Bondply

DuPont™ Pyralux® TK bondply composites are constructed of DuPont™ Kapton® polyimide film coated on both sides with a fluoropolymer adhesive. Bondply is used to encapsulate two etched details for environmental protection and electrical insulation. Using bondply can eliminate a layer of Kapton® and a layer of adhesive in low count multilayer constructions.

Bondply Features:

• No tack for ease of registration
• Excellent encapsulation ability
• Available in thicknesses of 3, 4, and 5.5 mils
• Certified to IPC 4203A/5
