Material: PEEK-Milled Carbon Fiber

This data is for general information only. The data has been compiled from many sources believed to be reliable, but it cannot be guaranteed.

The physical property data was compiled from material manufacturers using molded test bars, and may not represent actual performance from Entegris molded products.

The chemical contamination outgassing data was compiled from resin testing. It is not molded part data. The values are averages and are not a specification.

Minor dimensional changes begin to occur at approximately 85% of the recommended use temperature.

Because chemical resistance depends on many factors (concentration, temperature, time, etc.), you should evaluate materials under your own conditions.
