H Type Polyimide Film is produced by polymerizing and casting 4-formic
acid-2-anhydride of benzene and 4.4-diamino-diphenyl-ether oxide
Main Performance of H Type Polyimide Film:
1) Excellent performance of insulation and mechanism
2) Excellent resistance to high temperature and wide range of working
temperature ? 60oC to +250oC for long time working and up to
+400oC for short time working without any modification in
electrical and mechanical properties
3) Excellent chemical stability. Resistance to most organic solution,
no corrosion made of the PI film by any inorganic acid and alkali
except for caustic alkali
4) Excellent resistance to flame
5) Excellent resistance to radiation
