Applicable Base Polymer Properties

DPR 75 is a liquid natural rubber product for use in rubber compounding and tire manufacturing. It is particularly useful as a general rubber compounding ingredient because it is natural rubber-based and can be reacted over the entire cure spectrum of natural rubber. Liquid natural rubber has an affinity to wet large amounts of dry ingredients and can be cured to a very hard matrix. Natural rubber has good resistance to water and to mold, but poor resistance to oil, solvents, and low temperatures.

Resulting Properties

A major application area for this 1K, Heat Cured Natural Rubber Cable Sealant formulation is the electrical cable industry and other areas. It is used in applications where compound adhesion is critical and large amounts of plasticizer must be avoided. Liquid natural rubber can be used because of its reactivity. Once cured, it will not migrate over time as typical oils do. The source of this formulation is DPR Industries.
