During winter, you will be working your heater double time if you don’t have the proper silicone sponge insulation to block cold outdoor air from entering. Also, consider hurricane season, many houses suffer from weather damage and water seeping into the house from cracks, crevices and windows. Not all construction companies make use of the best materials to seal these important locations off. When you find that you windows still allow your warm heater air to leak out and cold air to enter, chances are you do not have the proper weather stripping. Old windows from houses built in the 90’s and older may require new window stripping of silicone too.
What is Silicone and the Differences between a Sponge and Foam
Large pieces of machinery like gaskets and boiler casings require materials that will seal holes and provide it cushioning and support. One of the materials used by many is silicone, which has two forms: the silicone sponge and silicone foam.
Since silicone is a very versatile material, it comes in many shapes and sizes. While silicone foams are usually in the form of a tape, there also exists a silicone sponge sheet. The applications mostly vary on the ingredients used in making them.
Here are certain benefits of silicone and the differences between a silicone sponge and silicone foam.
Benefits of silicone
In the commercial and machinery industry, silicone is a widely applied element, ranging from electronics, transportation, and construction. Certain qualities make silicone a go-to material for various industries.
Withstands extreme temperature
Silicone is one of the most durable materials that can withstand extreme heat and cold. Its temperature tolerance ranges from -73°C to 260°C. The coldest is equivalent to the weather in the Antarctic, while the hottest is five times the heat in California.
Seals water
The silicone’s sealing feature is perhaps the most sought-after benefit of the material. Because it is extremely water repellent, it is used in constructing buildings and repairing heavy containers and pieces of machinery.
Silicone Sponge vs. Silicone Foam
Made out of similar materials, many get confused between silicone sponge and silicone foam. To help you find the appropriate equipment, here are certain factors that distinguish the two.
Creation
A silicone sponge sheet contains a mixed silicone gum rubber base, which gets cured in an oven. In contrast, a silicone foam consists of a liquid silicone cured in an oven.
Density
A distinguishing property is the density of the materials. Sponges have a higher density, tear, and temperature resistance. Foams are generally less dense than sponges because they are liquid-based.
Uses
Due to its high density, silicone sponge is a perfect option for windows, enclosures, machinery, and equipment that gets exposed to rain and other harsh outdoor elements. On the other hand, silicone foams are a great alternative in cushioning as well as sealing dust and light water.
In short, the main difference between the two is their power to hold extreme conditions. Generally, silicone sponges are used for heavy-duty projects and outdoor use, while silicone foams are for maintenance and repair of light materials and equipment.
Open-cell vs. closed-cell Silicone sponge
Silicone sponges have two different types: open cell and closed cell. In the previous discussion, what is being referred to as silicone sponge used in heavy industries is the closed cell silicone sponge.
Open-cell sponges are not used in heavy-duty projects since they are not as water resistance as a closed-cell. A perfect example is household materials such as a kitchen sponge, which retains only minimal water.
Conversely, a closed-cell sponge is a water-resistant type used in gaskets and heavy equipment. In regular use, you can find the best in scuba diving suits, which are incredibly water-resistant.
Various other materials have indeed developed to give stronger support and cushioning for heavy equipment. However, silicone is still the most reliable and proven material.
