General Info

Polyetheretherketone can be used at very high temperatures (about +500 °F) and exhibits extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to +500 °F and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight yellow discoloration). PEEK is self-extinguishing properties according to UL 94.

Manufacturer Trade Names

GEHR PEEK™

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
