Foam densifier can compress foam board into dense ingots to supply reused material

Large foam boards have always been difficult to recycle. They are widely used in insulation panels, furniture packaging, and appliance protection, but because the material is lightweight and bulky, it takes up a lot of storage and transportation space. Although polystyrene foam can be recycled, much of it still ends up in landfills because collecting and processing large foam boards is often more complicated and costly than handling smaller foam packaging waste.

Foam board recycling mainly involves two common materials: EPS foam board and XPS foam board. Both belong to polystyrene (PS) foam, but they are produced using different manufacturing methods. EPS is made through a foaming process, while XPS is produced through extrusion technology. Even so, both materials can be fully recycled with foam densifier equipment. In many cases, foam boards are discarded simply because they are bulky and difficult to handle, or because suitable recycling equipment is not available.

Foam densifier has a remarkable effect on the heating, melting and recycling of EPS foam board or XPS foam board. Put the foam board into the GREENMAX foam densifier. First, the sharp knife in the crushing device will directly break the waste into small pieces , and then enter the heating device part for heating and melting, and finally extruded and cooled to become dense ingots, the compression ratio can reach 90:1.

Foam recycled through hot-melt technology usually has a much higher compression ratio, which also gives it a higher market value. In many cases, compressed foam ingots can be sold for several times the price of loose foam waste, making this one of the key advantages of GREENMAX foam densifiers. After processing, the recycled foam material is commonly blended with virgin material and reused in new manufacturing applications as a valuable recycled resource.

FAQ
How does foam densifier recycle foam boards?

A foam densifier crushes foam boards into smaller pieces, heats and melts the material, and then compresses it into dense ingots for easier storage and transportation.

What is the compression ratio of a foam densifier?

Depending on the material and machine model, the compression ratio can reach up to 90:1, significantly reducing foam waste volume.

What are recycled foam ingots used for?

Recycled foam ingots are often sold for granulating and can be blended with virgin plastic materials for manufacturing new plastic products.
