EPS (expanded polystyrene) is also known under other brand names – such as Styrofoam – It is insulative and protective and is used for a wide number of applications the most predominant is packaging. AS much as 98% of EPS can be air.
EPS (expanded polystyrene) is not biodegradable and when not compressed it often ends in landfill where the light, but expansive material creates significant environmental problems.
Different kinds of EPS
EPS comes in many different qualities depending on the application and manufacturer. Density, fire retardants and the shape of the material are some variables.
Density
We have seen EPS with a density from 10 grams per litre up to 100 grams per litre. Most types are between 20-35 grams per litre. The density particularly affects the compactor’s capacity per hour and whether a pre-crusher with larger motor as accessory is required.
Fire retardants
There are some types of EPS that contain different types of fire retardants, particularly in the electronics industry. Fire retardants increase the risk of the material melting during the process. Heat is required to make the compacted block stick together. But in contrast to other manufacturers our EPS compactors, do not add heat add heat to the process. The EPS material creates the required heat itself through friction.
