6251 Polyimide tape is a general polyimide film that is coated or laminated on one or both sides with FEP Fluoropolymer, which imparts heat sealability, provides a moisture barrier, and enhances chemical resistance.
6251 Polyimide tape is recommended in applications that require a heat bondable film, or moisture and chemical resistance beyond the capabilities of uncoated polyimide film.
Applications
Tubing
Heater circuits
Heat sealable bags
Automotive diaphragms and manifolds
Electrical insulation

This polyimide film is similar Dupont Kapton HN, but compared with Kapton HN that is more economical.
Like properties of other polyimide film, this thermal conductive polyimide film with good thermal conductive property, could work at the condition from -269â?? up to 400â??.
This polyimide film designed by our factory is absolutely alternative to dupont kapton HN, has excellent dielectric strength, electric dissipation factor, wide temperature range, chemical resistance at elevated temperatures, compared with Dupont Kapton HN that is more economical.
Certification: ISO9000:2008, UL, SGS
Mainly used in electrical and electric insulation application:
1) Formed coil insulation
2) Substrates for FPC
3) Motor solt liner
