Technical Data Sheet

TapeCase Double Coated Polyimide Tape DC-B is a 1 mil polyimide film coated on both sides with a high temperature silicone adhesive and supplied with a PET film liner for easy handling.

DC-B offers excellent thermal and chemical resistance, strong electrical insulating properties, and a wide operating temperature range up to 500°F. Its dimensionally stable construction resists shrinking, stretching, and warping when exposed to elevated temperatures. The thin and conformable polyimide film provides excellent puncture and tear resistance, even in demanding high heat environments.

The silicone adhesive delivers reliable high temperature adhesion while allowing for clean, residue-free removal after thermal exposure.

DC-B is commonly used for high temperature bonding and insulating applications.

High temperature mounting and bonding applications
Electronic assembly applications
Electrical insulating applications
Bonding and laminating in many applications that require positive dielectric separation
Bonding applications where both surfaces are silicone treated or coated
Splicing insulation layers
