## FAQ
[What is the Dyne? How does it measure surface tension?](https://www.ferben.com/contacts/faq/what-is-the-dyne-how-does-it-measure-surface-tension.kl): The dyne is a unit of force in the CGS system (centimetre - gram - second), used mainly in science, for example in the study of surface forces or microscopic interactions.
[Why Dyne is important to measure the surface tension of plastics?](https://www.ferben.com/contacts/faq/why-dyne-is-important-to-measure-the-surface-tension-of-plastics.kl): For plastics, measuring surface tension is essential to determine how inks, varnishes, adhesives or other coatings adhere to the surface of a substrate. The surface tension must be sufficiently high to achieve a quality print or optimum adhesion.
[What is the unit of surface tension?](https://www.ferben.com/contacts/faq/what-is-the-unit-of-surface-tension.kl): Surface tension is expressed in dyne per centimetre (dyne/cm) or mN/m.
[What substrates can I perform Dyne tests on?](https://www.ferben.com/contacts/faq/what-substrates-can-i-perform-dyne-tests-on.kl): Dyne tests can be carried out on a wide range of substrates: plastics, metals, glass and rubber. For the test to work, the surfaces to be tested must be smooth and non-porous (porous surfaces will absorb ink and invalidate the test).
[What is the Dyne Test Ink?](https://www.ferben.com/contacts/faq/what-is-the-dyne-test-ink.kl): Dyne Test Ink is a liquid mixture used to measure accurately the surface tension of plastic and non-plastic substrates. The mixture is applied to the surfaces to be tested to determine the exact value in dyne/cm and whether the adhesion will be good or poor.
[How is Dyne Test Ink used?](https://www.ferben.com/contacts/faq/how-is-dyne-test-ink-used.kl): Use the brush supplied to apply a small amount of the liquid mixture to the surface to be tested. If the applied liquid breaks up into droplets in less than 2 seconds and does not spread, the surface tension is too low.
[Why do some materials have low surface tension?](https://www.ferben.com/contacts/faq/why-do-some-materials-have-low-surface-tension.kl): The main causes can be: contamination of the surface by dust, oils, residues previous processing, such as hot forming or extrusion, which can leave residues on the surface type of plastic.
[Which plastics can be tested with Dyne Test Ink?](https://www.ferben.com/contacts/faq/which-plastics-can-be-tested-with-dyne-test-ink.kl): Polyethylene (PE) Polypropylene (PP) Polystyrene (PS) Polyethylene terephthalate (PET) POLYVINYL CHLORIDE (PVC) Teflon (PTFE) Polyamide (PA) Recycled materials
[Can Dyne Test Ink handle recycled plastics?](https://www.ferben.com/contacts/faq/can-dyne-test-ink-handle-recycled-plastics.kl): Yes, Dyne Test Ink can be used on recycled plastics such as PET, PE or PP plastics, which often have a lower surface tension than virgin materials and therefore require careful testing to determine if adhesion with inks, paints or coatings of any kind is possible.
[How long does it take to test with Dyne Test Inks?](https://www.ferben.com/contacts/faq/how-long-does-it-take-to-test-with-dyne-test-inks.kl): The test is very quick. It usually only takes a few seconds to apply the ink to the surface and observe its behaviour.
[Are tests affected by environmental factors?](https://www.ferben.com/contacts/faq/are-tests-affected-by-environmental-factors.kl): Yes, factors such as humidity, temperature and surface contamination can affect test results. To obtain accurate results, the test should be carried out in a controlled environment and the surface of the material should be as clean as possible.
[What is the difference between Dyne Test Ink and Dyne Test Pen?](https://www.ferben.com/contacts/faq/difference-between-dyne-test-ink-and-dyne-test-pen.kl): Dyne Test Ink is a liquid mixture applied to the surface of the material to be tested using a brush or applicator. It is designed for extensive testing and laboratory use and accurately indicates the numerical value, expressed in dyne/cm, of the surface tension measured.
[What is the difference between the Dyne Test Pen and the Corona Marker?](https://www.ferben.com/contacts/faq/what-is-the-difference-between-the-dyne-test-pen-and-the-corona-marker.kl): The Dyne Test Pen quickly measures whether a material has been previously corona treated, leaving the surface untouched after the test.
[Why is the Dyne Test Pen only available in 38?](https://www.ferben.com/contacts/faq/why-is-the-dyne-test-pen-only-available-in-38.kl): Considering that most inks and adhesives still have surface tensions above 38, 38 is considered the threshold for accepting or rejecting a substrate.
[Are Dyne Test inks with values lower or higher than 38 also available in pen format?](https://www.ferben.com/contacts/faq/are-dyne-test-inks-with-values-lower-or-higher-than-38-also-available-in-pen-format.kl): No, the Dyne Test inks produced and marketed by Ferrarini & Benelli are only available in bottle format.
[Are marker refills available?](https://www.ferben.com/contacts/faq/are-marker-refills-available.kl): No, refills are not available.
[What is the shelf life of Dyne products?](https://www.ferben.com/contacts/faq/what-is-the-shelf-life-of-dyne-products.kl): To ensure accurate test results, it is recommended that inks and markers are used no later than 6 months from the date of opening.
