HyboFOAM® RF（Re-enforced Fine）is closed-cell rigid foam plastic, based on PMI (polymethacrylimide) polymer, which does not contain any CFC's. HyboFOAM® RF attributes a fine and unique cell size grade (less than 0.1mm).

Based on HyboFOAM® C, keeping the premise of excellent mechanics property, HyboFOAM® RF particularly fined cell size, which is suitable for resin liquid infusion process.

The processing parameter is up to temperature of 150°C and maximum pressure up 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® RF 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, including X-Ray/CT tables, sports equipment; vehicle/high speed railway, and floating/fishing kits, etc.
