Foam products take many forms, but all are made by trapping gaseous bubbles in a liquid matrix. When it is cured, the end result is an extremely complex system of polydisperse bubbles separated by draining films. Depending upon the chemicals and manufacturing process used, the product may be water repellent or highly absorbent, and will also vary in hardness.

Sponge rubber may be either closed or open-cell in structure. The open-cell type consists of interconnected cells which allow the absorption and circulation of liquids and gases. This absorbency means the product should not be used where resistance to penetration by fluids is a necessity, unless it is protected with a surface coating. The reason we say this is because it isn’t always immediately obvious how absorbent open-cell sponge foams are; rather than being porous, the outer surface is continuous. However, this gives them good physical durability.

Owing to the fact air can pass freely between the cells, open-cell sponge foams are not memory foams. Instead, they display a high degree of compressibility, followed by rapid recovery from compression. This means they can be “wrung out” quickly – ideal for use as cleaning sponges.

Sponge rubber is generally made from polyurethane, although natural latex is also used (natural foam rubber makes a very durable and absorbent mattress material.) As with all foam materials, it is manufactured with a foaming agent, creating an air-filled matrix.

One method of producing natural sponge rubber is via the Talalay process, a complex method of producing natural latex shaped foams which was first used in the 1940s. Some of the products we at Technical Foam Services sell are still made by this process.

What is it that makes Technical Foam Services head and shoulders above other foam suppliers? Well, unlike many other foam manufacturers, at Technical Foam Services we don’t just sell foam, but we make it too! And it is this engineered approach to foam that means that we are able to offer the consumer foam that meets their particular requirements.

For example, we are committed to offering memory foam rubber in a variety of incarnations, which means that whatever density of foam rubber that you require, whether closed cell or open cell foams – with Technical Foam Services you’re bound to find what you’re looking for.

For example,  we offer silicone foam rubber which is particularly resistant amongst rubber foams, with thermal stability, flame retardancy and UV resistance, which makes it ideal across a variety of technical applications, such as HVAC applications and thermal insulation applications.

We also offer highly cost effective rubber foam solutions, such as PVC Nitrile which is both water tight and air tight, making it perfect for certain applications were lesser materials just wouldn’t do. These applications include weather sealing and even body armour.

When it comes to rubber foams, this is just the tip of the iceberg, and whatever industrial application you can think of there is bound to be a foam that is perfectly suited for the job – or if not there is bound to be a foam that can be adapted by us to suit your particular requirement. So, why not give Technical Foam Services a call. We’re bound to have what your looking for!

While most people think of neoprene as a material that’s almost a fabric rather than a foam, it really does fall neatly into the foam category. Technically speaking, it’s the brand name for a particular kind of foam rubber. While many people may immediately think of wetsuits when they hear the word, neoprene and similar materials are widely used in insulation of all kinds (including wetsuits), and as a high-quality packing sheet. For instance, it’s rubber foams of this kind that line most rigid camera and laptop cases.

The reason neoprene is one of the most interesting types of foam is that it has been around a long time. In fact, it was the first commercially viable alternative to plant rubber. As such, the advent of neoprene had a very significant impact on the world economy and on manufacturing. Before the advent of mass manufacturable, multi-purpose rubbers, the plant variety was in massive demand in the tropics of South America, India and Asia. The plant rubber boom fuelled new tropical economies and established transport routes into the interior of South America, but the raw substance was difficult to collect and conditions of workers in the rubber collecting districts were notoriously bad in many countries. Neoprene meant the end of all that, good and bad.

Neoprene and other foam rubbers are still going strong. For such an old technology, they hold their own with more modern substances in terms of insulating ability, resistance to extreme heat and cold, and tolerance to oils and chemicals. Neoprene remains – and has always been – an important material.

Rubber products come in a variety of forms, and there are options to suit people across the manufacturing industry. A lot of products these days use rubber as a main component, but you could well be wondering where you can find the right stockist. So, to help you on your way, here are a few tips.

First up, you’ll probably want to ask around for recommendations. Ask colleagues or business partners for any advice, as it can often be difficult to know where to start without a push in the right direction. This also ensures that you’re getting a good rubber supplier, because if they were happy it’s highly likely that you will be too.

But, if this isn’t possible, the Internet would be your next port of call. By searching online for appropriate rubber suppliers you’ll be able to find a huge number of options, and as long as you do your research there’s no reason why this can’t be incredibly successful. It’s a lot easier than hunting through the phonebook, and as long as they’ve got good reviews and you make sure to compare a few options you can be confident that you’ve made the right choice.

Or, if you want to save all that hassle, why not come straight to us here at Technical Foam Services? We have a great range of rubber and rubber products in stock at all times, and we’re confident that we’ll be able to give you just what you’re looking for. So, don’t waste time and energy, and instead come to the best straight away and see what we can do for you in the way of rubber foams.
