Thermal insulation is fundamental in various industrial applications, as it offers benefits such as efficient heat management, improved energy consumption, and increased safety on production lines.
Proper insulation helps maintain optimal operating conditions and reduces energy consumption by controlling heat transfer. However, given the wide variety of insulating products on offer, having some guidance in this area comes in handy when making an informed purchase decision.
In this article, learn more about the different types of high temperature insulation products offered by NUTEC, their applications, and use recommendations.
Classifying the different types of insulation products
As you can see in this previous article, high temperature insulating products are used in applications that can exceed 2910°F (1600°C). Depending on your application, they come in various product formulations and chemistries/temperatures. Three main categories are freely available on the market:
- Refractory Ceramic Fiber. This fiber is a blend of alumina and silica, capable of withstanding temperatures up to 2300°F (1260°C). Adding zirconia to this fiber allows temperatures up to 2600°F (1425°C).
- Low Biopersistent Fiber. Also known as biosoluble fibers, LBP consists of a chemical composition of calcium, silica, and magnesium. It is suitable for temperatures up to 2190°F (1200°C).
- Polycrystalline Fiber. With a chemical composition of polycrystalline mullite, this fiber offers high tensile strength, durability, and minimal shrinkage at elevated temperatures. It can be used for temperatures up to 3000°F (1650°C).
Insulation materials possess common features such as low thermal conductivity, low heat storage, high tensile strength, thermal shock resistance, sound absorption, and being asbestos-free.
Below is a list of the most common forms of industrial thermal insulating materials you’ll find in the NUTEC portfolio for industrial use:
- Bulk & Engineered Fiber
- Coatings and Mixes
- Vacuum-Formed Shapes
Insulation blankets are a versatile and widely used solution in the industrial sector. They comprise fibrous mechanically needled products to create an efficient thermal barrier.
By trapping air pockets between the fibers, insulation blankets effectively reduce heat transfer. They are commonly used in HVAC (Heating, Ventilation, and Air Conditioning) walls, ceilings, pipes, and ductwork due to their flexibility, ease of installation, and ability to provide comprehensive coverage, thus promoting energy efficiency.
For high temperature applications, ceramic fiber blankets are extensively employed both inside and outside industrial furnaces. These blankets exhibit exceptional heat resistance, withstanding temperatures ranging from 2190°F (1200°C) to 3000°F (1650°C). Furthermore, due to their adaptable form, they can be easily cut, shaped, and used in conjunction with other products.
Pro Tip: NUTEC insulation fiber blankets offer hassle-free installation, requiring no curing or dry-out time. They enable rapid heat-up, and their outstanding thermal shock resistance ensures they will not crack or spall under extreme conditions.
