Roll handling, slitting and converting

Can roll tension during converting stretch the material beyond its qualified state?

C-POLAR publishes no tension limit for converting.

A converting process is qualified by the converter that runs it, on the material as it is delivered.

The Terms of Use state: “A prospective partner or manufacturer must perform its own testing, validation, compatibility work, safety review, risk review, and quality controls for its proposed product and use.” They also state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.”

What the company states about the material itself is a measurement. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
