Cord Adhesion Tester

Test mechanism:

LDN-II Cord Dynamic Shear Adhesion Tester allows the cord inside the square sample of vulcanized rubber with its 2 ends fixed by different weights at a pre-set temperature (from room temperature to 100°C). During testing, the rubber sample will assume on a reciprocating movement along the extension of the cord with certain amplitude and frequency, and thereby generates a continuing dynamic shear at the interface between the cord and the rubber. With repeated shear deformation, the adhesion at the interface between the cord and rubber gradually decreases until reaching a certain pre-set value. By measuring the time or numbers of deformation required of the adhesion between cord and rubber when they reach a pre-set level, the adhesive properties of the cord and rubber under dynamic conditions can be indicated.
