EPE FOAM’S PROPERTIES AND PROCESSING METHOD

EPE foam, or Expanded Polyethylene foam, is one of the most widely used plastics in production. What is polyethylene foam? It is a thermoplastic resin, which means that it can be melted by heating and cooled to form different shapes and objects.

EPE foam is a harmless plastic and has no taste or odour.

It is a very popular material for packaging goods as it is light in weight and flexible. It has the ability to absorb shock and provide good cushioning to delicate objects.

EPE has a high weight to strength ratio and high thermal resistance. It can be heated and melted multiple times, and reshaped into other new objects due to the high EPE foam temperature range.

EPE foam is resistant to water, oils, and many chemicals. It is also a very good insulating material. EPE is available in different densities, according to its application or purpose.

How Is EPE Foam Made?

As with most types of foam such as expanded polypropylene foam (EPP foam), expanded polyethylene (EPE foam), is manufactured by the application of high pressure, heat, as well as a blowing agent in a pressurized chamber called an autoclave.

The molten foaming polyethylene material is then made into small plastic beads in a machine that uses water to cool and form the beads.

The resultant plastic beads are used as feed material and injected into specialized moulds under high heat and pressure to force the beads to melt and take the shape of the mould.

The manufacturing process of EPE foam is pretty straightforward, and mostly involves the use of high temperatures and pressures in a sealed and pressurized container.

The leftover EPE material that is in the form of beads or defective pieces, or even material that has seeped through the material, can be collected and fed back into the machine to produce whole new pieces.

This is how to make polyethylene foam and is the principle behind the recycling of EPE foam material as well.

How is EPE Processed?

EPE is usually processed by cutting. And usually, customers require the EPE foam to be customized to a certain size and shape. This could be when they need to tightly pack some objects and the EPE must be cut in the form of the object.

For the cutting machine, it needs revolving blade or saw blade to cut special shapes. Or if customers like it to be simple sheet, it needs Horizontal or Vertical Blade to slice.

This Horizontal cutter could slice EPE foam from blocks to EPE sheet for package using.

This CNC Revolving Blade Cutting machine could cut the foam block into EPE roll and pipes with curve line cutting method. You just make a draw as what you want to cut in computer, then through operate our control cabinet. Then the machine would automatically finish the cutting after operating the machine
