Request a Quote
Dyne test pen is an economical, efficient, quick, and simple device to measure surface humidity and energy of most polymer materials.
Dyne test pen is commonly used in corona surface treatment, plasma surface modification, and flame treatment processes to determine the surface energy and cleanliness of substrates. This is especially important in industries such as packaging, automotive, household products, medical, photovoltaic, and more.
Features
- If the drawn line is evenly distributed with no obvious pen dot or shrinkage, it indicates the surface tension of the film is higher than the value of Dyne test pen.
- If the drawn line slowly shrinks, it indicates the surface tension of the film is slightly lower than the value of Dyne test pen.
- If the drawn line immediately shrinks and forms pen dots, it indicates the surface tension of the film is much lower than the value of Dyne test pen.
