LINQSTAT VCF-4S200K is a black, carbon-filled, electrically conductive polyethylene plastic film designed to provide both physical and static protection. Having a surface resistance of < 200,000 ohm-sq, (2x105 Ω-sq) it offers medium-level static protection which means it effectively avoids accumulation of electric charge on itself and the products which it protects. Its easy-grounding nature makes it ideal for packaging where electrostatic contamination is a problem. Keep in mind that the value is "below 200,000ohms-sq" and not an absolute number.
VCF-4S200K is useful in applications where the key is to balance cost versus performance. As a medium-level conductive plastic, the carbon-loading is such that it is low-enough to be cost-effective, while being high enough to meet the electrical requirements of military specification MIL-PRF-81705D Type II and MIL-P-82646A. It is typically used as an antistatic smartcard and micromodule interleaver.
VCF-4S200K film and its conductivity are unaffected by humidity and age. It gives good thermal stability and has outstanding chemical resistance. It has a standard thickness of 4mil(0.1mm) and is available in 35mm rolls, ideal for smartcard and micromodule interleaving applications.
In sheet form, LINQSTAT VCF, works as an antistatic plastic. For more sensitive pressure sensor applications, CAPLINQ recommends LINQSTAT XVCF-Series, which is a more-conductive series of polyethylene plastics. As an antistatic packaging plastic, it is also used as a antistatic interleaver for Smartcard (micromodule) applications to separate subsequent layers of smartcard chips in micromodule production.
