Sub-Product

Polyolefin Elastomers have a density of 0.85 to 0.88-0.886 g/cm³ (depending on the source) and a Melting Temperature from 35 to approximately 80°C. They are mostly Copolymers of Ethylene and 1-Butene since higher Linear Alpha-Olefins are required in too high concentration in the Copolymer to decrease the Density below 0.88 g/cm³. According to the Scientific Literature, a POE with a density of 0.87 g/cm³ requires about 50 wt-% each of Ethylene and 1-Butene.
