General Info
PolyTetraFluoroEthylene is a fluorocarbon-based polymer and is commonly abbreviated PTFE. While the most famous brand of PTFE is manufactured only by DuPont, several other manufacturers make their own brands of PTFE which can often be used as substitute material. PTFE has outstanding chemical resistance, a wide operating temperature range from cryogenic to 500F, resistance to weathering, high impact strength, low friction, electrical and thermal insulation, and self-lubricating properties. 25% Glass filled PTFE has improved dimensional stability with a lower coefficient of linear thermal expansion and higher deformation under load.

Manufacturer Trade Names
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.
