Polyurethane foam is created in a basic chemical reaction of a Polyol and Isocyanate, and the final product is determined by the addition of other chemicals but also by the actual polyol type determines the 2 basic family

types.

Polyether Foam - These tend to be the softest of grades and used in many retail and low cost applications. Densities range from 15 – 30 Kg/m³ as standard but others are available. The foams are prone to “blow holes” due to the foaming process.

Polyester Foam - Mainly of improved physical properties, and controlled cell structure. Densities in general

are from 20 – 60Kg/m³ Used where better performance is required and more technical characteristics.

PU foam is also known as Sponge, because early grades were developed that gave the look of Natural Sea Sponges, and are used for car sponges or bath sponges. Intec Foams has the ability to create shapes from

these grades for bespoke applications.

There are also some grades of sponge and foam that have been developed with Hydrophilic properties, used

for absorbing water e.g. in the Pottery Industry for removing water from pots before firing.

Technical Grades exist, which are derivatives of the above 2 family types:

Reticulated PU Foams

Special foams where the cell windows have been completely removed by a controlled explosion technique called “Zapped” Reticulation; in polyether and polyester grades. Available in different porosities to filter out different particle sizes.

Typical Applications:

• Water Filters
• Pond Pump Filters
• Tertiary Sewage Tank Filters
• Heat & Moisture Exchange Filters
• Cosmetic Foams
• Air Filters
• Ink Reservoirs
• Pre-Cursor’s for Ceramic or Metal Filters
• Many More
• Fire-blockers for seating applications in aircraft

Microcellular PU Foams

Flexible, high density foams with excellent resistance to compression set (collapse), high resiliency, good vibration damping and impact absorption. Similar to Poron™ grades.

Typical Uses:

• Gaskets and Seals.
• Shoe Insoles & Orthotic Devices
• Sound absorbers for small communications devices
• Prosthetic Padding
• Shock Absorbers
