Use | Use 2,2 '-diallyl bisphenol A, commonly used abbreviation DBA, is mainly used for the modification of Bismaleimide resin (BMI), which can greatly reduce the application cost of BMI Resin, improve the operability and manufacturability of BMI Resin. The toughness, heat resistance and molding property of BMI Resin are improved. Can be used for: (1) electrical chemical book insulation material, copper clad circuit board, high temperature resistant impregnating varnish, insulating lacquer laminate, molded plastic, etc. Wear-resistant materials, diamond grinding wheel, heavy load grinding wheel, brake pads, high temperature bearing adhesive, etc. (3) aerospace structural materials. (4) functional materials. The anti-aging agent for rubber, adding 1-3% BBA in rubber, can greatly improve the aging resistance of rubber. |
