tesa is a global technology leader in industrial tapes and adhesive solutions, and is part of the Beiersdorf Group. In the consumer electronics, automotive, home appliance, and packaging industries, tesa tapes are known for being "reliable"—and this reliability stems from extremely strict quality control. Dehui Scientific Instruments is proud to have been chosen by tesa as a supplier of laboratory testing equipment.

Working with a top global tape company like tesa requires comprehensive standards from suppliers. In terms of precision, the peel force tests for adhesive tapes (180° peel and 90° peel) demand very high resolution in the low force range (0.1N–100N)—even a deviation of only 0.5N could result in an entire batch being misjudged. The Instron universal testing machine, equipped with high-precision low-force sensors (10N or 50N range, 0.5 class accuracy) and pneumatic flat-clamp fixtures, is the ideal setup to meet this requirement.

Regarding data repeatability, tesa requires that the coefficient of variation (CV) of peel force data for samples from the same batch tested at different times by different operators be kept under 2%. This means the equipment not only needs to be highly precise but also follow standardized SOPs, and cross-verify with basic characterization data from the DSC and rotational rheometer.
