Rogers RT/duroid® 5880 is a polytetrafluoroethylene (PTFE) fiberglass reinforced material optimized for high frequency circuit design. Here are some key parameters and properties of the material:

Dielectric constant (Dk): 2.20 ± 0.02

This parameter indicates that RT/duroid® 5880 has one of the lowest dielectric constants among similar materials, helping to reduce delays in signal transmission and improve circuit performance.

Dissipation Factor (Df): 0.0009 @ 10GHz

A low loss factor means the material has very little signal loss in high-frequency applications, which is critical to maintaining signal integrity.

Moisture absorption rate: as low as 0.02%

The extremely low moisture absorption rate makes RT/duroid® 5880 very suitable for use in high humidity environments, maintaining circuit reliability.


The material's electrical properties remain consistent in all directions, which is important for accurate circuit design and manufacturing.

Processing Performance:

RT/duroid® 5880 is easy to cut and form to accommodate the specific PCB shape requirements in high frequency applications.

Chemical Resistance:
