EPS Thorofoam Insulation

Detailed Description

Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behavior is exploited for extrusion (as in Styrofoam) and also for molding and vacuum forming, since it can be cast into molds with fine detail.

Polystyrene is waterproof thermoplastic foam which is an excellent sound and temperature insulation material. It comes in two types, expanded (EPS) and extruded (XEPS) also known as Styrofoam. The two types differ in performance ratings and cost. The more costly XEPS has an R-value of R-5.5 while EPS is R-4. Polystyrene insulation has a uniquely smooth surface which no other type of insulation Material possesses.

Typically the foam is created or cut into blocks, ideal for wall insulation. The foam is flammable and needs to be coated in a fireproofing chemical.

Polystyrene foams are good thermal insulators and are therefore often used as building insulation materials, such as in insulating concrete forms and structural insulated panel building systems. Grey polystyrene foam, incorporating graphite has superior insulation properties. They are also used for non-weight-bearing architectural structures (such as ornamental pillars). EPS foams also exhibit good damping properties; therefore it is used widely in packaging.

Expanded polystyrene (EPS)

Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. It is usually white and made of pre-expanded polystyrene beads. EPS is used for many applications in Thermal, Acoustic Insulation & packaging e.g. Chilled Water Pipe line, Tanks, Cold Rooms/Storage, Equipment insulation, trays, plates, bowls and fish boxes. Other uses include molded sheets for building insulation and packing material ("peanuts") for cushioning fragile items inside boxes. Sheets are commonly packaged as rigid panels

Due to its technical properties such as low weight, rigidity, and formability, EPS can be used in a wide range of different applications

Best results for Insulation are achieved for the temperature Range: -ve 40°C to +ve 40°C
