General Info
TPX™ Polymethylpentene is the lightest of all known polymers with a density of 0.83 g/cm³. It's most important property is optical transparency in both the far-infrared and visible parts of the spectrum. TPX ® also has excellent electrical insulating and chemical resistance properties, and offers a very high melting point. It is available in sheet, rod and film forms.
Key Properties
- TPX™ is optically transparent in far-infrared and visible parts of the spectrum, allowing the co-transmission of a HeNe laser alignment beam.
- Index of refraction is 1.46 and is relatively independent of wavelength.
- Loss is very low at mm-wavelengths and gradually increases until becoming unacceptable in the mid-IR at about 30 to 50 microns wavelength.
- Because of its low density, TPX ® has high acoustic efficiency (a high damping factor due to large internal losses.) It also displays exceptionally low distortion and high power handling characteristics.
Limitations

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.
Available Sizes
Sheet: .035" to 4.000" thick
Rod: .250" to 4.000" diameter
Film: .002" to .029" thick
