Paraffin　based　composite　phase　change　materials　(PCMs)　have　gained　intensive　attentions　in　low　temperature　thermal　energy　storage　(TES)　and　management　application　domains　because　of　its　suitable　melting　temperature　range　and　advanced　thermoproperties.　Seeking　decent　structural　supporting　materials　(SSM)　and　the　associated　manufacturing　approaches　that　capable　of　fabricating　paraffin　composites　at　appropriate　temperatures　to　avert　the　thermal　decomposition　of　the　paraffin　particularly　for　low-molecule　ones　are　in　high　demand.　Herein,　we　developed　a　low-molecule　paraffin　(RT18HC)　composite　through　a　simple　blending　approach　by　using　styreneethylene/butylene-styrene　(SEBS)　as　SSM,　and　showed　that　such　SEBS-paraffin　composites　could　be　able　to　fabricate　at　a　low　operation　temperature　of　80　degrees　C,　significantly　lower　than　that　required　for　the　preparation　of　conventional　high　density　polyethylene　(HDPE)-paraffin　composites.　To　enhance　the　composite　effective　thermal　conductivity,　a　micro-sized　graphite　power　as　enhancer　was　also　involved　over　the　fabrication　process.　Owing　to　the　desirable　solubility　of　paraffin　in　SEBS,　a　crosslinking　structure　inlaying　paraffin　and　graphite　was　formed,　endowing　the　composite　with　ability　to　maintain　the　structure　stabilization　and　eliminate　the　graphite　sedimentation　over　the　repeated　thermal　cycles.　10　wt%　of　SEBS　gives　the　composite　optimum　formulation　at　which　10　wt%　graphite　can　be　involved,　and　also　an　excellent　shape　stability　and　thermal　adjustment　ability　can　be　achieved.
