The chemistry of Polyurethane foam dictates the cell structure and ultimately the properties. The basic reaction is that of a polyol and isocyanate. The polyol can be of 2 derivatives, a polyester or a polyether, which determines the types of PU foams.
These tend to be the softest of grades and used in many retail and low cost applications. Typical examples are:
Mainly of improved physical properties, and controlled cell structure. Used where better performance is required. Typical examples are:
A special type of polyurethane foam, which by a special process called Reticulation, the cell windows within the foam are removed to create a completely open cell network and a product capable of use in specific filtration applications.
These are special grades of foam which are flexible, high density, products that offer design engineers many outstanding features. They maintain excellent resistance to compression set (collapse), exhibit high resiliency, good vibration damping and impact absorption. They can be made to tight tolerances and continue to perform after repeated deflection.. Uses include gaskets and seals for small electronic devices, shoe insoles.
These are specially treated Reticulated foams; which are compressed under heat until the foam takes a set. The resultant foam exhibits a capilliary action when fluids such as ink come into contact, and they absorb the fluid to become a reservoir for inkpads, ink rollers, inkjet cartridges etc.
Our Visco Elastic foams offer a unique combination of conflicting properties that are ideal for comfort management and protective padding applications. These urethane foams soften and conform when exposed to warmth, giving gentle, virtually pressure-free support.
When the foams take a direct blow, however, their high energy-absorption characteristics enable them to absorb up to 97 percent of an impact and have an open cell/ airflow capacity. While they are slow to recover after deflection, they effectively resist compression set. Uses include wheelchair cushions, mattresses, pressure relief pads, bicycle seats and wrist-rests.
