Reticulated Foam Sheet
Polyurethane foam sheets, including Reticulated Polyurethane, are part of Advanced Seals & Gaskets Ltd’s (ASG) extensive material range. Reticulated Polyurethane, also known as Retic Foam, Reticulated PU, open-cell PU, Filter Foam, or Skeletal Foam, features an open-cell structure and is available in PPI (pores per inch) ranging from 10ppi to 100ppi. Lower PPI foams (10–30 ppi) have larger holes and a distinctive net-like appearance, making them ideal for airflow and filtration purposes.
Why use Reticulated Polyurethane Foam Sheets?
Reticulated foam sheets are versatile materials used for filtration, vibration damping, sound absorption, and cushioning. Foam thickness and PPI grade determine airflow and filtration efficiency. Thicker sheets restrict fluid or air flow, increasing particle capture. Lower PPI grades allow freer flow, while higher PPI foams provide finer filtration and greater dust capture.
Reticulated foams are also compressible, lightweight, and durable, making them suitable for industrial, medical, and consumer applications. Their open-cell structure ensures excellent breathability and efficient performance in demanding environments.
Available grades of Reticulated Polyurethane Foam Sheets
ASG supplies reticulated polyurethane foam sheets in a variety of grades to meet specific application requirements:
- 10ppi–30ppi: Large pores for free airflow and liquid passage. Captures larger particles with minimal fine dust. Compressible with a scouring pad-like texture.
- 45ppi: Mid-range porosity allows controlled airflow while trapping smaller particles. Moderate compression resistance.
- 60ppi–80ppi: High porosity with very fine pores. Captures fine particles and slows airflow, effective even at lower thicknesses.
Benefits of using Reticulated Polyurethane Foam Sheets
- Lightweight and easy to handle
- Low odour
- Resistant to mould and mildew
- Chemically resistant
- Tear-resistant and compressible
- Washable and reusable
Advantages of using Reticulated Polyurethane Foam Sheets
Reticulated foams are ideal for a wide range of industrial and commercial applications due to their durability, chemical resistance, and customizable filtration properties. Key advantages include:
- Different PPI grades for tailored filtration needs
- Flame-retardant options meeting FMVSS302 standards
- Available in multiple colours, including marine-safe green and blue
- Resistant to acids, alkalis, fuels, oils, detergents, and lubricants
- Excellent for sound absorption and vibration management in aircraft, machinery, and household appliances
- Suitable for fluid management in cosmetic, medical, and industrial applications
What are Reticulated Polyurethane Foam Sheets?
Reticulated foam sheets are created by splitting large master blocks into various thicknesses, sometimes as thin as 5mm. The “reticulated” structure refers to the open, net-like cells. Lower PPI foams have larger pores for greater airflow, while higher PPI foams have more pores for finer filtration.
These sheets can be supplied as full sheets or converted into washers, pads, gaskets, or strips for various applications. ASG’s in-house processing allows for the creation of plain, self-adhesive-backed, or laminated sheets to meet bespoke requirements.
What are Reticulated Polyurethane Foam Sheets?
Reticulated foam sheets are manufactured by splitting master foam blocks into sheets, typically in sizes of 2x1m or 1x1m. The lower the PPI, the larger the pores, increasing airflow and particle capture. Higher PPI grades have smaller pores for finer filtration.
Sheets can be supplied in plain, self-adhesive-backed, or laminated forms for added thickness. Reticulated foams are versatile and can be cut or converted into washers, pads, strips, and gaskets, providing tailored solutions for a wide range of industries.
