How Foam Density is Rated

All Foam is not Created Equal

Density, measured in pounds per cubic foot,  is the key property for determining flexible foam performance.

The firmness of the foam does not determine its quality, price or durability.
Density relates to the comfort, support and durability properties of the foam.
Adding cheaper foam additives or fillers can alter density. Additives are used to make a cushion feel heavier and more luxurious, or to improve the support, but they may have a negative effect on other foam properties, including tear strength, air flow and durability. Continue reading


Why EPS foam a better packaging material than paper?

When choosing packaging materials, the following factors must be taken into consideration: thermal insulation performance, shock absorbing ability and environmental impacts.
The most apparent advantage of EPS foam over the cardboard is that its insulation performance is better. During the same time of 10 minutes, the paper cup losts twice as much heat as that in a foam cup. To protect people’s hand from the hot beverages, the paper cups must be two-layered or use some kind of wrap. Hence, the paper containers are bigger and heavier.
On the other hand, it is reported that, based on the life cycle analysis, the energy consumption and environmental impacts of EPS foam packaging is better than cardboard packaging as is shown in the following pictures.
Comparison of EPS Foam and Cardboard Packagings

Polyurethane Foam Is Recyclable And Provides Environmental Benefits

Foam Is Recyclable And Provides Environmental Benefits Foam is recycled and provides environmental benefits compared to spring mattress units. Many materials are difficult to recycle. Some simply don’t produce a valuable recycled material. Others are difficult to collect and transport. But, flexible polyurethane foam is now being recycled and providing environmental benefits.

Up to 30 percent of all foam can become scrap after cutting and shaping foam in product fabrication. Without recycling this would be a costly disposal problem for foam manufacturers. However, with the development of practical end uses for scrap foam, almost every piece of scrap is recyclable. Continue reading

There’s no any CFC’s in PS foam

There’s no any CFC’s in PS foam“Foam” is generally known everywhere but in fact its’ meaning is so wide. According to translation “Foam” means, “expand” or “blow”. There are two kinds of EPS Foams:

1. Expandable Polystyrene(EPS) usually use as packaging for many kind of products such as television, electrical appliances, helmet, ice box, sheet foam and block foam for road construction. Continue reading

Processes of Constructing EPS foam

Processes of Constructing EPS foam | Foam Compactors for foam recyclingThe first step in the process of constructing EPS foam is puffing the EPS resin. The EPS foam resin is puffed when in the manufacturing process they are places in a closed chamber and uncovered to steam.

At this time the warmth from the steam causes the pentane gasoline contained within every bead to broaden, at which will not be unusual to see the foam filler broaden by as a lot as 30-35 instances the starting size. Continue reading

Curbside Foam Recycling Could Become Byproduct of Highland Park Effort

By Bob Susnjara

While foam recycling at a drop-off site in Highland Park has been deemed a success, the ultimate goal is for such a program to be accomplished with curbside collection, says the head of the Solid Waste Agency of Lake County.

Highland Park officials announced Friday that 4,417 pounds of foam was collected for recycling in one year at the city’s firearms training center on Half Day Road. The effort was sponsored by the solid waste agency and two businesses involved in polystyrene foam food packaging, Dart Container Corp. and Pactiv LLC. Continue reading

The Way To Make EPS Foam Filler

EPS Foam Beads | The Way To Make EPS Foam FillerThe puffing of EPS (expanded polystyrene) resin, creating the puffed polystyrene beads is step one in producing EPS Foam blocks. The EPS resin is puffed when in the manufacturing course of they’re places in a closed chamber and uncovered to steam. Continue reading

Marine Pollution By Foam

Plastic from urban runoff is the largest source of marine debris worldwide. The United Nations Environment Program estimated in 2006 that every square mile of ocean hosts 46,000 pieces of floating plastic.

Marine Pollution by Foam | Foam Compactors for Waste Foam ManagementPolystyrene foam presents unique management issues because of its lightweight nature, floatability, and likelihood to be blown from disposal sites even when disposed of properly. Continue reading

Make Props Out of EPS Foam

Authentic-looking props are essential to setting the scene in a theatrical production. Set designers create stage props out of a variety of materials, including one of the most common materials, expanded polystyrene (EPS).

Make Props Out of EPS FoamLightweight and versatile, EPS foam makes a good choice for set design. Once coated with sculpting products, EPS foam becomes a sturdy material that you can reuse. EPS will help you bring your production to life with realistic props that will fool the eye. Continue reading

What Are Urethane Foam Sheets

What are Urethane foam sheets | Foam compactorUrethane foam sheets are come in flexible sheets that are less than an inch thick, and are installed in homes and businesses to act as an insulative barrier which comprised of polymers linked by organic compounds called urethanes. Urethane foam sheets traditionally come in either two or three pound thicknesses.
