Main Usage: Mainly used for the modification of bismaleimide resin (BMI), which can significantly reduce the application cost of BMI resin and improve its operability and processability. Improve the toughness, heat resistance, and moldability of BMI resin. Can be used for: ① Electrical insulation materials, copper-clad circuit boards, high-temperature resistant impregnating paints, insulation paint laminates, molded plastics, etc. ② Wear resistant materials, diamond grinding wheels, heavy-duty grinding wheels, brake pads, high-temperature bearing adhesives, etc. ③ Aerospace structural materials. ④ Functional materials. Adding 1-3% BBA to rubber as an anti-aging agent can greatly improve its aging resistance.
