Classification of Polyimide
Aromatic polyimide is an important material in microelectronics industry. According to chemical composition, polyimide can be divided into aliphatic polyimide and aromatic polyimide. According to processing characteristics, polyimide can be divided into thermoplastic and thermosetting. Polyimide with aromatic structure has the most stable thermal properties, and it is a polyimide material commonly used in microelectronics industry.
