A DIN Abrasion Tester is used to measure the abrasive resistance of rubber as a function of volume loss. A piece of rubber is held against a rotating drum covered in paper of known roughness for a set amount of time. As the drum rotates against the rubber, small particles will gradually wear away, flattening the surface of the sample.
The effects of blend ratio on cure characteristics, mechanical properties, morphology, and the resistance to oil, thermal ageing, and ozone of blends based on epoxidized natural rubber (ENR) and natural rubber (NR) have been investigated in the presence of silica selected as a reinforcing filler due to its unique characteristic to interact with ENR.
