Frequently Asked Questions

What is EPS and what is it used for?

EPS stands for Expanded Polystyrene. This lightweight plastic material has a closed cellular construction of small hollow spherical balls, giving EPS remarkable characteristics and the ability to be used in various applications.

We manufacture products ranging from packaging for fresh produce (fruit, vegetables, seafood) through to a wide variety of building and construction applications, including insulated sandwich panels, domestic wall cladding systems, and under slab void filler pods.


How can a house reduce C02 emissions?

Houses that use EPS Waffle Pods in slab construction, use an average of 30% less concrete than conventional slabs, reducing Co2 emissions, and taking less time to build. Houses that use EPS for insulation, require significantly less energy to maintain comfortable temperatures. With EPS, you can build and live with less.

How effective is EPS insulation?

EPS thermal properties have proven to be extremely efficient. The cellular structure of EPS is 98% air and 2% polystyrene. It has superior stability and does not deteriorate over time, therefore delivering a life-long value.


Can you cut polystyrene to my requirement?

In most cases, yes, if you can provide us a drawing, sketch, and/or size we can provide you with a guide or even costs to cut to your requirement.

What does Polystyrene have to do with vaccines and organs?

Medical and pharmaceutical products demand protection and reliability. This is crucial for transporting materials worldwide, as seen recently with the COVID-19 vaccine. Nationally, Polyfoam provides over a million products per year to the science and medical industries. The superior insulation properties of EPS, keep vital organs, medicines and vaccines at a stable temperature during transit.

How do EPS products reduce food waste?

Over 30% by weight of Australian domestic garbage is wasted food. EPS packaging extends the life of landfills by keeping food fresh at the correct temperature for longer, thereby helping reduce food spoilage for a longer period.

Refrigerated transport can assist but offers no protection before loading, or after unloading. Breaks in cold chain distribution are detrimental to fresh produce and aquaculture and are one of the largest causes of food spoilage. EPS ice boxes protect food from farm to table, significantly reducing the environmental and financial impact of food wastage.


What is Airpop?

Airpop is another name for Expanded Polystyrene foam or EPS.

Where are you based?

The Polyfoam Group operates facilities in Melbourne, Sydney, Brisbane and Hobart, with joint venture operations in Adelaide.

Do you sell to the public?

Yes. We are a wholesale manufacturer, but we do sell many items to the public. Minimum quantities apply to our products.

How do I get a price for a product?

Contact your local office by phone or email with the product detail you need. We will be happy to provide you with more detail.

How long will a polystyrene box keep my item cool/warm for?

This is not something that can be easily answered as there are a lot factors to consider. Expanded Polystyrene is an excellent insulator and one of the cheapest options available to insulate your valuable cargo.

Is the website information up to date?

We endeavour to keep all information as accurate and up to date as possible. We ask that you confirm any particular information with the appropriate location. Note that all sizing given is subject to variation, if this is critical we ask that you obtain a sample from us, by contacting your nearest location or by contacting us.


How is EPS 100% recyclable?

EPS is recyclable at many stages of its life cycle. All EPS waste and clean, used material can be reprocessed and made into recycled EPS products including bike helmets, CD cassettes, coat hangers, synthetic timber, and more.

Is EPS bad for the environment?

EPS is resource efficient. The manufacturing uses little energy and has a low environmental impact. EPS products reduce energy consumption through insulation systems and fuel usage, due to being lightweight, reducing climate-damaging C02 emissions. EPS is inert and doesn’t produce any methane gas or contain chlorofluorocarbons (CFCs). This means it does not harm human or animal health, or the environment.

Is EPS going to be banned?

Only throw away coffee cups and hamburger clam shells. Everything else is here to stay.

Why should I use Expanded Polystyrene?

Comparative analysis shows that EPS, in many cases, outperforms all other insulation and packaging materials. EPS products are moisture-resistant, lightweight, can be re-used over again, are cost-effective and 100% recyclable. There are no comparable products. Polyfoam is Here to Stay.
