What is high density polystyrene used for?

What is high density polystyrene used for?

High Impact Polystyrene uses Thanks to its strength and durability, the thermoplastic is ideal for marketing purposes and is often used for Point of Sale displays, handling trays, and promotional signage. It can also be used for thermoformed machine housing and parts, model making and plastic toys.

What is the thickest styrofoam you can buy?

Can be cut to any thickness up to 32″ thick; Contact Us for details.

What is high density foam board?

A high-quality, cost-effective closed-cell PVC foam specially formulated to provide high physical properties. Engineered to be easy to work with, be weatherproof and deliver good insulation properties, Additionally, it has superior fire behavior.

What is the difference between polystyrene and high impact polystyrene?

General Purpose Polystyrene, also known as crystal-clear polystyrene, is fully transparent and rigid, and is widely used in food packaging applications or jewel cases. High Impact Polystyrene, on the other hand, is impact resistant at the cost of not being naturally clear or transparent.

What are the advantages of high impact polystyrene?

it is sturdy and durable with strong impact resistance. it is easily processed. it is easy to paint and glue. it has a relatively low cost.

What is EPS foam insulation?

Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material.

Is Styrofoam water resistant?

Styrofoam is mostly air, which is why it is so light. It is water resistant but not waterproof — it will absorb water over time in many applications.

Is polystyrene foam the same as Styrofoam?

The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that’s often used to make clear products like food packaging or lab equipment.

Is high density foam insulation waterproof?

It depends on the density of the foam. Open cell foam is not waterproof or water-resistant. In contrast, closed cell foam is water-resistant. However, only high-density closed cell foams are waterproof.

What is the density of Styrofoam?

1.05 g/cm3

Density 0.96–1.05 g/cm3
Melting point ~ 240 °C (464 °F; 513 K) For Isotactic Polystyrene
Boiling point 430 °C (806 °F; 703 K) and depolymerizes
Solubility in water Insoluble

How is Gpps made?

General-purpose Polystyrene, also known as GPPS is a substance prepared from styrene monomer polymer. It is a solid, transparent product and is manufactured by a suspension process. It is also known as crystal-clear polystyrene and is very different from high impact Polystyrene (HIPS).

Where to get Styrofoam blocks?

Have you ever wondered where artists and sculptors find the giant sculpting foam blocks to carve? Chances are, if you are on the east coast between Virginia and Maine you may be ordering your giant foam sculpting block from Insulation Company of America in Allentown, PA just north of Philadelphia.

What is high density EPS foam?

http://www.EPSFoamPro.com. Basically HD foam stands for High Density Foam. EPS Foam in Manufactured in Many Different Densities, and some EPS manufacturers produce their foam in 1 pound, 1.25, 1.5, 2 and 3 pound densities. If you place one cubic foot of EPS foam on a scale and it weighs 1 pound, then it is considered to be one pound density.

What is the your value of rigid insulation?

Traditional loose-fill insulation, such as fiberglass or cellulose , has an R value between R-2.0 and 3.5 per inch of thickness. Rigid insulation R value, by comparison, usually ranges from R-4.0 to 6.5, and may get as high as R-8.7, depending on the insulation material.

What is the your value of polystyrene?

Extruded Polystyrene Foam. XPS has an R value of 4.5 to 5.0 per inch of thickness. This is the product that I typically use to insulate basement walls. It’s reasonably priced, light weight and easy to use. This product is also used to insulate the outside of foundation walls and even under slabs.
