Applicable Base Polymer Properties

Natural rubber 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. Solvent borne natural rubber has an affinity to wet large amounts of dry ingredients. 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 adhesive formulation is adhesion of films. It is used in applications where compound adhesion is critical and large amounts of plasticizer must be avoided. Natural rubber can be used because of its reactivity. Once cured, it will not migrate over time as typical oils do.
