RP-66

Mixture of organometallic complexes, derivatives of fatty acid and peptizer DBD

Blue granules

/

NR and high viscosity synthetic rubber

0.2-0.5phr

  •  Quickly reduce Mooney viscosity and improve processing properties.
  • Contains dispersing agent, it can be easily dispersed.

 

  • Effect from 80°C/176°F and reach optimum at 150°C /320°F.

RP-68

Mixture of 40% DBD and low melting point carrier

Blue granules

NR

0.1-0.5phr

  • DBD based chemical peptizer for NR, enhance chain-cut effect, and quickly reduce compound Mooney viscosity and processing time.
  • Can be mixed quickly at low temperature due to low melting point carrier. Effect from 70°C/158°F and reach optimum at 150-160°C.
  • Sulfur can inhibit plasticization of the product, and Mooney viscosity stays stable during storage.
  • Antioxidant should be added in mixing stage because usually antioxidant can inhibit plasticization.
