Materials: ​

Expanded polypropylene, EPP.​

EPP is a polypropylene foam material comprising expanded foam particles and is 95% air and just 5% polypropylene. Good for the environment: The production of EPP does not require any volatile, organic compounds, any CFCs or other chemical compounds that are known to be particularly harmful to the environment. EPP is 100% recyclable as a material and is therefore perfect for the circular economy.

EPP is used for three-dimensional applications combining energy absorption, high strength and very low weight with chemical resistance, thermal insulation and acoustic insulation.

EPP has extremely versatile uses and its range of applications at Flatz extends over countless areas:

  • Multi-purpose packaging and transport containers (e.g. packaging incl. ESD protection and transport for electrical devices, carrying cases for bicycles, thermo boxes/cool boxes, …)
  • Load carriers as reusable packaging
  • Automotive sector (e.g. seat stiffener, sun visors, seat, armrests, …)
  • Heating, air conditioning & ventilation (e.g. cladding for heaters, ventilation housings, pipe cladding, …)
  • Sport & leisure (e.g. balls, foam rollers, drinks coolers, model aircraft, giant building blocks …)
  • Furniture and outdoor items (seat cushions, flowerpots, stools, …)
  • Medicine & food containers (transport of medicines, fish, ice, …)
  • Safety (e.g. knee protection, head protection, …)
  • Boat and ship building (e.g. wheel, helm core, …)
  • Sound insulation (shell of vacuum cleaners, pumps, control devices, …)
  • High-quality surface structures for visible parts

EPP: The properties.​

  • Fracture strength
  • Low weight
  • Isotropic deformation behavior, regardless of the impact direction
  • Easy to produce moulded parts with almost any geometry
  • Environmentally friendly – 100% recyclable
  • Largely unchanged energy absorption even after multiple impacts
  • Electrostatic discharge protection provides a greater level of protection from electrostatic discharge with constant surface resistance of less than 107 Ω (on request)
  • Self-extinguishing according to standard UL94 HF-1 (on request)
  • Moulded part density can be adjusted to suit specific requirements
  • Low water absorption (1 day = approx. 1%, 7 days = approx. 2.5%)
  • Functional reliability over a wide temperature range (over 100°C)
  • Good thermal insulation capacity
  • Good chemical resistance to most chemicals
  • Easy cleaning options and sterilizability
  • Great freedom of design in terms of color and surface finish
  • Sound-absorbing
  • Porosity absorbs sound in the frequency range between 400 and 10,000 Hz

Hängt von den Anforderungen ab: Isolierend mit Transportschutz, Mehrweg mit einfachem Handling, hoher Transportschutz und doch leicht und natürlich auch die Optik. Geht alles, fragen Sie uns einfach.
