General Info

TECAPEEK® ST is a multipurpose semi-crystalline material from the polyaryletherketone family based on PEKEKK that features improved mechanical properties at higher temperatures. The benefits of TECAPEEK® ST compared to standard TECAPEEK® are that of a higher heat distortion temperature (HDT), better strength and stiffness of machined components and a higher flexural strength combined with a higher glass transition point.

Manufacturer Trade Names

TECAPEEK® ST

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.
