CAPLINQ LINQSTAT XVCF-S Series is highly conductive volume conductive polyethylene film similar to our standard VCF-Series film but with a higher electrically conductive carbon loading and a denser polymer mix. This combination allows us to offer to grades of XVCF-Series films: XVCF-BTS Series and XVCF-ALS Series.
XVCF-BTS Series: 250 ohms-per-square Surface Resistivity
Our LINQSTAT XVCF-BTS Series films have a higher carbon loading than our standard VCF-Series films. This higher carbon loading gives us a lower resistance and as such, a higher conductivity. We come to a physical limit on how much carbon this plastic can be loaded before other properties are adversely affected, and so to get even more conductivity, we need to go to a more dense polymer matrix as we have done with our XVCF-ALS series films. The result of this denser matrix is a higher conductivity and better mechanical properties, but this comes at a cost penalty that can make the XVCF-ALS Series film up to ten times more expensive.
XVCF-ALS Series: 50 ohms-per-square Surface Resistivity
Our LINQSTAT XVCF-ALS Series films are our most conductive to date. Using a premium polymer and process, we are able to increase the conductivity and thus reduce the surface resistance of the plastic to as low as 50 ohms-per-square. This premium polymer requires also that we use a premium process to produce the film, which has a consequence that the price of the material can be as high as ten times the price of the XVCF-BTS Series films. If your application justifies the price, and you want the best conductive plastic, then our LINQSTAT XVCF-ALS Series films are the best we can offer.
CAPLINQ LINQSTAT™ XVCF-S Series conductive films are thin, lightweight and relatively inert. Furthermore, they are are well suited for applications requiring electrochemical reactions, high conductivity or charge storage including but not limited to electrodes (ECG, TENS, Defibrillation and Iontophoresis), batteries (flat-cell zinc/manganese dioxide (MnO2), Lithium Ion and Lithium polymer), and digital (electronic) white boards.
CAPLINQ LINQSTAT XVCF-S Series film and its conductivity are unaffected by humidity and age. The film is heat-sealable, flexible and offers exceptional abrasion resistance. The film gives good thermal stability and has outstanding chemical resistance. It has a standard thickness range from 50μm to 100μm (2 mil to 4 mil) and is available in various lengths, widths and thicknesses.
Product Applications
Given its low surface resistance, LINQSTAT XVCF-ALS Series films have been successfully used as a pressure sensor making it useful for applications that require more conductivity to be able to detect more subtle pressure differences. For less-sensitive pressure sensor applications or applications that have larege surface areas and/or higher application pressures, CAPLINQ LINQSTAT VCF-Series may be sufficient. Examples of applications that use the material as a pressure sensor is in the manufacture of digital whiteboards.
Due to its low-resistivity and its resistance to a range of chemicals and alcohols, LINQSTAT XVCF-ALS Series films are suitable for use in electrodes. Its matte finish allows it to be printed on, and the low material thickness makes it flexible to adapt well to a range of contours.
