Raw Materials

Electrical-Grade Kapton® Polyimide Film

Kapton® polyimide film is an excellent electrical insulator.

Electrically Conductive Kapton® Polyimide Film

This film conducts electricity to prevent the buildup of static charges.

Thermally Conductive Kapton® Polyimide Film

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

High-Strength Vespel® Polyimide

Vespel® polyimide offers excellent strength, even at extreme temperatures.

High-Temperature Plastic Selector Packs

One 2” square of PEEK, PFA, polyimide, Torlon PAI, and Ultem PEI is included in these selector packs.

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.

Fastening and Joining

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.

Super-Thin Masking Tape for Electronics

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

Heat-Shielding Tape

This tape reflects intense heat to protect sensitive components.

Antistatic Electrical Tape

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

Electrical-Insulating Mounting Tape

This chemical-resistant tape has adhesive on both sides.

Heat-Transfer Tape

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

Peel-Away Layered Shim Stock

Cut this shim stock into custom shapes to fit your application. Stock is made of layers of material bonded with adhesive; remove layers with a utility knife until you get the thickness you need.

Heating, Venting, and Air Conditioning

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.
