  • Products produced by the addition of white mineral oils (WMO) and hydrocarbon process oils (PO) into
    Engage* Polyolefin Elastomers (POEs), produced via constrained geometry catalysis (CGC), are currently used in thermoplastic elastomer applications. The selection of oils for use with semi-crystalline elastomers depends upon the oil characteristics and the polymer's ability to accept the required amount oil to achieve the desired properties. This paper will discuss the interaction of POEs with various WMOs and POs and offer some guidelines on the useful incorporation range of the different oils and the resulting properties. Comparison to a similarly formulated, non-CGC polymers will also be discussed. Depending on the density or specific gravity of the base POE, over 50% by weight of a mid-viscosity oil was incorporated without oil loss by exudation. Lo\ver hardness and mechanical properties with improved processability were a result of oil incorporation. Changing the type of oil showed little effect on the hardness and mechanical properties (modulus and tensile strength) of the compounds. The WMOs did demonstrate good initial color and less color change after storage compared to the POs.
