Effective recycling of end?of?life polyvinyl chloride foams in ethylene–propylene diene monomers rubber

Rigid cross-linked interpenetrated network polyvinyl chloride (PVC) foams are widely used as core materials in the composite industry. Nevertheless, no recycling methods exist today for these that currently landfilled at end of life (EoL). In this work, various amounts EoL PVC form chips were mixed with ethylene–propylene diene monomer (EPDM) rubber and carbon black (CB) 60°C 15 min. The obtained mixtures vulcanized 160°C 20 min to create compacted square sheets EPDM-CB-PVC composites using compression molding technique. Tensile tests revealed a progressive increase modulus EPDM-CB increasing content while subsequent decrease elongation-at-break values was noticed. Scanning electron microscopy homogeneous dispersion particles matrix. Improved interfacial adhesion filler matrix also observed higher well. Hardness an increased Shore A by 25% added waste EPDM-CB. Concurrently, steady set filler. Additionally, due filler, thermal conductivity decreased 35% compared pure
