The chemical modification of the foam surface on the basis of environmentally friendly and safe substances ensures a significant increase in surface tension, which results in excellent long-term stability. Therefore, the AST treatment offers decisive advantages over conventional corona procedures.
Environmental sustainability is very important to Trocellen, which is why it created TR-EECell, the Bio-based cross-linked polyethylene (PE) foam. The greatest thing that this kind of PE has the same properties as the conventional version, but it is much more environmentally friendly.
Polyethylene is basically translucent or milky-white in color, but almost any desired color can be achieved by using plastic colorants. Plastic coloring is useful in creating the image of a product, also can help improving usability and quality. Additionally, it plays a big role in decoration and identification.
A chemical cross-linked foam forms a resistant surface. Cross-linked closed cell polyethylene foam means that during cross-linking, the molecules connect by chemical bonds, forming a structure branched from the straight carbon chain, thus creating a more durable structure. The fineness of the cellular structure gives the material even greater stability.
The foam manufactured by Trocellen is the physically cross-linked polyethylene foam. This PE foam can be produced with modern technology, has excellent mechanical properties and advanced dimensional stability.
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.
In this article, we point out the differences between the low and high-density foam. These products are both made of LDPE (Low Density PolyEthylene) but they differ in their density [kg/m3] and thus, the use of these materials is not the same.
Plastics were originally made of a few materials, but this has changed a lot over the years.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.
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.
Its chemical formula is (C2H4)n, i.e. this is a carbon- and hydrogen-based material. Polyethylene foam is a closed cell solid material and is foamed with gas. Each gas phase is separated by a layer, which yield the cells. Closed cell cross-linked polyethylene foam is the sum of these cells.
In this article, we compare XPE foam with EVA foam.
