STYRO EPS (Expanded Polystyrene) is a closed cell, snow white, lightweight, resilient, foamed plastic composed of hydrocarbon and atoms. STYRO EPS has a compressive strength of 50-270 KPA, which meets the requirements of all types of construction applications.

STYRO EPS can be molded to meet specific application requirements such as roofs, walls, and foundations. STYRO EPS has a successful history of efficient use in industrial, commercial, cold storage, and residential construction. While energy efficiency and cost effectiveness have long been primary design considerations, architects have made STYRO EPS a dominant thermal insulator. Major uses of STYRO EPS are in heat insulation, packaging and decoration.

Worldwide STYRO EPS (Expanded Polystyrene) is also popularly known by the following generic names: STYROFOAM, STYROPOR, RIGIFOAM, FILLIN, GEOFOAM & THERMOCOLE.

Polystyrene, sometimes abbreviated as “PS”, is an aromatic polymer made from the chemical styrene, a liquid hydrocarbon that is commercially manufactured from petroleum by the chemical industry. Polystyrene is a thermoplastic substance that normally exists in solid state at room temperature, but melts if heated (for molding or extrusion), and becomes solid again when cooled. Polystyrene can be recycled, and has the number “6″ as its recycling symbol.

Polystyrene is one of the most widely used kinds of plastic. Pure solid polystyrene is a colorless, hard plastic with limited flexibility. It can be cast into molds with fine detail. Polystyrene can be transparent or can be made to take on various colors. Solid polystyrene is used, for example, in disposable cutlery, plastic models, CD and DVD cases, and smoke detector housings. Products made from foamed polystyrene are nearly ubiquitous, for example: packing materials, insulation, and foam drinks cups. Discarded polystyrene, which does not biodegrade, is often abundant in the outdoor environment, particularly along shores and waterways.

Polystyrene is commonly produced in three forms: extruded polystyrene, expanded polystyrene foam, and extruded polystyrene foam, each with a variety of applications.

Extruded polystyrene
Extruded polystyrene (PS) is economical, and is used for producing plastic model assembly kits, plastic cutlery, CD “jewel” cases, smoke detector housings, license plate frames, and many other objects where a fairly rigid, economical plastic is desired. Production methods include stamping and injection molding.

Foams
Polystyrene foams are good thermal insulators, and are therefore often used as building insulation materials, such as in structural insulated panel building systems.
They are also used for non-weight-bearing architectural structures (such as ornamental pillars).

Expanded polystyrene foam
Expanded polystyrene foam (EPS) is usually white and made of expanded polystyrene beads. Familiar uses include packing “peanuts” and molded packing material for cushioning fragile items inside boxes.

Extruded polystyrene foam
Extruded polystyrene foam (XPS) has air inclusions which gives it moderate flexibility, low density, and low thermal conductivity.

R-Value (thermal resistance) indicates the insulating power of an insulation material. The higher the R-value, the greater the insulating power (i.e more energy saving).

YES, it has a LONG-TERM INSULATION VALUE. STYRO EPS R-value doesn’t deteriorate over time. As a result, the thermal resistance stays consistently constant throughout its age ( R-value).

It can be used for both cold and heat insulation where the application temperature ranges from -110 Degrees °C to +110 Degrees °C

Absolutely all STYRO EPS products can be painted with a water based paint, however, oil based paints can also be applied if STYRO EPS surface is coated with a special hard coating. STYRO can be supplied with hard coating on demand. (Please refer to the Do’s and Don’t page for more details).

Yes , STYRO EPS can be bonded together with Super Styro Stick (SSS) special glue. This special glue is manufactured and supplied by STYRO. (Please refer to the SSS glue page for more info).

Several tests and studies proved that STYRO EPS insulation material installed in well-constructed roofs do not absorb appreciable moisture, even under conditions of prolonged, cold, and damp winters. The small amount of moisture absorbtion (an average of 0.2% by weight) has little or no effect on the compressive or flexural strength. STYRO EPS insulation retains between 95% and 97% of its thermal efficiency.

Though STYRO EPS has low water vapor transmission, STYRO EPS is not a vapor barrier. Rather, it “breathes”, and therefore needs no costly venting unlike some other relatively impermeable insulation materials, which could otherwise trap moisture within walls and roof assemblies.

Though STYRO EPS provides a high level of moisture resistance and breathability, it is recommended to be laminated with Alu. Foil, Foil Scrim Kraft (FSK), or LDPE sheet. Otherwise, a non-solvent based vapor barrier adhesive can be applied  as a coating on EPS.

From the engineering and economical aspects, it is often advisable and even essential to protect pipelines from heat losses and condensation. Low thermal conductivity, low permeability to water vapor, low water absorption, high dimensional stability, good mechanical strength, and protection from fire hazards are all aspects that constitute the ideal insulating material. EPS expanded polystyrene pipe section completely incorporates all these aspects, and is therefore particularly effective.

If EPS pipe sections get mechanically damaged during fixing or installation, the damage will be localized and water will not spread to the remainder of the insulation, unlike with most of the other material. This great advantage is due to the fact that EPS pipe sections have a completely closed cell structure.

EPS pipe section does not support infection or pest life and is unaffected by fungi and bacteria, making it the ideal choice for pipes operating in areas such as food processing, etc., where the highest levels of hygiene are required.

EPS pipe sections are manufactured on “Made to Order Basis” according to the customer’s sizes and specifications. It can be cutwith Shiplap joints and Tongue & Groove arrangement with the aid of High-Tech CAD / CAM – CNC Machines. Normally EPS Pipe sections are cut in to two halves with readily wrapped FRK facing (Foil Reinforced Kraft paper) in order to simplify the installation works at the sites.

It is indeed a fire-retardant, self-extinguishing material. All STYRO EPS products that are used in the construction industry are compliant with the following fire properties:

• Oxygen Index ( OI) by 24 % of its total volume (minimum).
• Smoke index : 0 – 450
• Flame Spread Index 26 – 75; (Class B) (Please refer to the FIRE retardant page for more details).

Like many other construction materials, non-flame retardant STYRO EPS is combustible. It should not be left exposed to flame or other ignition sources. STYRO EPS insulation should be covered with a thermal barrier or otherwise installed in accordance with applicable building code requirements. (Please refer to the FIRE retardant page for more details).

STYRO EPS comprises from 95% air and its unique resilient property gives excellent Sound & Acoustic Insulation properties. It’s dynamic stiffness ranges from 43-46 MN/M3 at a frequency of 74 to 91 HZ.

Absolutely NOT. STYRO insulation doesn’t contain Ozone Depleting Chlorofluorocarbons (CFCs), or Hydro chlorofluorocarbons (HCFCs).

STYRO EPS insulation is an inert, organic material produced from petroleum and natural gas by-products. STYRO EPS insulation does not contain ozone depleting chlorofluorocarbons (Clefts) or hydro chlorofluorocarbons (HCFCs). It is manufactured with Pentane as a blowing agent. It provides no nutritive value to plants, animals or micro-organisms. It will not rot, and is highly resistant to mildew. (Please refer to the Environment page for more details).

YES, STYRO EPS is 100 % recyclable. After its original life as an insulator, STYRO EPS could be recycled into a variety of consumer products. Many STYRO EPS converters have been reprocessing their own in-plant scrap for many years. An infrastructure for the collection of STYRO EPS is being developed, making it possible to produce products containing post-consumer recycled STYRO EPS materials.

The products of complete combustion are carbon dioxide, water vapor, and trace quantities of nonhazardous ash; similar by-products are produced when wood is burned. When land filled, STYRO EPS does not biodegrade. It will not create methane gas or materials known to be harmful to air quality and ground water. (Please refer to the Recycling page for more details).

Perm is a traditional unit of water vapor permeability, that is the ability of a material to permit the passage of water vapor. If we want to keep things dry, we wrap them in something having low permeability. A material has a permeability of one perm if it allows transmission of one grain of water vapor per square foot of area per inch of mercury (in Hg) of pressure difference per hour.

Perm inch is a traditional unit of water vapor Permeance. The perm value (see above) does not depend on the thickness of the material used as a water barrier. The permeance is the product of the perm value and the thickness, measured in inches.

The amount of water vapor passing through a given area of a plastic sheet or film in a given time, when the sheet or film is maintained at a constant temperature and when its faces are exposed to certain different relative humidity. The result is usually expressed as grams per 24 hours per square meter.

Permeability is the water vapor transmission of a homogeneous material under unit vapor pressure difference between two specific surfaces, per unit thickness. Permeability is important for specifying insulation materials.

Permeance is the water vapor transmission of a specific sample under unit vapor pressure difference between two specific surfaces.

YES, Petroleum-based solvents or its vapors can harm STYRO EPS. Care should be taken to protect STYRO EPS from those solvents or its vapors. (Please refer to the  Do’s & Don’t page for more details).

Yes, Prolonged exposure to direct sunlight will cause slight discoloration and forms yellowish skin on  top of  STYRO EPS insulation. This occurs due to UV sun rays, and is called  ULTRAVIOLET DEGRADATION. STYRO EPS should be protected with a light-colored opaque LDPE film or Tarpaulin sheets in case it is stored under direct sun light.

Generally, the quality of Insulation materials is  evaluated  based on the  Physical and Mechanical properties of these materials. STYRO EPS is the  only unique material meeting and exceeding  all  the requirements of insulation properties such as  thermal conductivity (Lamda vale (λ) or K value), thermal resistance (R value), compressive strength, water absorption, flammability, flexural strength, dimensional stability, etc.
