Filled EVA

HPI specializes in filled EVAs for sound barriers

Our Filled EVAs

We are able to compound and extrude filled EVA thermoplastics. This means we are able to provide both resin and sheet products for sound barrier materials.

Our multiple custom EVA compounds have characteristics which include:

  • Low fog/ low VOC
  • High density sound abatement at thin gauges
  • Can be formulated for snap-fit applications
  • Fire retardant
  • Suitable for deep thermoforming draws
  • Ideal for die-cutting applications

We are also able to formulate, compound, and extrude new filled EVA blends based on your requirements.

Automotive OEM Standards


Our filled EVA passes common OEM specifications, such as Ford WSS-M99P32, GM GMW14171, and MSDC259.
