HyboFOAM® A
Introduction
HyboFOAM® A is a closed-cell rigid foam based on polymethacrylimide (PMI), which contains no halogen at all. The cell size is coarse and uniform.
After different heat treatment processes, it can be divided into conventional and HT series, and the HT series has better high-temperature creep resistance.
Structural Foam For Aircraft
HyboFOAM® A manufacturing meets the material specification CMS-CP-403 requirements of COMAC and is mainly used for high-grade composite material components, such as aircraft, aerospace/launch vehicles, drones, etc.

Processing and Production
HyboFOAM® A can withstand a medium temperature curing process with a maximum temperature of 180 ℃ and a maximum pressure of 0.7 MPa, depending on the density. Suitable for curing methods such as autoclave, vacuum bag, RTM, VARTM, VARI, HP-RTM, etc.
Due to its excellent surface resin absorption, engineers can find a perfect balance between peel strength and lightweight requirements.
Thermoforming and Shaping
To meet different dimension parts and geometry, it is very easy to shape HyboFOAM® A by thermo-shaping, bonding by various adhesive, and common CNC machine.
HYBO can also directly provide high-precision preformed or ready to use foam core materials with complex or simple geometric shapes.
