Aerogel is a broad term used to talk about an extraordinary group of materials that have been used since the 1960s in space travel, but are now finding uses across a whole range of industries. ‘Aerogel’ is not a specific mineral or material with a set chemical formula-rather, the term is used to encompass all materials with a specific geometrical structure. This structure is an extremely porous, solid foam, with high connectivity between branched structures of a few nanometres across.

Silica Aerogel Insulation Blanket are the least dense solid in the world today. Pyrogel Aerogel insulation blanket have low thermal conductivity, high temperature resistance, flame retardancy, low density, and also have certain waterproof effect.

Silica aerogel insulation blanket is the best thermal insulation blanket material so far, its pore size is lower than the atmospheric pressure under normal pressure, so the air molecules in aerogel gap are in a static state, thus avoiding the convection heat transfer of the air. The very low volume density of the Silica Aerogel Insulation and the bending path of the nanoscale structure also prevent the gas and solid heat conduction, and the “infinitely many” void walls can minimize the thermal radiation. Together, these three functions almost blocked all the ways of heat transfer, which is the adiabatic effect of aerogels to other materials.

1st advantage is Excellent heat insulation effect

The heat insulation effect of Silica Aerogel Insulation Felt is 2-5 times that of traditional insulation material, and the theoretical lifetime measured by Arrhenius experiment is 20 years. It’s almost the same life as the building.

2, reduce the thickness of insulation layer

The aerogel felt has the same thermal insulation effect and the thickness is only a fraction of the traditional material. After heat preservation, the heat loss is small and the utilization rate of space is high. And at high temperatures, the above performance advantages are more obvious.

3, hydrophobicity and fire resistance

Aerogel blanket water repellent, which can effectively prevent moisture from entering pipes and equipment. At the same time, it has the fireproof performance of the building A1, and the three-dimensional network structure of the aerogel avoids the heat insulation effect of other thermal insulation materials in the long-term high temperature use, such as sinter deformation, settlement and so on.

4. Convenient construction

 glass fibers exceeds the properties that each of them has individually. This fiber-reinforced composite is typically flattened into sheets or randomly arranged and woven into fabrics for use in all sorts of applications. Fiberglass fabric is lightweight, strong, and less brittle than other composite materials. One of the most prized properties of fiberglass is its ability to be molded into various complicated shapes.There is no major difference between the production of hot NBR & cold NBR. In fact, the cold NBR or hot NBR Foam is distinguishable with the number of branches.

In the procedure of monomer recovery, the unwanted solids were removed by latex which is sent through numbers of filters where it stabilized with “antioxidant”.

You can understand the difference between NBR rubber & any other kind of foam-like EVA Foam immediately.

In fact, when you get a piece of NBR foam from suppliers, you will find out the difference between the NBR foam & any other kind of foams like EVA foam , etc.Now that you have a basic understanding of fiberglass and mineral wool, let’s take a look at the differences between these two popular types of insulation.

Fiberglass vs. Mineral Wool: How They Stack Up

Glass wool is a kind of fibrous material made from the melted glass raw materials or cullet. It consists of two types: loose wool and superfine wool. The fiber of the loose wool is 50 ~ 150 mm in length and 12 × 10- 3 mm in diameter. By contrast, the fiber of the superfine wool is much thinner in diameter, normally under 4 × 10- 3 mm. And it is also called superfine glass wool.

The loose wool can be used to make glass wool blanket and glass wool board. The superfine glass wool can be used to make common superfine glass blanket, glass wool board, alkali free superfine glass blanket, hyperoxic silica superfine glass blanket, and it is also used to preserve heat in the exterior-protected construction and the pipelines.
