Extruded polystyrene foam (XPS) also known as blue board or pink board comes in many different thicknesses and edge profiles. This insulation board is probably one of the most widely used foam board insulation products in the residential construction industry. XPS has an R value of 4.5 to 5.0 per inch of thickness.

Is polystyrene foam and Styrofoam the same thing?

Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam, or XPS. This foam is also referred to as “Blue Board” and is used for building insulation, thermal insulation and water barriers. Styrofoam is made out of styrene which is a petroleum-based product.

How strong is expanded polystyrene?

Electrical Properties – The dielectric strength of EPS is approximately 2KV/mm. Its dielectric constant measured in the frequency range of 100-400 MHZ and at gross densities from 20-40 kg/m3 lies between 1.02-1.04.

Is Expanded polystyrene the same as extruded?

Expanded polystyrene is a type of foam made from polystyrene. It is a lightweight, rigid and closed cell insulation. Extruded polystyrene is another form of foam made from polystyrene. The trademark name for this product is Styrofoam (by The Dow Chemical Company).

How do you make polystyrene foam at home?

Things You’ll Need

1. 2 tsp. borax.
2. 1/2 cup water.
3. 1/4 cup Elmer’s glue.
4. 1/4 cup water.
5. Air-tight plastic bag, gallon size.
6. 2/3 cups micro-beads (1mm in diameter)
7. 1 cup 1/8-inch bean bag filler beads.

Is polystyrene hard or soft?

Polystyrene is a versatile plastic used to make a wide variety of consumer products. As a hard, solid plastic, it is often used in products that require clarity, such as food packaging and laboratory ware.

Can I paint extruded polystyrene?

You can paint polystyrene foam or expanded polystyrene beads using a waterborne paint to protect it from solvent attack by subsequent coats of paint. After the polystyrene is completely covered, you can over-coat it using a conventional paint, if need be.

How to dispose of expanded polystyrene?

Expanded polystyrene should be placed in the waste bin. Polystyrene is also sometimes used for other food packaging like multi-pack yoghurts. Some local authorities accept it in recycling collections although it is unlikely to actually be recycled. You can check with your council if they accept it.

What is expanded polystyrene used for?

Polystyrene Foam. Polystyrene PS foam or expanded polystyrene as its more often referred to, is mainly used within the packaging industry, used as a high impact packaging solution to protect a large range of products from damage during transport or storage.

Why is polystyrene foam a good insulator?

The polystyrene foam Styrofoam is made of trapped air bubbles that prevent heat energy from flowing through it. This prevents heat loss, making Styrofoam an excellent insulator.

Is polystyrene foam a good insulator?

Polystyrene is a great thermal insulator, and can achieve excellent R value ratings at a given thickness for EPS , and even higher ratings for XPS. XPS polystyrene foam is more effective due to its dense structure and excellent moisture resistance.
