Why can N,N-4,4-diphenylmethyene bismaleimide be used in the production of electrical insulation materials?
Feb 27, 2024
As a bismaleimide resin matrix, N,N-4,4-diphenylmethyene bismaleimide BMImanufactured by Yangchen Tech has the following properties: heat resistance, oxidation resistance, and radiation resistance. Widely used in electric power, aviation, aerospace, computers, communications, automobiles, railways, construction and other industrial fields.
The reason why N,N-4,4-diphenylmethylene bismaleimide (BMI) can be used to produce electrical insulation materials is mainly due to its unique physical and chemical properties.
First, BMI has excellent insulation properties. The maleimide group and benzene ring structure in its molecular structure make it have good electrical insulation and can effectively prevent current from passing through the material, thus ensuring the normal operation of electrical equipment and systems.
Secondly, BMI has excellent heat resistance. It has a high melting point, usually between 150 and 158°C, and can maintain stable performance at high temperatures. This allows BMI to withstand high-temperature environments in electrical insulation materials and not easily deform or melt, thereby maintaining its insulating properties.
In addition, BMI also has good chemical stability. Insoluble in water and ethanol, easily soluble in acetone, dimethylformamide and other organic solvents, and not susceptible to chemical corrosion. This allows BMI to resist chemical attack from electrically insulating materials, maintaining its performance and stability.
N,N-4,4-diphenylmethylene bismaleimide (BMI) can be used in the production of electrical insulation materials due to its excellent insulation properties, heat resistance and chemical stability . These characteristics make BMI an ideal choice in the field of electrical insulation materials, ensuring the safe and stable operation of electrical equipment and systems.
