Performance Features

Excellent High-Temperature Stability

Polyimide film provides dimensional stability and reliable performance in elevated-temperature processes, including selected PCB soldering and electronic assembly applications.

Reliable Electrical Insulation

The polyimide backing offers dielectric properties suitable for electrical insulation, component protection and selected electronic manufacturing processes.

Silicone Adhesive Performance

The silicone pressure-sensitive adhesive is designed for high-temperature applications and provides adhesion to suitable substrates while supporting clean removal under appropriate conditions.

Low-Static Options

Specialized constructions are available for applications requiring reduced electrostatic charge during tape unwinding, application and removal. Low-static performance depends on the specific product construction.

Chemical and Dimensional Stability

Polyimide film offers resistance to many common industrial chemicals and maintains its shape under elevated temperatures. Actual performance depends on exposure conditions and process requirements.

Flexible Converting Options

STK supports customized slitting, roll converting and die-cutting for insulation components, PCB masking and other precision applications.
