Filmetrics systems are widely used in the polymer films community to measure the thickness of films and coatings, and we have products specially designed for web inspection applications.
Web Inspection Applications
There are multiple points in plastic films manufacturing where coating thickness is critical to quality. These include: total film thickness (up to 400um), Coextrusion sub-layer thickness, and the thickness of coatings on a film web. In the particular case of coatings on PET our F20-UV can measure very thin layers (~10 nm) and even energetic plasma surface treatments. Our standard F20 can measure ubiquitous coatings such as hardcoats in the 0.05 to 50 um range.
We have an extensive refractive index database for a range of polymer films including PET, polycarbonate, cellulosics, and polyolefins, as well as more exotic materials such as conductive polymers.
Each of these applications offers a unique set of challenges and Filmetrics has developed the software, hardware, and applications knowledge to deliver the right solution.
For web inspection and general polymer film measurement, contact Dr. Jim Elman or any of our other thin-film experts.
Filmetrics offers free trial measurements – results are typically available in 1-2 days.
