Kapton flat washer / KK
This product is a flat washer made of polyimide film (Kapton) that has excellent heat resistance, electrical insulation properties, and mechanical characteristics. It is used by inserting it between the fastening material when tightening bolts or screws. By distributing the load during tightening over a wide area, it reduces the stress on the tightening surface, helps prevent dents and scratches on the counterpart material, and protects the seating surface. Additionally, using a flat washer stabilizes the fastening surface and supports the tightening condition of the bolts or screws. In addition to the excellent heat and cold resistance unique to polyimide film (Kapton), it also possesses high electrical insulation properties, radiation resistance, and dimensional stability. This film-based flat washer is suitable for fastening and insulating applications in electrical and electronic devices, various circuit boards, and precision instruments where electrical insulation and heat resistance are required.
