Skydrol vs. Foam

Can OSAAP Shadow Boards Withstand Skydrol?

What is Skydrol?

Skydrol is a hydraulic fluid used in aircrafts. In fact, the fluid is most commonly used in aerospace applications. Skydrol was the first fire-resistant hydraulic fluid on the market. Although it has many positives the fluid can be irritating to human skin and can be damaging to some materials.

In relation to Skydrol’s popularity, a common question we are asked as shadow board manufacturers is…


“Can OSAAP Foam Withstand Skydrol’s Damaging Properties?”

In short, the answer is yes, our foam can withstand the chemical properties of Skydrol. We currently have multiple customers that use our foam paired with Skydrol applications. Our foam is inert, blown-in Nitrogen, so it does not react except under very extreme conditions; the thermal limit of the foam is 500 degrees F. Skydrol leaves a thin film on the exterior of the foam. It does NOT dissolve the material.
