EPE Foam Extrusion Line

In the production process of EPE foam or expanded polyethylene faom packaging materials, physical foaming is used instead of chemical foaming. Currently, the most common foaming is using butane gas foaming. The principle of foaming is to use butane gas to be liquid in the jar, and then to gasify instantaneously when extruding from the foaming head. Because the foaming of EPE resin is the result of the physical foaming agent changing from liquid to gas, The second , foaming agent is required to be colorless, odorless, non-toxic, non-corrosive, no residue is left in the polymer after foaming, low permeability in the polyethylene melt, low vapor pressure at room temperature, high volatility, molecular weight Low density and high density. The gas cost per unit volume is low. It can be dissolved in polyethylene in the extruded state. When the temperature and pressure are increased, the amount of solubility will increase. It is easy to make the plastic foam molded into a foam with low density.
