Polyurethane Foam

Closed cell foam products are well suited for use in the aerospace sector. Closed-cell polyethylene foam can be used in a variety of applications since it is both lightweight and resilient. All of Bracken

Polyurethane foam, or PU foam for short, is known for being highly flexible and also very resilient. Polyurethane is a core member of the diverse, wide-ranging group of polymers and plastics. It can come solid or with an open cellular structure, and you can get rigid or flexible polyurethane foam, depending on the function for which it is necessitated.

Foam’s plastazote foam is available in a variety of densities, hardnesses, and colours.

Clients in the aircraft industry benefit from closed cell foam materials with a high density, such as polyethylene and plastazote.

Common uses for flexible polyurethane foam

Space filling for computers and electronic products
Cushioning in upholstery and furniture
Impact absorption for electronic devices such as laptop computers
Sound deadening for dampening acoustics in studios and interior open spaces
Protection against electrostatic discharge (ESD) for electronic devices during manufacture and transportation
Patient care products for healthcare facilities, from comfort supports to drug administration
Presentation box inserts at retail points of sale

Anti-Static Polyurethane

How is PU foam made?

PU foam is made from the reaction of mixing polyols and diisocyanates, which are both derived from crude oil, in a stainless steel tank. Some additives may be needed as per the intended application of the PU foam.
The reacting materials are passed through a heat exchanger, which adjusts the temperature to the necessary reactive level, while being pumped into pipes. The polymerisation occurs within the pipes and the polyurethane is formed once the liquid reaches the end of the pipe.
The polyurethane is emitted from a dispensing pipe onto the production line, with a spool of rolling paper moving it along a conveyor. During the dispensing process, its mixture with carbon dioxide causes it to expand and it continually rises as it moves along the conveyor.
After this expansive reaction, a second top layer of paper is rolled on (along with possibly some side papers if necessary). Each layer of paper gives the PU foam its shape.
Once it reaches the end of the production line, the foam insulation is cut with an automatic saw to give it the required length.
