Kapton tape: Low Static Polyimide Film Tape KD801/802 is a polyimide film-backed silicone adhesive tape with extremely low electrostiatic discharge properties. Product Construction KD801 KD802 Backing Polyimide Polyimide Adhesive Silicone Silicone Technical Data Product Units KD801 KD802 Test method Backing Thickness: mm 0.025 0.025 Total Tape Thickness: mm 0.040 0.066 Adhesion to Steel: N/cm 3.5 6 GB-T2972-98 Tensile Strength at Break: N/cm 58 58 GB-T7753-87 Elongation at Break: % 60 60 GB-T7753-87 Upmost use Temperature : ° C 280 280 Surface resistance: ohms >106 >106 Static Charge: Removal from roll: V <100 <100 Removal from SUS: V <50 <50 Dielectric Strength volts 8000 GB/T7752-87 Application Mask for printed circuit boards during wave solder or solder dip process Features Employs a proprietary technology that results in extremely low electrostatic discharge at unwind and removal form SUS. Conventional polyimide tape typically generate over 10,000volts during use which can damage around electronic components . The low static properties of KD801/802 can eliminate circuit board degradation. Storage Details Store under normal conditions of 10° to 30°C and 40 to70% R.H. in their initial packaging. shelf life is 6 months from the date of manufacture. Remark The above technical parameters established in our experimental data, may be due to the different usage and experience vary, so we suggested to do a test before using.
