2 provides the SEM micrograph of recycled EPDM
particles at 100 magnification. The recycled EPDM particles
were irregular and rough in shape and often found in
aggregates, which were broken by the mechanical crusher.
The specific gravity of the powdered R-EPDM was 1.06 g/cm3
.
The carbon black content in recycled EPDM was 29.33%,
which was obtained from the TGA results
