CHR® K109 and K350 are manufactured from polyimide film with high-temperature adhesive.

• 2 mil polyimide pressure sensitive adhesive tape
• Good mechanical and electrical properties as well as a high conformability
• Outstanding resistance to cut through and are impact and abrasion resistant
• Acrylic adhesive can be thermoset
• Backing thickness and Adhesive thickness are 0.051 and 0.038 mm

They also offer excellent dielectric strength, while the burning of the adhesive forms a non-conductive ash. Both K series are designed to fill the various needs of electrical insulation requirements.

CHR® K109 and K350 are constructed to fill the requirements of a high performance thermoplastic polyimide backing materials. CHR® K109 and K350 are designed to fill the various needs of electrical insulation requirements.
