The adhesive strength of tape is an important indicator, which is related to the normal operation of tape. The same applies to medical tape, which not only requires a certain amount of adhesion, but also cannot be too strong to prevent skin damage. So now it’s up to Xinhao Medical tape manufacturer Teach you to test the adhesive strength of the tape.

It is to prepare measuring instruments, mainly including medical tape test pieces, peeling machines, steel sheets, and rollers. Different medical tape test pieces should be marked and the initial adhesion force and holding force should be measured separately.

Initial adhesion force

Place the initial viscosity tester horizontally on the workbench and adjust the inclined surface of the rolling ball table by 30 degrees; Corner. Then remove the silicone paper from the test piece, with the adhesive facing upwards, and use transparent tape to stick 50mm up and down each. Fix the tested surface flat on the inclined surface of the tester. Wipe the steel ball with ethyl acetate, then place the rolling ball in the ball placer on the upper end of the rolling ball table. Gently press the ball placer, and the rolling ball will immediately slide down along the inclined table onto the test piece. Select the size of the ball and adjust its different sliding trajectories. Record the larger ball number adhered, which is the initial adhesive force of the tape measured this time

Adhesive force

First, use ethyl acetate to paste the experimental plate and loading plate onto the middle part of the experimental plate and loading plate, and roll the test piece back and forth three times using a pressure roller. After pasting the test piece on the board, fix the test piece vertically on the experimental frame, and fix a 500g weight on one end of the loading plate. Record the start time of the test until the test piece slides off the steel plate.

This is the testing method for the adhesive strength of medical tape. We hope that the information provided by Xinhao Medical Tape Manufacturer can be helpful to you. If you need more information, please contact Hangzhou Xinhao Medical Technology Co., Ltd., hotline: 0571-64827969
