BH amber polyimide film is a kind of biaxial tension PI film. Its thickness tolerance is small, and coefficient of thermal expansion(CTE) is low. This film is widely used for substrate of FCCL.
Small thickness tolerance
FCCL basement material
Available thickness: 12.5um
Smooth, semi-transparent amber color without broken, bubble,pinhole and foreign impurity.
The polyimide film is manufactured by two direction tension after film casting, it possesses heat-resistant, radiation resistant and good mechanical performance.
Film is produced by polymerization of PMDA & ODA as main raw material, after casting, drying, then, winding into roll.It has excellent dimension stability,and good thermal, physical, chemical character.
After winding on carboard tube core or plastic tube core, then, be packed in plastic bag, wrapped with bubble parper, two ends with end cap, then, be packed in carton.
