WebPolyethylene foams may be low-density or high-density foam. At the molecular level, the stages of the foaming process are gas dissolution, cell nucleation, cell growth, and cell stabilization. The primary raw materials for polyethylene foam production are polyethylene resins (LDPE or HDPE) and blowing agents. WebProduction of High Density Polyethylene via Slurry Process; via Solution Process; and via Gas Phase Process. In the gas phase process, ethene and hydrogen are combined, and the resulting mixture is passed over a Philips catalyst in a fixed bed reactor to finally achieve polymerisation reaction and produce High Density Polyethylene grains.
