| Summary: | Recovery of recycled acrylonitrile–butadiene–
styrene (ABS) through mixing with styrene-ethylene/butylenestyrene
(SEBS) has been studied in this paper. To simulate
recycled ABS, virgin ABS was processed through 5 cycles, at
extreme processing temperatures, 220 ºC and 260 ºC. The
virgin ABS, the virgin SEBS, the recycled ABS and the
mixtures were mechanically characterized after the various
cycles of reprocessing in order to evaluate their corresponding
properties and correlate them with the number of cycles
undergone. The results show that tensile strength of ABS
remains practically constant as the number of reprocessing
cycles increases, while in the material injected with SEBS the
tensile strength decreases. Concerning the Charpy notched
impact strength; the values of the ABS reprocessed at 220 ºC
remain more or less unchanged, while the values for 260 ºC
show a significant decrease. The adhesion of the SEBS causes,
in both cases, an increase in impact strength. |
