What is the chemical stability of F46 polyimide film
2026-07-14The F46-PI film combines the chemical properties of PI substrate and FEP (perfluoroethylene propylene), with the F46 fluororesin insulating medium on the surface and polyimide on the inner layer to ensure substrate stability. The overall chemical resistance far exceeds that of pure PI film.

What are the advantages of bidirectional polyimide film compared to unidirectional stretching PI fil
2026-07-011. Mechanical properties are balanced in both directions, with no obvious shortcomings Unidirectional tensile PI only has high strength in the tensile direction (MD longitudinal), but poor transverse TD toughness: Bidirectional membrane: The longitudinal and transverse tensile strength, modulus, and tear strength are almost the same, with minimal anisotropy;

What should be noted when using unidirectional polyimide film
2026-06-10Full precautions for using unidirectional polyimide (single pull PI) film The characteristic of unidirectional PI is anisotropy: the longitudinal MD (tensile orientation direction) has much better strength, modulus, flexural resistance, and thermal dimensional stability than the transverse TD; the transverse MD is prone to tearing, has higher elongation, and thermal expansion. The first pri
