The DPR products are liquid natural rubber (NR) with low molecular weight. When added at levels of 5 to 20 phr, DPR improves blend consistency, reduces the risk of scorching and minimizes mixer power consumption. DPR is compatible with both NR and a variety of synthetic polymers such as IR, EPDM, PBR, SBR and CR.

Benefits:

Improve dispersion of rubber and polymer compound in final processing. 

DPR is not processing oil. DPR cures by the same mechanism as NR.

It becomes part of the polymer matrix and remains non-fugitive. This extends the service life of finished products.
