EPP Porous

Porous expanded polypropylene is a unique open cell bead that incorporates air pockets within a hollow cylinder shaped bead structure. The result being a foam that performs in many application areas and a foam that is simultaneously porous. Porous EPP has many beneficial characteristics:

  • Does not support microbial growth
  • Highly durable
  • Resists multiple impacts without damage
  • Good acoustics properties for noise reduction
  • Discharges no particles when abraded


APPLICATIONS

Automotive engineers benefit from Porous EPP in key applications to reduce noise, vibration and harshness (NVH), with tests showing noise reduction levels of up to ten times that of alternative materials. ARPRO® Porous is used extensively in car interiors to reduce noise levels without increasing weight.
