Please contact us for pricing and availability. Product code: CKA

 

We supply uncured rubber compound from custom rubber mixing plants. This is scrap rubber compound, with the cure pack but material is in sheets and slabs, un-cured form.  These are for different applications such as rubber belting, retread treads and molded rubber parts. There some straight SBR rubber compounds, some can be blends of SBR/NR rubber compounds and some SBR/PBR/NR rubber compounds.

These are their general properties of the scrap rubber compounds. Properties of individual skids may vary, these are listed to give you a general idea.

  • Tensile ~2000 PSI
  • Hardness 60-64 Durometer Shore A
  • Elongation at break ~450
  • Loading 20 MT per shipment
  • Availability 20 to 60 tons per month on ongoing basis

All scrap rubber compounds are stored inside, in normal working condition temperatures. We do not grade the material similar to uncured tire compounds, however this is what we would consider good enough for re-mixing. This low cost rubber compound works for various wide spec applications including conveyor belts and engineered rubber parts made from low cost rubber compounds.
