HyboFOAM® E PMI Foam
Product Code: SDF-COR-055
HyboFOAM® E PMI Foam Fine-cell dielectric-focused series for radomes, antennas, electronics and acoustic equipment.
Why does it matter?
For PMI foam, the series is as important as density. C, E, RF and CRH should not be treated as direct equivalents because cell structure, process limits and application focus differ.
Selection criteria
- Maximum cure temperature and pressure
- Compression and shear loads
- Panel thickness and weight target
- Bonding, CNC and shaping requirements
- Dielectric or fire performance
Compare series in the PMI foam guide.
Technical Details
According to the product information, the E series may be considered for autoclave, vacuum bagging, RTM, VARTM, VARI and HP-RTM. The maximum 180°C and 0.3 MPa values depend on density; verify the final cycle against the manufacturer TDS and trials.

Frequently Asked Questions
Which applications suit HyboFOAM E?
Fine-cell dielectric-focused series for radomes, antennas, electronics and acoustic equipment.
What are the maximum process conditions?
The product information states a maximum of 180°C and 0.3 MPa, depending on density. The actual cycle must be verified for grade and part geometry.
Which density should be selected?
Compression and shear loads, panel thickness, skins, process pressure and weight target must be calculated together; selection should not be based on the lowest density alone.
