Product details

heat Resistant black polyimide film for voice coil

black Polyimide film is a lightweight, flexible material that has excellent heat and chemical resistant properties. and polyimid is used in a wide variety of applications such as substrates for flexible printed circuits, transformer and capacitor insulation, sensors and bar code labels.

Features:

* High temperature resistance up to 260C
* Class H insulation
* Easy for processing
* Stable and flame retardant

Application

Aerospace materials - The polyimid film is converted and layered together to make multi-layer insulation.

Automotive / Industrial materials - Polyimide films have excellent mechanical, electrical, temperature and chemical resistance making them optimal for demanding industries where performance is critical or harsh exposure conditions exist. Electronics - Polyimide film is the optimal substrate for high temperature applications like the electronics industry.

Labeling - Polyimide film, with the right printable coating applied, makes an excellent choice for labels used

in harsh environments.:
