[0002] High-rigidity foam filler is a porous polymer material made through a special foaming process. Before curing, it is a flowable liquid or paste that can fully fill complex cavities and gaps. After curing, it forms a closed-cell foam structure that combines high rigidity, lightweight and excellent strength. This material can effectively improve the overall rigidity and stability of the structure, and has good sound insulation, shock absorption and cushioning performance. Due to its convenient operation, dense filling and outstanding mechanical properties, it is widely used in automobile manufacturing, aerospace, building materials and precision instrument packaging and other fields. It is a key engineering material for achieving lightweight design and enhancing structural strength.
