Having both a low molecular weight and a low modulus, LMPO is Idemitsu's newest polyolefin. The low melting point of our LMPO, short for low molecular weight and low modulus polyolefin, along with its range of viscosities, make this advanced polyolefin an ideal choice for hot-melt adhesives, resin modifiers, elastics and pigment-dispersing agents, as well as a range of other industrial applications. Its high heat-stability, coupled with its low melt-viscosity, solubility, and compatibility with polypropylene are all commercially desirable properties of our LMPO. Furthermore, Idemitsu's LMPO was perfected to be both colorless and transparent, adding valuable versatility to our formulation.
Another advanced feature of LMPO is the soft polyolefin characteristic, making it an ideal choice for displaying low crystal characteristics. Despite the polypropylene homopolymer present, LMPO employs a metallocene catalyst unique to Idemitsu's range of technologies that controls the stereoregularity of the polymer molecule.
