Styrofoam/EPS compactor is also known as a pint-size hydraulic compactor. It is used for processing the product and reusing the waste materials. Recycling waste materials are one of the best ways to make the products re-usable and significantly reduce the quantity of waste released in the environment. Burning of waste materials like foam, plastic, rubber and other waste products leads to air and soil pollution. Thus, recycling the products help in saving the environment and energy used.
Styrofoam compactor is a non-biodegradable polymer that efficiently compresses different types of foam including expanded polystyrene (EPS), expanded polyethylene (EPE), expanded polypropylene (EPP), extruded polystyrene (XPS), polystyrene paper (PSP), polyurethane (PUR) and polyisocyanurate (PIR) foam and reduces the cost of transportation.
Foam densifier is a specialized machine that compacts the material and reduces the cost of transportation, thereby offering a number of other incentives. Being light, rigid and highly durable, it turns out to be an excellent packaging material. The inert nature of the polymer along with the thermal and electrical insulation makes it a preferred choice for food, electronics and other packets for shipment
Foam densifier can be classified into two forms, one hot melt, and cold densifier. Let us take a look at them:
Hot melt densifier:
This type of machines uses heat to compress the foam and remove the air trapped in EPS or Styrofoam. The foam is shredded into small pieces and then the pieces are fed into heated parts. The foam can easily store and transported to the recycling facilities. Such machines help in reducing the volume ratio ranging 90 to 1.
This type of machine passes no heat to compress foam instead the foam is compressed pneumatically. The volume reduction ratio which is achieved by cold densifier is lower than the hot densifier and ranges from 80 to 1. However, the cold Styrofoam densifiers help in processing the foam faster as compared to the hot melt densifier.
