HyboFOAM® CRH（Railway High-Speed）is closed-cell rigid foam plastic, based on PMI (polymethacrylimide) polymer, which does not contain any CFC's. HyboFOAM® CRH attributes a fine and unique cell size grade (0.1 to 0.3mm), with particular fireproof property.

The processing parameter is up to temperature of 150°C and maximum pressureup to 0.5 MPa.Structural components can be manufactured by the following cure methods; Autoclave, Vacuum bagged, RTM, VARTM, VARI，HP-RTM and others. Due to superb resin absorption property, engineer will seek an excellent balance between peel-off strength and light-weight requirement. To meet different dimension parts and geometry, it is very easy to shape HyboFOAM® CRH by thermo-shaping, bonding by various adhesive, and common CNC machine.

The application of HyboFOAM® RF is pretty wide. Basically, it is suitable for most of sandwich structure composites parts in vehicle/high speed railway, such as interiors and wall panel, as well as the ones require fireproof or fire volatile matters.
