Property: Abrasion resistance Explanation: The property of resisting wearing away of surface by friction is known as abrasion resistance. It is measured by machines in which an abrasive material is rubbed against the surface of the rubber. The loss in volume in a definite period denotes the loss on abrasion. The greater the loss, less is the abrasion resistance.
Explanation: Tack is the special property of rubber due to which two or more surfaces can stick or adhere to each other. Tack can be increased by making the surfaces fresh by treating it with suitable solvent. It is an important property in manufacturing of tyres.
