Product introduction

This testing machine is used for static load tests for adhesive strength Automatically count the time that the tape can remain under load and temperature to confirm the aging of the tape. Cut a 1 inch wide strip of tape and stick it on the specified SUS#304 stainless steel plate, roll it back and forth three times with a 2kg standard roll at a speed of 300mm per minute, hang the steel plate on the test machine , and add the specified weight, when the tape falls off the steel plate, the timer automatically maintains the test time, which is used to evaluate the persistence of the tape\'s adhesion. Applicable to the stickiness test of various self-adhesive products, such as pressure-sensitive tapes, plasters, medical plasters, adhesive labels, protective films, etc.
