Plastomer, Polyolefin (POP)

Polyolefin plastomers (POP) are a range of copolymers based on metallocene catalysts utilizing butene or octene comonomers. Key characteristics of POP's are their low hardness, low density and high impact / toughness. These resins are commonly used in compounding applications where they improve the impact performance and flexibility of polypropylene or polyethylene-based compounds but they can also be used alone to produce molded and extruded parts and film with high flexibility and softness. POP's bridge the performance gap between conventional polyolefins such as polyethylene and conventional elastomers like ethylene propylene diene monomer (EPDM). The density of POP is typically in the range of of 0.886 to 0.912 g/cm3.

POP have garnered attention because of their low density, low melting point, chemical resistance, processing advantages, good resilience without permanent deformation, applications in plastic recycling, and relatively low cost. Demand for POP has grown at a significant rate. Ethylene POP’s unique properties make them desirable for flexible packaging, molded and extruded products, and elastomeric foamed compound.
