Bismaleimide resin (BMI Resin or Bismaleimide) is a high-performance thermosetting polymer. Compared to conventional epoxy resins, it offers superior high-temperature resistance, mechanical strength, and electrical insulation properties, making it widely used in aerospace, automotive electronics, advanced composites, and other fields.

BMI Resin's molecular structure contains maleimide groups, which form a highly cross-linked network through addition or free radical polymerization. This ensures stable performance in environments with continuous operating temperatures of 250–300°C, maintaining strength and reliability.
