XPE foam (Polyethylene) is chemically crosslinked polyethylene foam product. Crosslinking the PE foam makes it more resistant against certain substances like chemicals and also high ratio of heat resilience. Therefore, due to crosslinking feature, the surface of foam becomes considerably smooth and soft moreover making it much more flexible and lighter.
High Water Absorption Ratio, Harmful for health, Costly
Good Aging Resistance, High Elasticity and Smooth Surface, Lightweight, Chemical Corrosion and Heat Resilience, Highest Density
Constructional Usage in Ceilings, Sound Proofing Pads, Outdoor Mattresses and Ducts, Inside Sport Recreational Goods, Automobiles and Aerospace
XPE Foam or XPE Rubber is a cross-linked polyethylene product. In fact, polyethylene is a vinyl polymer from the monomer ethylene.
You can see polymer products in your daily life. It is also the popular plastic.
The XPE Foam product was synthesized the German chemist Hans von Pechmann in 1898. He is also finding the formula accidentally when he investigating the Diazomethane.
The first commercially use & development of PE Foam began with promoted polymerization at normal temperature.
Without pre-treatment, you can’t even imprint the adhesives on the surface of XPE Foam.
We have different density classes of Polyethylene. You can see the names on below:
High-density polyethylene (HDPE)
Cross-linked polyethylene (PEX or XLPE)
Medium-density Polyethylene (MDPE)
Linear low-density polyethylene (LLDPE)
Low-density polyethylene (LDPE)
Very low-density polyethylene (VLDPE)
In fact, the material properties depend on the structure.
In every industry, XPE Rubber or Polyethylene Can be found! For example, you can find polyethylene in grocery bags, shampoo bottles & even bulletproof vests.
In comparison with EVA Foam, the XPE Foam is more cost-effective. It is also firmer & more resistant to heat than EVA Foam.
You can produce the sheets of XPE Rubber in the molds.
After all, we can see the XPE Foam applications on below:
You can see that Polyethylene products can be used everywhere. The important thing to know that XPE Rubber must be produced at a high level of reliability.
For example, in automotive uses or health care reliability is one of the most important parameters for every customer.
Polyethylene is known as a very useful & practical product in the foam industry.
We can see some XPE Rubber benefits below:
It is also a high resistance to moisture.
Like every product, XPE Rubber may show some disadvantages.
For example, XPE Foam has high water absorption & it is harmful to health. For example, some abnormalities can appear in some organs of the body.
The flammability range of XPE Rubber is low. The burning behavior is like a candle flame.
About the electrical behavior or electrical property, you must know that one of the very important benefits of XPE Rubber plays an important role. This product is Anti-static foam. That means the polyethylene is a very good electrical insulator.
