Regarding the processed material there are two main types of polystyrene density-wise;
EPS = Expanded PolyStyrene:
most used in the range of: 10 - 50 g/l
EXPS or XPS = EXtruded PolyStyrene:
most used in the range of: 25 - 45 g/l
Polystyrene is a synthetic aromatic polymer made from the monomer styrene. Styrofoam is a trademarked brand of expanded polystyrene foam, used for thermal insulation and craft applications. In general, polystyrene refers to the polymer, while Styrofoam specifically refers to the foam product.
The density of thermocol or polystyrene is 1.64 g/cm3. it can vary due to the mass and volume of the object, the density usually ranges from 5kg/m3 to 12kg/m3.
The best glue for polystyrene foam is a solvent-based adhesive specifically designed for bonding foam materials.
Polystyrene is often sold in bulk on a m3 (cubic meter) price in Europe The cost is also effected by the density of the polystyrene. That is assuming your talking of expanded polystyrene foam, polystyrene is also available in hard plastic sheet form. dunno
One can purchase polystyrene foam at many home improvement stores, such as Home Depot and Lowes. Polystyrene foam expands after it is applied, so it is a great gap filler in home improvement.
The best type of glue for adhering polystyrene foam together is a solvent-based adhesive specifically designed for polystyrene.
The best adhesive for bonding polystyrene foam is a solvent-based adhesive specifically designed for use with foam materials.
The best techniques for bonding polystyrene foam using polystyrene foam glue are to apply the glue evenly on both surfaces, allow it to partially dry before joining the pieces, and apply pressure while the glue sets to create a strong bond.
Polystyrene foam, commonly known as Styrofoam, is made from a petroleum-based plastic called polystyrene. It is created by heating and extruding polystyrene pellets into a foam material that is lightweight and insulating.
Styrofoam is made up of extruded polystyrene foam. Extruded polystyrene foam is also used in models and crafts, specifically architectural models.The primary ingredient is benzene.
Expanded polystyrene (EPS) foam is similar to Styrofoam in terms of its lightweight and insulating properties. Other materials that are comparable include extruded polystyrene (XPS) foam and polyurethane foam.
