Insulation and thermal stability
EPP provides effective thermal insulation, maintaining temperature for optimal performance.
WHAT IS EPP?
Expanded polypropylene is a plastic material characterized by a honeycomb structure that gives it excellent shock and vibration absorption properties. It is made from polypropylene granules that are expanded at very high pressure by a blowing agent, to form expanded polypropylene.
At the end of the process, it is free of any residual blowing agent. These expanded polypropylene beads are then die-cast to obtain the desired shape, whether for protective equipment, packaging parts or industrial components.
THE UNIQUE CHARACTERISTICS OF EPP
Expanded polypropylene stands out for its many properties that make it a versatile and high-performance material.
The lightness and strength of this material make it ideal for absorbing impacts and vibrations, while maintaining high mechanical resistance. Its excellent thermal and acoustic insulation makes it valuable in multiple applications and many industries. In addition, EPP is resistant to moisture and chemicals, increasing its durability and reliability. Finally, it is recyclable, making it an environmentally friendly option, meeting sustainability challenges.
A MATERIAL COMPLIANT WITH ENVIRONMENTAL ISSUES
Expanded polypropylene (EPP) is a material that is in harmony with current environmental issues. In addition to its lightness and robustness, it is distinguished by its recyclability, allowing products to be reused at the end of their life and reducing the ecological footprint. Its production requires less energy compared to other materials, and it emits few greenhouse gases. In addition, its extended durability minimizes the need for frequent replacement, thus contributing to more responsible consumption of resources.

HVAC: optimal thermal and acoustic performance
The EPP, fire-resistant and insulating, is ideal for boilers, radiators, water heaters and air conditioning.
Automotive: weight reduction, protection and shock absorption
EPP is resistant and absorbs shocks, it helps to lighten vehicles, improve safety and energy efficiency.
SPORTS AND LEISURE
In the leisure and toy sectors, products made of Neopolen® or EPP benefit from the combination of light weight and durability.
In addition to these properties, this special foam lends itself quite well to the realm of sports, thanks to its high resilience and elasticity.
REUSABLE PACKAGING AND TRANSPORT CONTAINERS
Compared to other foam materials, Neopolen® or EPP is especially suitable for reusable packaging and reusable transport containers. The high resilience after static and dynamic stressing and the good chemical resistance, as well as the excellent cushioning performance at extremely low weight, make Neopolen® or EPP ideal for these applications.
Examples are in-plant transport containers for automobile mirrors, brake calipers or steering gears. Depending on the level of stress, 100 and more transport cycles are regularly achieved. In this way Neopolen® or EPP helps to economize on packaging materials and lowers costs.
FOR HEATING EQUIPMENT AND ELECTRONIC DEVICES: MANY FUNCTIONS IN ONE
As an engineering material with many different properties, Neopolen® or EPP performs several functions at once. The molded parts are equally suitable for packaging, for casings, as impact protection and as heat and sound insulation, e. g. for electronic devices and heating equipment.
Therefore, new design possibilities are opened up in the field of technical and electronic devices. Components such as ventilator fans or electronic components that were previously fastened in metal holding devices can be reliably anchored by closefitting insertion into the viscoelastic assembly frame of Neopolen® or EPP. This saves time and weight while simultaneously assuring a high level of transportation safety.
COMPONENTS MADE OF EPP or NEOPOLEN® SUPPORT THE MEGATRENDS OF THE AUTOMOTIVE INDUSTRY
Due to its mechanical properties, Neopolen® or EPP is particularly suitable for components subject to impact stress. The low weight, high energy absorption and good deformation performance of Neopolen® or EPP, even after repeated impact load, are outstanding qualities for components in automotive construction.
Neopolen® also has negligible water absorption, can be relied upon to function reliably over a wide range of temperature, and is thus predestined for internal and external applications in automotive construction.
