Crack-Resistant Rigid Polyimide Insulation Sheets

Even when subjected to heavy compression, these rigid polyimide sheets won't crack.

Flame-Retardant Sound-Absorbing Sheets

This insulation meets ASTM E162 for flame retardance and ASTM E662 for smoke output. Use to quiet noisy areas and line machine enclosures. Sheets are made of polyimide foam.

Raw Materials

Lightweight High-Temperature Polyimide Foam Sheets

In addition to being lighter in weight than silicone foam, this polyimide foam also remains soft and conformable across a broader temperature range.

Electrical-Grade Kapton® Polyimide Film

Kapton® polyimide film is an excellent electrical insulator.

Thermally Conductive Kapton® Polyimide Film

Because this film dissipates heat, it is often used for printed circuit boards and power supplies.

Tape

Electrical-Insulating Mounting Tape

This chemical-resistant tape has adhesive on both sides.

Antistatic Electrical Tape

A coating on this polyimide tape minimizes ESD (electrostatic discharge) when unwound from the roll and also during removal.

Heat-Transfer Tape

Quickly conduct heat away from electronic components. Kapton® polyimide gives this tape excellent electrical isolation.

Super-Thin Masking Tape for Electronics

At half the thickness of our other masking tape for electronics, this polyimide tape conforms easily to components.

Masking Tape for Electronics

Use this tape to wrap and splice cables, mask components while soldering, or as a 3D printing surface.

Masking Tape Shapes for Electronics

Use these convenient cut shapes to mask holes, fastener heads, and small areas while soldering.

Heat-Shielding Tape

This tape reflects intense heat to protect sensitive components.
