Abstract
ABSTRACTThermoplastic elastomers (TPEs) based on high-density polyethylene (HDPE)/waste ground rubber tyre (WGRT) powder blends were prepared by melt-compounding where styrene–butadiene–styrene block copolymer (SBS) was used as compatibiliser. Mullins effect and its reversibility of the prepared TPEs under compression mode were investigated systematically. The results showed that the stress softening, residual deformation and hysteresis could be observed obviously during the cyclic uniaxial loading–unloading tests. Compared with that of the HDPE/WGRT blends, the compatibilised TPEs had a slight stress softening. Increasing the heat treatment temperature and the SBS dosage could strengthen the reversibility of the Mullins effect remarkably.
