The thermosetting resin matrix undergoes cross-linking during the processing process, forming a network like structure. The product is stable in scale under normal conditions and has little post molding shortening. The shape and scale of the product undergo minimal changes under long-term continuous loading, resulting in minimal creep. Its creep performance depends on factors such as the size of the load, temperature fluctuations, and the length of loading time. Under fixed load and temperature conditions, the creep deformation of thermosetting plastics after long-term loading is much smaller than that of thermoplastic plastics.
