LINQSTAT Electrically Conductive Plastic Film gets Tighter Specifications

As with most prod­uct lines, our LINQSTAT line of elec­tri­cal­ly con­duc­tive plas­tic films has grown so much that it has out­grown its orig­i­nal pur­pose. Orig­i­nal­ly designed to be a line of anti­sta­t­ic prod­ucts, cus­tomers start­ing ask­ing us more and more if we could increase the con­duc­tiv­i­ty of the plas­tic to make it more con­duc­tive. This meant that the prod­uct (though remain­ing anti­sta­t­ic) filled more of the role of an elec­tri­cal­ly con­duc­tive plas­tic film.

Some VCF-Series prod­ucts have been reclas­si­fied as MVCF-Series, and new prod­ucts have been intro­duced in the VCF‑, MVCF, and XVCF-Series.

The need for more electrically conductive plastic films

Orig­i­nal­ly designed for anti­sta­t­ic pack­ag­ing, CAPLINQ has fur­ther devel­oped its line of LINQSTAT elec­tri­cal­ly con­duc­tive plas­tic films to tru­ly be elec­tri­cal­ly con­duc­tive. Heav­i­ly-loaded plas­tic films com­pete with oth­er tech­nolo­gies that CAPLINQ offers such as graphi­tized car­bon paper and pan­els, and Acti­vat­ed Car­bon Fab­ric which are used pri­mar­i­ly for gas dif­fu­sion lay­ers for fuel cells and electrolyzers.

The advan­tage of the elec­tri­cal­ly con­duc­tive plas­tic film in this case is that they are avail­able on rolls and are not brit­tle (like the car­bon paper and pan­els), and they are very thin and con­tain the car­bon with­in the medi­um (as opposed to the acti­vat­ed car­bon fab­ric). Fur­ther­more, they are quite cost-effec­tive, mak­ing them attrac­tive for elec­trolyz­er appli­ca­tions look­ing to replace expen­sive cur­rent col­lec­tor parts.

Reclassification of LINQSTAT Electrically Conductive Plastic Films

As men­tion above, in many cas­es, there is no change at all to the old LINQSTAT VCF-Series prod­ucts. For exam­ple, the old prod­uct VCF-80036S/2 had a sur­face resis­tiv­i­ty val­ue of <200,000 ohms/square which is a very wide spec­i­fi­ca­tion. As we start­ed get­ting into more spe­cif­ic appli­ca­tions, cus­tomers start­ed request­ing tighter con­duc­tiv­i­ty tol­er­ances to meet more demand­ing appli­ca­tions. As a results, we split our VCF-Series busi­ness into three groups:

  1. LINQSTAT VCF-Series: Our low-lev­el elec­tri­cal­ly con­duc­tive plas­tic film with a sur­face resis­tiv­i­ty from 50,000 — 200,000 ohms/square
  2. LINQSTAT MVCF-Series: Our medi­um-lev­el elec­tri­cal­ly con­duc­tive plas­tic film with a sur­face resis­tiv­i­ty from 1,000 — 50,000 ohms/square
  3. LINQSTAT XVCF-Series: Our high-lev­el elec­tri­cal­ly con­duc­tive plas­tic film with a sur­face resis­tiv­i­ty from 1 — 1,000 ohms/square

The VCF-80036S/2 already was a more con­duc­tive prod­uct, and so the change in name reflects only a repo­si­tion­ing of its prop­er­ties, but no change chem­i­cal­ly to the prod­uct itself.

CAPLINQ is a spe­cial­ty plas­tics sup­pli­er offer­ing a range of con­duc­tive mate­ri­als includ­ing our broad range of elec­tri­cal­ly con­duc­tive plas­tics and anti­sta­t­ic tapes and films.

  1. Can I buy lin­q­s­tat from you. Please let me know how to buy linqstat.

  2. I was look­ing for specs on lin­q­s­tat RF absorb­ing and reflec­tion. All I see are ohms per square. My hus­band is a sci­en­tist. After watch­ing at work he wrote this back,

    The engi­neer does it all wrong. A DMM won’t cut it. Even his approx­i­ma­tion is slop­py. He’s mea­sur­ing par­al­lel resis­tance of a 3‑leg cir­cuit with his body, the mate­r­i­al stack, and the ruler. He needs to wear insu­lat­ing gauntlets or not lean on the mate­r­i­al. He needs to sep­a­rate patch­es, not stack. Mea­sure one in iso­la­tion. He also needs a wood or paper ruler, not met­al or plas­tic, since he’s mea­sur­ing a plas­tic. And real­ly the cor­rect instru­ment, which is not a DMM.”
