【Application】For many years, bismaleimide (BMI) has been used as a resin material to make heat-resistant structural parts and high-grade electrical insulation materials because it can withstand high temperatures and has good strength. It is used in industries such as aviation, aerospace, power equipment, electronics, computers, communications, trains, and construction. The main uses include:
1. Electrical insulation materials for motors
High-temperature resistant insulating varnishes (with solvent and solvent-free types)
Enamel wire coatings
Laminated insulating boards
Non-woven binding tapes
Mica insulating tapes
Copper-clad laminates for circuit boards
Molded plastic parts
High-temperature resistant powder coatings (F to H class) modified with epoxy resin
Cast parts
2. Matrix resins for advanced composite materials
High-temperature structural parts used in aircraft and spacecraft
High-temperature carbon fiber parts
Printed circuit boards
Other functional materials
3. Engineering plastics modification
Used as reinforcing agents or crosslinking agents for various common plastics, such as PP, PA, ABS, APC, PVC, PBT, EPDM, PMMA, etc.
Also used as a new type of rubber vulcanizing agent (a substance that makes rubber hard and strong)
4. Wear-resistant materials
Diamond grinding wheels
Heavy-duty grinding wheels
Brake pads
High-temperature resistant bearing adhesives
Magnetic materials
5. Other areas
Oil-free lubricating parts in fertilizer production (ammonia synthesis) equipment
Dynamic and static sealing materials
It is also used in many other high-tech fields.
