Sponge Rubber Sheet Capabilities

Sponge rubber sheet is extremely versatile. It is available in a variety of materials with distinct features and capabilities that are designed to suit a broad range of applications. Here are some of the most common materials Aero Rubber Company uses to produce sponge rubber sheets:


Polyurethane Sponge

This material is divided into two distinct foam types: polyester and polyether. Also known as PU, the sponge is known for its exceptional durability and practicality in the oil, gas, construction and transportation industries.

Silicone Sponge

Silicone sponge is ideal for applications where top-quality performance is needed. This includes industrial applications that expose the sheet or fabricated parts to high and low temperatures and compression.

PVC/Nitrile Rubber Sponge

Rubber sponge is a blended polymer of nitrile and PVC materials. It is highly effective for sound reduction and is heat- and impact-resistant. The material is often used to create seals and roof insulation.

Neoprene Sponge

This material comes in two variations: neoprene sponge blend (Neoprene, EPDM, and SBR), and 100% neoprene sponge (no blend). The blend offers additional weather- and wear resistance, whereas 100% neoprene provides excellent oil resistance.

FKM/Viton Sponge

Fluoroelastomeric (FKM) Viton sponge rubber is extremely durable and can be exposed to oil, acid, UV rays, heat, and precipitation without degrading. This makes it ideal for applications like high-temperature oil and fuel gaskets, acoustic dampening equipment, and other heavy-duty chemical-resistant industrial uses.

  • Flame-retardant silicone sponge

In addition, we offer the following production capabilities:

  • Commercial- and specification-grade compounds customized to your needs.
  • Material as thin as 0.005 inches or as thick as 6 inches with multiple rubber sheets laminated together. Sheets can be as wide as 54 inches.
  • Die-cutting and stripping cutting of sponge rubber sheets.

Open- vs. Closed-Cell Sponge

It is important to understand which type of cell sponge will work best for your intended use. The main distinctions between open- and closed-cell sponge are their permeability and density or compression. Both types of sponge are durable and long-lasting, even with heavy use.

Closed-Cell Sponge

Closed-cell sponge is harder and less permeable. Since closed-cell sponge does not absorb water, it’s frequently used in products that require strength and security, including gaskets, stripping, or wiper blades. It can be formulated to offer resistance to high and low temperatures, oil, chemicals, abrasion, and fluids.

Open-Cell Sponge

Open-cell sponge is softer and more permeable.  It is ideal for manufacturing mouse pads or orthotics. It is also excellent for sound dampening and shock absorption applications.
