The DPR products are low molecular weight, liquid polymers of natural rubber.

DPR® 35 offers the lowest viscosity of the product line. It is the easiest product to pour and is the most efficient plasticizer of liquid rubber products. DPR 35 liquid rubber is compatible with many solvents, plasticizers, resins and reinforcements. It increases the polymer’s capacity for fillers and improves the acceptance of non-compatible reinforcements.

DPR® 35

DPR® 40 is a low viscosity grade of the DPR liquid rubbers. When used as a processing aid, DPR 40 demonstrates greater reduction in plasticity than the higher viscosity grades of DPR.

DPR® 40

DPR® 400 is the most viscous of the DPR liquid rubbers and accepts the maximum extension of plasticizer and filler. When used as a processing aid, DPR 400 demonstrates slightly higher retention of cured physical properties as compared to the lower viscosity grades of liquid natural rubber.

DPR® 400

DPR® 75 offers an intermediate viscosity grade within the product line. Its viscosity provides an optimum balance between the lower viscosity needed for easy processing and the thickness required to bind aggregates and other highly loaded systems.
