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.   Bismaleimide Series BMI-100 CAS:13676-54-5 BMI-200 CAS:67784-74-1 HVA-2 CAS:3006-93-7   Bismaleimide series products manufactured by Yangchen Tech   Product Brand Product Name CAS Number BMI-100(Click here) N,N'-(4,4' DIPHENYLMETHANE)BISMALEIMIDE 13676-54-5 BMI-200(Click here) Phenylmethane maleimide 67784-74-1 BMI-400(Click here) Bisphenol A diphenyl ether bismaleimide 79922-55-7 BMI-500(Click here) 3,3-dimethyl-5,5-diethyl-4,4-diphenylmethanebismaleimide 105391-33-1 BMI-600(Click here) BIS(4-MALEIMIDOPHENYL)SULFONE 13102-25-5 BMI-800(Click here) 4-methyl-1,3-phenylenebismaleimide 6422-83-9     Why Choose Bismaleimide Resin?   1.High Thermal Stability: Maintains structural stability even at extremely high temperatures, resisting softening or degradation. 2.Excellent Mechanical Properties: High strength, high rigidity, and wear resistance make it suitable for structural applications. 3.Excellent Electrical Insulation: Low dielectric constant, suitable for high-frequency electronic component applications.
