9/9/2018 · The key difference between expanded and extruded polystyrene is that we produce expanded polystyrene (or EPS) from solid beads of polystyrene while we produce extruded polystyrene (or XPS) from solid polystyrene crystals. Expanded polystyrene is a type of foam made from polystyrene. It is a lightweight, rigid and closed cell insulation.
Expanded vs. Extruded Polystyrene XPS & EPS Differentiators It is commonly understood that XPS offers more initial R-value per inch than EPS but because of its lower cost, EPS offers more R.
4/1/2020 · What is Extruded Polystyrene or XPS Polystyrene Foam? Extruded Polystyrene (XPS), is manufactured via an extrusion process where plastic resin and other additives are combined and extruded through a die. The extruded foam then cools and expands into its final shape. Extruded Polystyrene Foam Cell Structure. Insulating Properties of XPS Foam, 8/27/2020 · Densities are available at 1.0, 1.25, 1.5, and 2.0 lb/ft3. The large EPS blocks can be fabricated per specification to form insulation boards, blocks, or customized shapes for the roofing, insulated metal panels, and packaging industries. Extruded Polystyrene . XPS foam is manufactured from solid polystyrene crystals.
2 lb nominal density EPS (expanded polystyrene) has become a very popular alternative to extruded polystyrene for under slab and perimeter foundation wall insulation. The 2 lb EPS is available in any thickness, not just 1? increments and is more economical than extruded polystyrene. It has the same 25 psi compression strength as extruded polystyrene.

Expanded Polystyrene (EPS Foam): Uses, Structure & Properties, Polystyrene Panels : Should You Choose Expanded or …
Expanded Polystyrene (EPS Foam): Uses, Structure & Properties, 11/2/2017 · The Difference between Expanded Polystyrene and Extruded Polystyrene The main difference between these two materials lies in their density. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. on average for XPS vs. 0.93 lbs. for EPS).
EPS . EPS is made from expandable grade polystyrene . Expansion of the beads is achieved by virtue of pentane gas, a blowing agent, which is entrapped in the expandable beads. The heat from the steam in the pre-expansion phase causes the gas to expand, forming perfectly closed cells of EPS . For more information on EPS check out our Isolite …
1/18/2018 · Expanded Polystyrene Insulation, more commonly referred to as EPS , is a closed cell insulation that has been around since the 1950s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material. Expanded polystyrene is very versatile because it can be molded and cut into different …
XPS is often confused with EPS. EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins. However, difference lies in their manufacturing process.
