FAQ about EPS
We regularly get questions about our EPS and Piocelan products. That's why we have bundled the most frequently asked questions.
What is EPS?
EPS is short for Expanded Polystyrene. It's a light material that is usually white. EPS is also known as Styrofoam or airpop®. EPS is created by heating granules of polystyrene with steam. The granules then suck themselves full with air, which causes them to expand. They can become 60 times bigger.
These granules are also called pearls. After they expanded, they are blown into a mould. Then steam is blown through the mould, causing the pearls to expand once more. This eventually gives the product its desired shape. That's why EPS is also called ‘airpop®’, it consist of 98% air.
What is EPS suitable for?
EPS is originally an insulation material. But nowadays, it has a lot more purposes. That's because it has some interesting properties. It's light, insulating, shock absorbing, strong, pressure resistant and dimensionally stable.
Which materials does Hordijk EPS Delft use?
We use Piocelan. It's a material that is similar to both EPS and EPP. It also has different properties than EPS. This makes it really suitable for multiple use.
How environmentally friendly is EPS?
EPS is very sustainable. It consists of 98% air, and only 2% plastic. Not much raw material is needed to create packaging or an insulation plate. The energy needed to make an insulation plate is amply compensated by the reduction of energy use in the newly built house. At Hordijk EPS, it means that the production process is carbon-neutral.
As a responsible family business, we realise that we must handle the raw material diligently. That's why we spend a lot of time and energy to use materials responsibly. Both in designing the products and in the production process.
A responsible approach to the environment and the surroundings has been in our DNA for decades. That's why Hordijk EPS has the ISO 14001 certificate.
Can you recycle EPS?
Yes, EPS is 100% recyclable. This is something that a lot of people don't know. In more than 200 Dutch recycling centres, EPS is collected separately. So don't dispose of it, but bring it to the recycling centre for its second life.
For the corporate EPS users, there are various recycle systems. For example, Hordijk EPS has set up a special collection system for horticultural trays. Check out www.epsgardentrays.nl.
What does Hordijk need to make an EPS product?
We work with moulds. The mould is shaped like the product we are making. So for every product, there is a separate mould. A mould is made from aluminium and it's milled in the proper shape by the mould maker. It's difficult to determine what the exact costs of a mould are. It depends on various changing factors.
When is it interesting to make a mould?
At about 1,000 products per year, it's financially attractive for us to make a mould. We are happy to discuss the options with you.
