![]() The architecture is determined by the cell wall thickness, the size distribution and the shape of the cells. Indeed, the mechanical response of these materials depends on their architecture, and on the intrinsic properties of the polymer in the cell wall. Whatever their use, their optimisation needs the understanding of their microstructure-mechanical properties relationship. Combining good mechanical properties with a low density, rigid polymer foams can also be used as structural materials. For these reasons, they are widely used in aircraft industry, automobile, buildings, packaging …. Made of a skeleton of more or less regular open or closed cells, they have a high energy absorption capacity, particularly useful for shock applications, acoustic and thermal insulating properties, in some cases, filtering applications, etc. All orders made before 11:00 am are dispatched to you for the next working day delivery.Polymer foams are more and more used in industry. This helps to add loft to your foam cushions and makes it easier to insert them into covers.įinally, you just need to place your order. You can choose to add both dacron and stockinette to your order. We have a variety of different foam types to choose from, many with a high density.Īdd-ons are the next step.

We’ve been providing our quality products for over 40 years and now offer customers the ability to purchase custom cut foam online. Foam converting is our business and we know how to do it correctly. GB Foam is the UK’s longest online retailer of high-quality foam. The general rule is – the higher the density, the greater the longevity! High density foam is known to be long-lasting and is unlikely to break down at the same rate low or medium density foam could. So for example, if a certain foam grade is stated to weigh 2.5lb’s, that is how much a 12 x 12 x 12 block of it weighs. The way the density of foam is measured is by weighing a 12 x 12 x 12 block of the material. It essentially is used to indicate the mass of a material per a measurable size or volume. ![]() Being so structurally compact is the main reason this foam type has such an impressive lifespan.ĭensity in foam applies in the same way as any other use of the word. Unlike some cushion fillings, sofa cushions containing this foam do not tend to sag as frequently. This does so whilst still providing excellent levels of support and is able to quickly spring back into its original form. When used in a sofa, for example, we can note how its unique structure works to conform to the contours of a user’s shape. As a result of this, it is known to be incredibly durable which helps to ensure longevity. High density foam has a compact cell structure and as such is very dense, hence the name. It’s the best way to ensure both reliability and long-lasting comfort in your seating. Looking to upgrade your mattress, bay window seats, sofa, chair cushions, caravan cushions, camping bed or camper van? Using high density foam is an excellent way to do so. High Density Foam can be used for a variety of different projects.
