What are the various uses of Expanded Polystyrene or EPS?


Once accidentally discovered in Germany by Eduard Simon in 1839, the extremely light-weighted product created with polystyrene beads became much popular in the logistics industry. Gradually, the expanded polystyrene became popular in various sectors for its multifunctional uses and lightweight. The EPS foams are formed with only 5% plastic and 95% air. Various industries are associated with popular brands like ArmstrongBrands.com for their outstanding services they have to offer from shipping to logistics.

What is expanded polystyrene or EPS?

Abbreviated as EPS, the expanded polystyrene is nearly forty times the volume of the actual polystyrene granule which is indeed a matter to consider. Normally, the polystyrene is a solid thermoplastic kept in the room temperature. It is melted at a higher temperature and again re-solidifies for manufacturing the desired shapes and applications. The tiny particles of the polystyrene are prepared from the monomer styrene.

Various uses of polystyrene

It’s because of the multifaceted features and properties- the polystyrene foams have wider room to serve different industries per their individual requirements. The EPS forms are excellent for being extremely light weighted. Again, the thermal insulation property helps them in serving the requirements from logistics to shipping and more. The EPS foams have good damping properties which are why they are used in building industries and more.

So, we can get more of their uses in the following. Let’s have a quick look—


Companies like Armstrong Brands and more offer excellent packing solutions for consumer goods. They claim to offer the one-stop EPS foam products that are customized and reshaped per the client’s demands so that the products can be protected even when they have to travel a thousand miles by air or ship. By using the finest quality EPS foams, the companies ensure lightweight and compact packing which are two essential things to consider before shipping them. By using the 3d modeling software and prototype designs, the service providers go an extra mile in manufacturing and reshaping the molded foams.

Building and construction

EPS foams serve well in the building and construction industries. For its innate nature, the EPS is not prone to any chemical reactions. For this feature, the builders prefer using these foams in the constructions widely as they are not going to cause any hassle while coming in contact to the pests. They also have the cells closed but can absorb some water but will never form molds or rotting hassles during the post-construction phase. EPS is also durable and boasts on the longevity without expecting much maintenance. Thus, the EPS foams are used in forming the insulated walls, floors, and roofs of the buildings. These are also used during the construction of roads and railway tracks.

Other uses of the EPS foam

The EPS foams are best in stacking packed foods and other food items mainly shipped. These are used in manufacturing the children seats in the cars as well as the extra padding in the helmets.

For the light weighted feature different others, the expanded polystyrene foams are used in various industries.
