1,4-Phenylenebismaleimide

Description:

1,4-Phenylenebismaleimide (CAS 3278-31-7) is a chemical compound characterized by its structure, which features two maleimide groups attached to a phenylene backbone. This compound is typically a white to light yellow solid at room temperature and is known for its excellent thermal stability and mechanical properties, making it suitable for high-performance applications. It is commonly used as a curing agent in epoxy resins and as a modifier in thermosetting plastics, enhancing their heat resistance and chemical durability. Additionally, 1,4-Phenylenebismaleimide exhibits good adhesion properties and is often utilized in the production of composite materials, particularly in the aerospace and automotive industries. Its reactivity allows it to participate in various polymerization processes, contributing to the formation of cross-linked networks. Safety considerations include handling it with care, as it may cause irritation upon contact with skin or eyes, and appropriate personal protective equipment should be used during handling.
