Adhesion Strength and elongation
Adhesion strength is one of the key item of the quality. If the adhesion strength is weak, then the total strength of conveyor belt will become weak. What's more, the plies of fabric will leave from each other when the conveyor belts work. This will end the service life of the conveyor belt.
Here is the tech data of standard adhesion strength of our conveyor belt. If you request higher strength, tell us your application, we will design special conveyor belt for you.
