Industrial plastic granulator labeled PWH-300 by Polymix, with a large hopper, control panel, safety switches, and output chute, used for processing plastic materials. The PWH-300 is engineered to deliver efficient size reduction and is fully compatible with PolyWiz Better Densifiers for optimized downstream processing.

PWH-300 Heavy Duty Thermal Styrofoam Densifier

For operations managing large amounts of foam, the PWH-300 combines processing capacity of up to 300 pounds per hour with a larger hopper for bulkier material. Keep your foam waste moving with a machine built for demanding workloads.

Industrial plastic shredder machine with a large feeding hopper labeled PWH-150, control panel, exposed wiring, and mounted components, designed for processing or recycling materials such as styrofoam when paired with densifiers or PolyWiz systems.

PWH-150 Light Duty Thermal Styrofoam Densifier

The PWH-150 delivers efficient foam densification in a more compact, light-duty machine. Ideal for operations with smaller waste volumes, it reduces foam by up to 90:1 and creates sellable purge blocks, helping your business recover value from its waste.

Get to Know Our Thermal Densifiers

Better Densifiers offers American-made PolyWiz thermal densifiers that shred and heat clean, dry foam, then extrude it as dense purge. That material can be formed into blocks and sold as a commodity.

For businesses handling foam in volume, the process not only reduces the space needed to manage waste, but also creates an opportunity to recover value from material they currently pay to dispose of.

Watch our overview to learn more about the equipment and its benefits for your operation.

Reduce the Cost and Volume of Foam Waste

Loose foam can fill storage areas and waste containers long before it adds much weight. Our thermal foam densifiers process clean, dry EPS, EPE, and EPP, reducing foam volume by up to 90:1. The resulting dense material is easier to store and transport—and can be formed into blocks for sale.
