Bio-Based Foam and Insulation

What is the difference between bio-based foam and common foam types? To save the environment, reusing materials became inevitable, but it is also very important that the new, eco-friendly product has the same performance and features.


How to Cut Foam? Tutorial.

Different types of foams are available to purchase. Closed-cell and open-cell foams, low-density and high-density foams.


Foam Density, Weight, Firmness and Usability

How to measure foam density? Foam density is measured in kilograms per cubic meter. This unit of measurement is important: foam density defines what is the use of the material.



Embossing is a process where the surface of a single foam sheet or a laminate material is given a 3D texture. For this the surface must be heated to a temperature where it becomes shapeable, than an engraved roll is pressed (with the negative version of the desired pattern) into the surface of the foam or laminate. After cooling the new structure becomes permanent, at least as long as not heated up again to a similar level.


The connection between foam color and density

There is a strong correlation between the intensity of a color of a foam, and the density of that foam. It is often experienced that the color is paler and lighter for a foam with low density (let’s say 30 kg/m3), compared to a higher density (for example 100 kg/m3). When a color is matched to the Pantone palette, the density range where the desired color will be indeed, always has to be kept in mind.


Foam Materials: Polyethylene, Polyurethane, Polystyrene

What is foam made of? Many different foam types are made from many different materials, based on the product’s density and the process. In this article, we will introduce the most common foam materials: polyethylene, polyurethane, and polystyrene.


Heat Lamination

Heat lamination is a process for producing multi-layer products (these are called laminates), which allows the properties of the layers to be combined. It can be understood as ‘welding’ the layers to each other.


Can the properties of polyethylene material be influenced?

Plastics were originally made of a few materials, but this has changed a lot over the years. Today, thousands of types of plastics are produced by adding various natural and synthetic materials.


How are physically cross-linked foams manufactured?

Physically cross-linked polyethylene foam, also named IXPE foam. It has excellent mechanical properties and advanced dimensional stability, which is why it is widely used in various fields.


What must be considered when storing polyethylene foam (PE foam)?

When storing PE foam, we need to follow several rules in order to maintain the highest quality of the material as possible.



During thermopressing the foam is heated on both the top and the bottom side, then pressed from both directions by a cooled two-part mold, and then released. It is possible to make foldable products with it, or to give very deep patterns to the surface.


Which are the features of the PE foam if compared to the EVA foam?

In this article, we compare XPE foam with EVA foam.
