Liquid Natural Rubbers
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.
