Flexible Polyurethane Foam

Polyurethane Foam Recycling is Viable

The opportunity to generate additional revenues while eliminating costly waste removal has caught the attention of many home furnishings manufacturers, foam fabricators, carpet installers and other converts of flexible polyurethane foam. An easy product to recycle, flexible polyurethane foam scrap is now generating revenue for many end-users. The flexible polyurethane foam industry has made great strides in technology and end-use applications to address waste problems. By providing a “snapshot” of the opportunities for recycling in 1994, this bulletin is intended to assist manufacturers, production engineers, distributors, retailers, carpet installers, and others in the position to recover flexible polyurethane scrap. The following information examines the economic and environmental value of recovering and reusing scrap foam, with information on how your scrap can be used to generate revenue, offset raw material cost, and alleviate solid waste deposal problems.

Waste To Waves Recycling Program Gives Foam A Second, Ocean-Friendlier Life

Holiday shopping is upon us, and whether they do it in the stores or online, Americans are going to buy an absurd number of appliances, electronics, gizmos and gadgets in the run-up to Christmas.

With those gifts will come millions of pounds of packaging. While the cardboard box encasing your flat screens and Vitamixes typically can be recycled, the protective packaging foam (commonly known as “styrofoam”) that keeps those goodies snug usually can’t. As a result, most foam ends up in a landfill or, even worse, in the ocean.

Michael Stewart, co-founder of Sustainable Surf (a San Francisco nonprofit), discovered this sad reality over years of participating in California beach clean ups. Tired of seeing this type of plastic trash in and around the ocean, Stewart and Sustainable Surf’s other co-founder Kevin Whilden started the Waste to Wavesprogram, which aims to recycle styrofoam packaging back into new products — most notably, surfboards.

Polyurethane Foam Compactor for Compacting Refrigerators Foam

Application of Polyurethane Foam Compactor

Polyurethane foam compactor is mainly used in electric appliances recycling center that has tons of rigid PU foam from dissembled refrigerators. Another source of rigid PU foam is teared down workshops that made of sandwich panels.

How the Polyurethane Foam Compactor Works

Operator throws PU scraps into the machine hopper. The pre-breaker breaks the foam blocks into smaller flakes. An auger compactor presses the foam into compacted logs. Operator stacks the logs onto pallets.

Features of Polyurethane Foam Compactor

* Compacted PU foam blocks by ratio of 16:1 to 20:1;

* Achieves the capacity in the range of 200 kg/h to 500 kg/h;

* Equip with a pre-crusher;

* Cooling device so as to avoid polyurethane foam melting;

* Nitrogen filling mouth. Dilution of flammable gas inside, meanwhile dissipation of heat;

* Two exhaust ports. To exhaust flammable gas, which will hinder the PU foam forming;

* Customization for options of different feeding length, width.

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

COMPARISON BETWEEN EPS FOAM AND PAPER PACKAGINGS

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.

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
