Acoustic Foams

How does that sound?

We have been working diligently to create acoustic foam products that are lightweight with exceptional sound-proofing characteristics.

Today we produce a portfolio of acoustic foams, suitable for a wide range of applications.


  • Automotive
  • Packaging
  • Apparel
  • Sound dampening
  • Industrial
  • Medical
  • Marine

Our products meet a high standard for flammability performance for urethane.


UL94 HF-1 Polyester Foam

PyroPore™ S Series

The PyroPore™ S Series embodies protection and safety. It provides excellent resiliency, die clickability, and versatility in a fine-cell polyester foam. The foam is formulated to suit flame lamination, allowing for more complex composites to be manufactured {at the fabricator level}.

With PyroPore™ the possibilities are endless, from packaging to sound insulation.

Certified to UL94 Standards with an HF1 Rating.

UL94 HF-1 Polyeter Foam

PyroPore™ E Series

The PyroPore™ E Series offers the same quality, resiliency, and versatility as our PyroPore S Series but in a fine-cell polyether foam structure. The polyether properties meet UL94 HF-1 specifications and are better suited to environments where moisture and humidity may be present, temperatures are cooler, or where the application may cause dynamic heat build-up.

Examples include sound dampening, packaging, insulation, flame and hot roll lamination.

Certified to UL94 Standards with an H1 Rating.

Cell-Controlled Non-reticulated Polyester

CustomPore™ S Series

Body: CustomPore™ S is a standard cell-controlled non-reticulated polyester foam that can be specially formulated to meet a wide range of specifications – including flammability standards such as those laid out in the Federal Motor Vehicle Safety Standard No. 302 (FMVSS302).

This is truly technical foam at it’s best, by producing a specific cell structure that is required to meet the product application – such as paint rollers and ink carriers.

These foams appear in a wider range of applications including packaging, medical, apparel and sports, acoustical and industrial.

Certified to UL94 Standards with an H1 Rating.

Semi-rigid Polyurethane Foam

CFR Series

The CFR Series is a lightweight open cell semi-rigid polyurethane foam originally developed for the automotive industry as an under-the-hood layer providing superior sound and heat insulation.

The open-cell foam offers excellent sound absorption, energy absorption, temperature resistance, and hydrolysis durability with low thermal conductivity. These qualities have made the CFR Series an ideal choice for:

  • Automotive acoustical and heat insulation applications for internal combustion engine and battery electric vehicles
  • Refrigeration and heat management
  • Marine
  • Audio

Flammability has been tested and certified as meeting the Federal Motor Vehicle Safety Standard No. 302 (FMVSS302).

Available in the color gray. Provided as buns or sheets. Thermoformable.
