Styrofoam Blocks Los Angeles

The term Styrofoam receives plenty of interpretations in its usage in industries like railways, commercial buildings, and landscaping. Styrofoam refers to closed-cell EPS foam. People who do not understand the meaning use the name as a synonym of expanded EPS blocks. Lacking the proper sense of the name may leave you with a product that does not match the intended purpose.

Differences between Styrofoam and EPS foam blocks

Physical qualities

The many differences in their physical attributes include color, density, strength, and ability to withstand heavy loads. 

Styrofoam blocks are blue, while EPS blocks are white. The EPS blocks have a lightweight and heavy density, making them more durable and stronger for the long haul. Consequentially, EPS is has a higher demand and offers additional strength and ability to carry heavy loads. The permeability rating is higher than that of Styrofoam, resulting in better resistance against mold.

Environmental effect

The two materials have different amounts of recyclability. Styrofoam is not recyclable, and EPS has convenient recyclability. Expanded EPS has organic elements that lack harmful substances like CFCs and HCFs. While this factor gives it a better green rating, controversial discussions state that it may fall behind Styrofoam on the conservatism scale.

EPS takes longer to biodegrade than Styrofoam and is therefore apt to form litter in the outdoors. This situation makes it unfavorable for usage on building and landscapes next to the ocean, because it is a danger to marine life.


EPS is ideal for the construction of projects that need better resistance and durability. Its application includes stabilizing the soil, forming road banks, below-grade applications, and sheathing. It is also perfect for the development of insulation materials, landscaping features, and pools. 


EPS foam blocks perform better than styrofoam blocks in Los Angeles. This setup makes it ideal for use in longer-lasting projects. Styrofoam blocks in Los Angeles are excellent for temporary projects. 

Chemical reactions

EPS has an aromatic smell and forms a reduced barrier to oxygen and water. Styrofoam does not have a distinct aroma and has a better resistance against water and air. It is preferable in the creation of coolers, cushion materials, and coffee cups. The nature of EPS makes it useable in the production of transparent plastic, such as DVD cases and fridge containers.

Another uniqueness of Styrofoam is that it has moderate solubility in organic solvents, propellants, and cyanoacrylate.


EPS blocks cost less than the same amount of Styrofoam blocks.


Styrofoam is a product of extruded polystyrene, while foam blocks are products of expanded polystyrene. This case means that both materials arise from polystyrene resins but turn into sheets and blocks in different manners. 

The blowing agent that forms the final product leaves the beads quickly enough to create thousands of small cells full of air. The blowing agent that makes Styrofoam remains to be a part of the beads for an extended period; hence, it prevents and reduces the excessive flow of air through the material.

Styrofoam undergoes continuous extrusion to create closed-cell forms, while EPS passes through a process that molds beads and uses pressure and heat to hold them together.
