The first thing that is thought about when we talk about physical foaming are the expandable, low density foamed products made of polymers such as EPS, XPS or even other modified commodity polymers such as EPP or EPE.

With the physical foaming technology of MEAF, we do achieve a significant density reduction (up to 50%) yet the process itself significantly differs from the above mentioned products. The main difference with the expandable technology is that the physical foaming technology adds an environmental friendly blowing agent, N₂, into the polymer melt, thereby creating a micro-cellular structure the moment it leaves the die head, which in return causes the density reduction.

The microcellular structure decreases the density of the sheet without compromising on mechanical strength and top load properties. This foamed sheet produced by the MEAF sheet extrusion line can be utilised in packaging solutions (such as meat trays, clamshells or cups for hot fill) but also in industrial and/or electronic applications (such as car interiors, television screens and backlighting).
