F46

F46

Polyimide film coated with FEP adhesive offers excellent high-temperature resistance, chemical stability, and strong bonding. It provides reliable insulation and protection for electronics, automotive, and aerospace applications, ensuring durability in harsh environments.

6251 (F46) is a general-purpose polyimide film that is coated or laminated on one or both sides with FEP fluoropolymer. F46 provides heat sealability, moisture resistance, and enhanced chemical resistance. it is recommended for applications that require a heat-bondable film or superior moisture and chemical resistance beyond the capabilities of uncoated polyimide films.
