As the world-leading polystyrene processor and French leader on the EPS moulded item market, we simultaneously factor in performance and growth to always offer more sales expertise. In 30 years, we have developed our know-how in the various technologies associated not solely with packaging but also with the manufacture of technical parts.On the back of our expertise in processing expanded plastic resins, such as expanded polystyrene, we now provide services for particularly demanding industrial sectors.

The diversity of our production processes enables us to choose the best for your products.

The raw material

یونولت بسته بندی

Expandable polystyrene, our raw material, is manufactured in part by Knauf in Belgium. It is obtained by polymerising styrene and an expansion agent: pentane. In our factories, it undergoes pre-expansion, a decisive phase in the moulding process. Under the effect of steam, the expanded beads then grow by 50 times their original volume and develop a closed-cell structure made up of 98% air.

Block moulding

Block moulding makes it possible to manufacture parallelepipedal items. These “blocks” are subsequently machined in our cutting workshops to manufacture protective stays, decorative products or prototypes.

  • Dimensions: 1m x 1m x 6m (WxLxH)
  • Minimum density: 10 g/L

ITEM MOULDING

Equipped with over 240 presses, distributed throughout 40 production facilities, we deploy our closed-cell moulding expertise for the manufacture of items made of EPS (max.: 2000 x 1400cm, densities 18g/l – 60g/l)

Besides being customisable, our tools are “mobile” within our facilities. Their adaptability to a large number of machines makes it possible to envisage rapid transfer of production.

The diversity of our equipment (vacuum equipment, transfer and film complexing) allows us to adapt our production according to the complexity of your products.

Complexing helps enhance the mechanical behaviour of the closed-cell foam object, by increasing its rigidity and making it more watertight.

علی پور

Expanded Polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls. It is this closed cellular construction that gives EPS its remarkable characteristics.

EPS is produced in a wide range of densities providing a varying range of physical properties. These are matched to the various applications where the material is used to optimise its performance and strength.

Building and Construction


EPS is used widely in the building and construction

یونولیت industry. EPS is an inert material that does not rot and provides no nutritional benefits to vermin therefore does not attract pests such as rats or termites. Its strength, durability and lightweight nature makes it a versatile and popular building product. Applications include insulated panel systems for walls, roofs and floors as well as facades for both domestic and commercial buildings. It is also used as a void-forming fill material in civil engineering projects, as a lightweight fill in road and railway construction, and as floatation material in the construction of pontoons and marinas.

Packaging


Considerable quantities of EPS are also used in packaging applications. Its exceptional shock absorbing characteristics make it ideal for the storage and transport of fragile and expensive items such as electronic equipment, wines, chemicals and pharmaceutical products. The outstanding thermal insulation and moisture resistant properties of EPS enables freshness extension of perishable products such as produce and seafood. Moreover, its compression resistance means that EPS is ideal for stackable packaging goods. The majority of EPS packaging manufactured in Australia is used in the transport of fruit, vegetables and seafood. EPS packaging is used extensively for both the domestic and export market.

Other

EPS has a positive strength to weight ratio making it an effective and popular solution for the use in gliders, light and model planes and also surfboards.

When safety is paramount, EPS comes into its own. It is used in the manufacture of children’s car seats and cycling helmets, where its protective qualities such as strength and shock-absorbency are vital.

EPS also has applications in horticulture as seedling trays. Granulated EPS can also be added as a soil conditioner to promote aeration of the soil.

Is the 30-Year-Long Styrofoam War Nearing Its End?

علی پور

In 1987, a barge called Mobro 4000 departed Islip in New York’s Suffolk County loaded up with 3,100 tons of waste, a fair bit of which was Styrofoam containers. The barge was supposed to unload its undesirable cargo into a landfill in North Carolina, but that proved harder than expected. No one wanted the trash. Mobro barge ended up wandering the eastern seaboard for six months, dipped into the Caribbean, and even made it as far as Belize without finding a suitable dumpsite.

The fiasco drew media attention and ignited a national conversation about landfills, recycling, and the environment. Not surprisingly, Styrofoam emerged from this debate as the logical bad guy since it does not biodegrade and thus, it was argued, would crowd landfills and pollute our oceans. In 1988, New York’s Suffolk County enacted the first Styrofoam ban in the United States, but a plastics lobby quickly formed in response and succeeded in overturning the ban. Since then, similar bans have been put in place around the country—on Styrofoam, plastic bags and, most recently, plastic straws—resulting in years of litigations and millions of dollars worth of legal fees.

یونولیت بسته بندی

We’ve been stuck in the same debate for the past 30 years. Styrofoam is still here—but is that good or bad? Turns out, there’s no simple answer. And Styrofoam’s story is certainly complicated.

A Wonder Product or a Waste Nightmare?

First discovered in 1839 in Berlin, Styrofoam’s precursor—expanded polystyrene (EPS) foam—became immensely popular during World War II as an inexpensive building material for military aircrafts. Between 1939 and 1945, the rate of polystyrene production increased expotentially. In 1946 the Dow Chemical Company trademarked Styrofoam. In the process of trying to make polystyrene more flexible, Dow scientist Ray McIntire mixed together styrene and isobutene in a reactor and heated them. The result was extruded polystyrene foam, a strong material that is moisture resistant and composed of 98 percent air—so incredibly lightweight and buoyant that it was considered a wonder product. Its low cost and ease of production catapulted Styrofoam into our lives. From energy efficient building insulation to surfboards, and from soilless hydroponic gardening to airplane construction, Styrofoam was heralded as the wave of the future—until the environmental issues came up.

علی پور

EPS or as many know by The Dow Chemical Company's trademarked name, STYROFOAM, is an extremely lightweight product that is made of expanded polystyrene beads. Originally discovered by Eduard Simon in 1839 in Germany by accident, EPS foam is more than 95% air and only about 5% plastic.

Small solid plastic particles of polystyrene are made from the monomer styrene. Polystyrene is normally a solid at room temperature that can be melted at a higher temperature and re-solidified for desired applications. The expanded version of polystyrene is about forty times the volume of the original polystyrene granule.

Uses of Polystyrene

Polystyrene foams are used for a variety of applications because of its excellent set of properties including good thermal insulation, good damping properties and being extremely light weight. From being used as building materials to white foam packaging, expanded polystyrene has a wide range of end-use applications. In fact, many surfboards now use EPS as the foam core.

Invention of Polystyrene and Styrofoam

يکشنبه 25 آذر 1397

علی پور

Polystyrene is a strong plastic created from erethylene and benzine. It can be injected, extruded or blow molded. This makes it a very useful and versatile manufacturing material.

Most of us recognize polystyrene in the form of styrofoam used for beverage cups and packaging peanuts. However, polystyrene is also used as a building material, with electrical appliances (light switches and plates) and in other household items.

Eduard Simon & Hermann Staudinger Polymer Research

German apothecary Eduard Simon discovered polystyrene in 1839 when he isolated the substance from natural resin. However, he did not know what he had discovered. It took another organic chemist named Hermann Staudinger to realize that Simon's discovery, comprised of long chains of styrene molecules, was a plastic polymer.

In 1922, Staudinger published his theories on polymers. They stated that natural rubbers were made up of long repetitive chains of monomers that gave rubber its elasticity. He went on to write that the materials manufactured by the thermal processing of styrene were similar to rubber. They were the high polymers, including polystyrene. In 1953, Staudinger won the Nobel Prize for Chemistry for his research.

BASF Commercial Use of Polystyrene

Badische Anilin & Soda-Fabrik or BASF was founded in 1861. BASF has a long history of being innovative due to having invented synthetic coal tar dyes, ammonia, nitrogenous fertilizers as well as developing polystyrene, PVC, magnetic tape and synthetic rubber.

یونولیت

In 1930, the scientists at BASF developed a way to commercially manufacture polystyrene. A company called I.G. Farben is often listed as the developer of polystyrene because BASF was under trust to I G. Farben in 1930. In 1937, the Dow Chemical company introduced polystyrene products to the U.S. market.

What we commonly call styrofoam, is actually the most recognizable form of foam polystyrene packaging. Styrofoam is the trademark of the Dow Chemical Company while the technical name of the product is foamed polystyrene.

Most foam #6 products can be identified by the resin identification code stamped on the material. Types of foam #6 are often mistakenly referred to as Styrofoam®, which is a registered trademark of the Dow Chemical Company for extruded polystyrene foam made for thermal insulation and craft applications. The types of foam products that are accepted can vary between processing facilities. For example, many processors do not accept colored foam or foam that has been treated with flame retardants. Check with your recycling facility to confirm the types of foam that are accepted.

Foam cups and food service products

FPO - Foam CupsFoam #6 food service containers include drink cups, food trays and clamshell containers. Food service foam containers must be in recyclable condition. Coffee and soda cups do not need to be rinsed; however, containers used for food need to be wiped or rinsed.

Recycling is offered curbside in some communities. Some restaurants and other businesses collect foam cups for recycling by mail. In addition, some school districts have started recycling programs for foam #6 lunch trays and containers.


Foam packing peanuts

FPO - Foam PeanutsPackaging peanuts are made with a variety of materials. Some, but not all, packing peanuts carry the #6 recycling symbol. When combined with foam #6 products, non-EPS packing peanuts are a contaminant. For that reason, packing peanuts should not be commingled with other foam recycling.

یونولیت بسته بندی

The best way to recycle foam packing peanuts is to reuse them or donate them for reuse. Many local pack and ship stores gladly accept foam packing peanuts free of charge. Some cities also collect them to reuse or resell. Please contact your local post office or parcel service to verify if they accept packaging peanuts for reuse.

Excessive rainfall led to the embankment of Highway 260 near Durango to collapse. Additionally, in general, the winding roadways through mountain passes are fraught with freeze-thaw cycles, eventually leading to road and supporting embankment failure. The above picture is a snippet from a video explaining a Colorado project.

In our next article, we’ll introduce you to the largest project using EPS Geofoam was in Salt Lake City, Utah on Highway 15. The 17 miles of government mandated road project is to date still the largest Geofoam project in the USA. The reason the government mandated the work was in preparation for the 2002 Olympics held there. Having the ability to manage a massive influx of visitors proved to be crucial to the success of the Winter Olympics of that year. Within the 2015 article, there is a link to a fascinating video of the project.
