Polymethacrylimide (PMI) foam is a crosslinked rigid structural foam with 100% closed cell structure, its uniformly crosslinked pore wall structure can give it outstanding structural stability and excellent Mechanical pr...
The methyl group is arranged on the same side of the main chain of the molecule as isotactic polypropylene. If the methyl groups are disorderly arranged on both sides of the main chain of the molecule, it is called atact...
PMI (polymethacrylimide) foam is the latest material in the development of polymer foam core materials. It has low density, excellent high temperature resistance, low dielectric constant and dielectric loss, good fatigue...
NASA and European Airbus have recently proposed a foam-filled reinforced strip structure based on the use of sandwich structures and reinforced strip structures for many years, maximizing structural design and manufactur...
The core materials for composite sandwich structures are: rigid foam, PMI foam, honeycomb and balsa wood. Rigid foams mainly include polyvinyl chloride (PVC), polyurethane (PU), polyetherimide (PEI) and acrylonitrile-sty...
