Reclaimed Rubber

Re-generated or Reclaimed rubber is produced by partial de-vulcanization of rubber granulate obtained from end-of-life tyres and other rubber products. The regenerated rubber has almost the original plasticity of virgin rubber, permitting the same to be compounded, processed and re-vulcanized or reused

  • TPS-NR, TPS-EPDM, TPS-Butyle

Re-generated or Reclaimed rubber is produced by partial de-vulcanization of rubber granulate obtained from end-of-life tyres and other rubber products. The regenerated rubber has almost the original plasticity of virgin rubber, permitting the same to be compounded, processed and re-vulcanized or reused.

 

Regeneration can occur either by breaking the existing cross links in the vulcanized rubber (partial de-vulcanization) or by promoting scission of the main chain of the polymer (breakage of C-C bonds) or a combination of both processes.

 

Partial De-vulcanization means selective cleavage or breakage of Disulphide (S-S) chemical bonds (see: Figure below) leading to the separation of natural rubber polymer chains using heat, mechanical shear force and assisted by peptizers (like process oil & pine tar oil) and reclaiming agent (like

Disulphides). The de-vulcanization is partial i.e. some and not all Disulphide (S-S) chemical bonds are broken. The main mechanism of de-vulcanization is by means of thermal – oxidative degradation and high shear force acting on the material.
