General introduction
PMI foam is especially suitable for vacuum infusion and RTM processes due to its optimized cell structure, where it can be used at temperature up to 180°C with pressure up to 0.7 MPa after heat treatment. It comes in different models, and each has different characteristics.
PMI foam（HF）
Application：
For radar, radomes, miniature antennas, etc., PMI foam HF is suitable for autoclaves, RTM, VARI and most composite manufacturing processes such as molding, the molding process conditions can reach 180°C/0.1MPa.
