DPRŽ Liquid Natural Rubber

The DPR products are low molecular weight, liquid polymers of natural rubber. The chemical backbone is cis-1,4 polyisoprene. DPR liquid rubber offers processing flexibility and performance options for a wide range of applications. Liquid natural rubber improves rubber and polymer compounding and final processing. It acts as a plasticizer to reduce cycle time and energy consumption. Since it cures by the same mechanism as natural rubber, it becomes part of the polymer matrix and remains non-fugitive. This extends the life of the finished products.

Typical Applications

DPR liquid rubber provides all the performance properties of natural rubber in a convenient liquid. Liquid rubber performs many functions in a wide range of applications:

  • Polymer binder for grinding wheels and friction products
  • Reactive rubber processing aid
  • Reactive vehicle for rubber additives
  • Rheology modifier for lubricants
  • Polymer base for molding and tooling systems
  • Polymer base for electrical encapsulants
  • Polymer base for automotive sealants and sound damping compounds
  • Asphalt modifier
