A, the chemical properties of polyim為裡ide film
Polyimide chemical proper少問ties are stable. Polyimide do紅船es not need to 來輛add flame retardant to stop burning. Th長得e general polyimide are resistant t秒農o chemical solvent器匠s such as hydrocarbons, esters, eth裡風ers, alcohols and flurochlorane. They店電 are also resistant to 問能weak acids but are not recommend機房ed for use in stronger習愛 alkaline and inorganic acid enviro如嗎nments. Some po畫請lyimides such as CP1 不子and CORIN XLS are soluble i內聽n solvents, a property that helps deve愛讀lop their application 厭業in spraying and low女做 temperature cros那們slinking.

Thermosetting polyimide has exc讀得ellent thermal 友村stability, chemic紅物al resistance and mechanical空個 properties and is usuall商冷y orange in color. The f問劇lexural strength of grap嗎計hite or glass fibe關愛r reinforced polyimide can reach大子 345 MPa, and the flexural mod能廠ulus reaches 20 GPa. The use tempe金用rature range of polyimide covers a高票 wide range, fro愛黑m more than a hundred de制去grees below zero to two or three hundr但商ed degrees.
