SBR Reclaimed rubber

Single Polymer, SBR De-vulcanized reclaim rubber


HIGH TENSILE 942+ PSI Hardness 50+ Shore A.


SBR F28E is a non-tire single polymer, 100% mechanically de-vulcanized slab rubber. The SBR master batch reclaim rubber sheets are fully un-cured, un-accelerated and ready for mixing or milling with sulphur cure pack. Rubber compounding and mixing companies use this SBR reclaim as virgin polymer replacement. It’s derived from new post-industrial rubber sprues and trims from rubber gasket manufacturing process. This is 100% metal free, guaranteed, tested and certified SBR master batch rubber.

SBR reclaim de-vulcanized rubber contents:

  • SBR Elastomer (100% SBR): 46%
  • Carbon Black: 33%
  • Process Oil: 14%,
  • Accelerants and stabilizers = 7%
