Testimonial

“We exposed samples of Kapton and VTEC (cast into films) to a continuous-wave 325nm laser and found that where the Kapton film would seemingly ‘bubble’ up / ablate / etch, nothing happened to the VTEC. We even decided to leave it under the laser for 2 hours and still there were no visible marks! Is this down to the thermal conductivity coefficient (which is several orders of magnitude lower than that of Kapton) or some other wonder of indestructibility?
