TECAPEEK natural. TECAPEEK RP natural consists of recycled PEEK and therefore has an optimised CO2 footprint compared to the fossil material. We are not talking about peek recycling here, but about the reprocessing of PEEK by-products from customer take-backs under the Ensinger Shapes return program.

TECAPEEK RP natural is comparable to the fossil based version and is characterised by outstanding mechanical properties, especially at high temperatures. The reprocessed PEEK material is also known for its chemical resistance and application temperatures of up to 260 °C. Thanks to its excellent dimensional stability and high creep resistance, it is particularly suitable for demanding machined parts.
Ensinger engages in PEEK reprocessing of TECAPEEK RP natural in the form of PEEK tubes, PEEK plates and PEEK rods made from reprocessed plastic material.

TECAPEEK RP natural is part of Ensinger's "Reuse for Tomorrow" solutions, which includes carefully developed products that contribute significantly to environmental protection through their reduced CO2 footprint.
