Filter Foam Supplier

Reticulated polyurethane foam is a very porous, open-cell, low-density polyurethane foam. This foam type undergoes a thermal reticulation process that removes the window cell membranes. This post process strengthens and reinforces the foam walls and minimizes the possibility of open channels. The end result is a net-like structured foam that provides exceptional filtration properties and highly suitable for sealing applications because it prohibits air flow.

Because of its many desirable physical properties, reticulated polyurethane foam is very popular material in a wide array of industries and applications, including filtration, fluid management, sound absorption, cleaning, packaging, and sealing. Properties such as lightweight, high porosity, durability, and strength, low odor, and high resistance to chemicals and mildew make reticulated foam very desirable in such industries as medical, automobile, cosmetic, and air conditioning to name a few.

Used as a puppet foam (also known as Scott foam), reticulated foam is an optimal material for carving or patterning flexible heads, hands, arms, and more. This foam material is very light, durable, and flexible. Its porous nature gives this foam material a rougher texture, which also makes it more forgiving and easier to cut and carve.

As a top reticulated polyurethane foam supplier and filter foam manufacturer in southern California, Atlas Foam offers reticulated polyester foam in a range of pores per inch (PPI). We can also cut reticulated foam to the desired thickness.

High-Quality Reticulated Foam Products

At Atlas Foam, we offer reticulated foams with a variety of pores per inch (PPI). We have designed and fabricated numerous solutions using reticulated foam. We are capable of designing, fabricating, and manufacturing reticulated foam products to your custom specifications.

Foam Sizes and Dimensions

We supply reticulated polyurethane foam in sizes ranging from the following:

  • Up to 16” thickness
  • Up to 72” width
  • Up to 144” length

We can accommodate larger and custom sizes by bonding additional or multiple pieces together.

Foam Firmness

We offer reticulated foam in a variety of PPI sizes, ranging from 10 PPI to 90 PPI.

Specialty Foams

Atlas Foam Products carries a specialty Dri-Fast foam material that is highly suitable for outdoor use where the presence of water and moisture is frequent. This specialty reticulated polyurethane foam is anti-microbial and prevents moisture buildup, making it highly desirable material for patio and outdoor furniture. Its open-cell structure and porous nature allows a substantial amount of airflow and water to drain through. This also helps prevent water retention and inhibits the growth of mildew and mold.

Foam Density

PPI is an important characteristic that helps distinguish the different types of reticulated foam. The PPI value helps determine the types of application and how the foam is used. As the PPI value increases, the pores sizes or openings decrease in size. For example, reticulated foam with a lower PPI value is generally designed to enhance and promote greater air flow, because of the larger pore sizes. In contrast, reticulated foams with high PPI value are ideal for sound absorption and liquid filters.

Foam Colors

We offer PPI reticulated filtration foam in charcoal and natural/white.
