Expanded Polypropylene (EPP) / Expanded Polystyrene (EPS) processing


Plastics molding technology has been a Knauf Industries core business ever since its creation. Our expertise in EPP and EPS helped us to develop our unique offering for the automotive industry where these materials have gained a strong foothold. Our 35 EPP/EPS processing plants are strategically located to best serve the supply chains of our most demanding international customers.

Expanded Polypropylene (EPP) / Expanded Polystyrene (EPS) processing

The industrial expertise, molding know-how and market experience are crucial for solutions development of foam products on the automotive market. Our teams work closely with clients to evaluate their needs and define technical requirements for expanded foam products that meet their expectations. After thorough analysis and close communication with our customers, we work on custom-designed foam solutions or design to cost solutions, ensuring through our recommendations the suitable material choice and specifications for meeting quality and functional targets of the parts. Our Program Management System is bringing to OEMs and Tier-1 clients engineering support during all products’ life, i.e. from project advanced phase till end of supply of products, including hence design, development, and industrialization of parts with possible added-value operations.

Plastic injection for automotive


In our Polish plant in Wrocław we manufacture plastic parts by thermoplastic injection molding for the automotive industry. Robust injection molding technology stemming from our foundations in the home appliance industry has enabled us to start production of EXTERIOR and INTERIOR car parts for Tier-1 suppliers in 2012.

Plastic injection for automotive

The machine park installed in the Wrocław plant has 17 machines (from 40T to 2000T). All presses are equipped with SEPRO manipulators. On selected machines we have ABB six-axis robots, which can be used to perform difficult operations directly on the  machine such as: ingot cutting, gradation, and flame cutting (PP surface activation)

At present our service covers the full range of design works:

  • Full simulation of processes (FS, DFM, Mold Flows) based on CAD model
  • Development and coordination of tool implementation (Europe, Asia)
  • Coordination of texturing (Standex, Mold Tech)
  • Testing, measuring reports
  • Full reporting by PPAP or VDA
  • Production and service of molds

In addition to conventional injection, we perform additional operations directly at the machine. Their scope includes: assembly of soundproofing elements, clips, hooks, ultrasonic welding and others. Injection molded parts for automotive have become the flagship product of the Polish Knauf Industries factory.

Knauf ID lab
Welcome to our new initiative - the ID Lab. Together with our top product and technology development experts, we have created a new space dedicated to innovation and development of cutting-edge technologies. Our main goal is to help our clients preserve their leading position in the competitive automotive market.


With our processing equipment, we are able to process a variety of foam materials as well as all known co-polymers.

We manufacture our automotive packaging and components using a variety of expanded foam materials including expanded polypropylene (EPP) and expanded polystyrene (EPS) and other special co-polymers used for Lost Foam casting process. For the production of injection molded automotive components we efficiently process: PC, PS, ABS, PC/ABS,PP/EPDM, PA6 GF30, PP GF30,PP+T and many more.  

Expanded Polypropylene EPP

Expanded Polypropylene (EPP)

Expanded Polypropylene (EPP) is a trustworthy and well-tested material used in a wide variety of automotive applications and valued by the most renowned car-makers

Lightweight, energy absorbent and mouldable EPP enables component-consolidation and assembly-time reduction improvements and can adapt to space and shape constraints across vehicle systems. Expanded Polypropylene can be made in a wide range of densities, from 15 to 250 grams per litre by fusing individual beads together during a moulding process.

This highly versatile, closed-cell bead foam provides a unique range of additional properties rated highly by the automotive industry:

  • Light weight
  • Outstanding energy absorption
  • Multiple impact resistance
  • Thermal and acoustic insulation
  • Buoyancy
  • Water and chemical resistance
  • Exceptionally high strength to weight ratio
  • 100% recyclability

EPP is successfully used in the automotive industry in conjunction with other components and materials to make vehicles lighter and safer.

In Knauf Industries we are striving to create additional value for our cusomerts making the most of our foam materials. That's why we developed a palette of 36 textures in 4 lines corresponding to the latest trends in industrial design.

The textures with graphical shapes on the surface of EPP material make it an attractive alternative to traditional foam parts, which additionally require a decorative finish.

Our offering of Expanded Polypropylene components comprises:

  • Bumpers
  • Seating
  • Safety, interior and storage systems

Moreover, EPP proves to be the perfect material solution for rotation packaging protecting fragile car parts during transport and warehousing.

Expanded Polystyrene EPS

Expanded Polystyrene (EPS)

Expanded Polystyrene, is a cellular material widely used in the automotive industry. EPS is produced via the expansion of polystyrene beads by heating them with steam. Thus they are transformed into fine spherical shaped particles which are comprised of 98% air and 2% polystyrene. The material can be molded into packaging and components of versatile shapes and sizes.

Being an expert in light and resistant foam materials we elaborate for our automotive clients a variety of cost-effective packaging and cushioning solutions from Expanded Polystyrene.

The material boasts a great number of properties that make it a privileged alternative to other plastics:

  • Expanded Polystyrene is 98% air, 2% polystyrene
  • wide range of densities, from 8 to 150 grams per litre
  • exceptionally light and flexible, yet durable
  • EPS is safe and environmentally neutral
  • excellent insulating and acoustic properties
  • 100% recyclability
