Description

Phenol,4,4'-(1-Methylethylidene)Bis[2,6- Dibromo-,Polymer With 2,2'-[(1-Methylethylidene)Bis(4,1-Phenyleneoxymethylene)] Bis[Oxirane] CAS NO 31942-06-0 is a high-performance brominated epoxy resin oligomer. This advanced polymer is engineered to impart exceptional flame retardancy and thermal stability to composite materials. It is a critical raw material for manufacturers in the electronics, aerospace, and construction industries requiring materials that meet stringent fire safety standards without compromising mechanical properties.

Application

• Flame Retardant for Printed Circuit Boards (PCBs): A key reactive component in epoxy resin formulations for FR-4 and other high-performance laminates, providing excellent UL-94 V-0 ratings.
• Thermoset Composites for Aerospace: Used in prepregs and composite structures where low smoke density and high flame resistance are mandatory.
• Encapsulation and Potting Compounds: Provides fire safety in protective coatings for sensitive electronic components and semiconductor devices.
• Adhesives and Coatings: Formulated into high-temperature resistant adhesives and protective coatings for industrial applications.
• Reinforced Plastic Components: Serves as a matrix resin in fiberglass-reinforced plastics (FRP) for electrical housings and automotive under-the-hood parts.
