It’s as easy as 1-2-3…

We are proud to introduce the first Generation III, Ultra Low Shot fiber in the world. Not as a premium, or only available in a limited productrange, but available in all our Refractory Ceramic Fiber and Low Bio persistence fiber grades. In result, you are getting the best thermal insulation, toughest strength and smoothest handling.

The introduction of the Generation III, Ultra Low Shot technology has proven to be a game changer to those who have been working with the product. ULS technology is delivering you the difference between ‘fit for purpose’ and ‘best in class’.

Smoother and stronger blankets, higher yield of bulk fiber in vacuum forming processes, better machinability on boards, higher resiliency after compression of fiber modules and cleaner cut gaskets from our papers and felts. The key to these improvements is the higher fiber index and lower shot contents. Let us explain what makes us so enthousiastic about Ultra Low Shot technology fibers…

 

Best Thermal Insulation

The higher the fiber index the better the high temperature fiber will perform. Key factors to improve the fiber index are minimizing the shot content and optimizing fiber diameter.

Vulcor ULS technology combines these key factors and as a result delivers you the best thermal insulation properties in high temperature fiber products. You can optimize your lining thickness or reduce your energy consumption as well as your CO2 emissions.
Go Green!

 

Toughest Tensile Strength

The superior fiber index and needling technique give the ULS technology fiber products a higher mechanical strength. Higher mechanical strength results in product that can withstand higher gas velocities.

In case the product is used as a seal it will ensure the joint is closed, or in case of module making it withstands higher compression, and still maintains its resiliency.

Superior Handling

When you are installing fiber material it can be pretty annoying working with products that disintegrate and give off lots of dust. These are common cases of poor needling of fiber blankets.

The interlocking of the fibers from needling is highly increased by the fiber index as a result of the ULS technology. A smooth surface of the fiber blanket reduces the skin irritation, and makes working with fibers easy as 1-2-3…

 

Best Thermal Insulation

Thermal insulation restricts the flow of energy with respect to:

· Thermal radiation

· Thermal conduction

· Thermal convection

For high temperature insulation thermal radiation is the dominant form of energy transfer above 400°C and even more applicable for low density high temperature fiber products.

Fiber structures block radiation by having a large number of surfaces. As the radiation interacts with each surface, which becomes hot and will re-emit radiation (at a lower intensity) in all directions, and so transfer through the fiber structure is restricted.

For this reason the high fiber index, which also results in more surface area to interact with thermal radiation, is not only important from a strength or handling perspective, but it also delivers better thermal insulating properties.

Independently tested the SoliBlanket ULS-grade outperforms the ‘best in class’ Generation I and Generation II fiber products with up to 30% improvement on thermal conductivity.

For SoliBlanket X-grade (refractory ceramic fiber), compared to its ‘peers’, the difference in measured thermal conductivity, is up to 42% in favour of  our Ultra Low Shot technology.

Toughest Tensile Strength

High temperature fiber blankets are ‘needled’ to convert from a fleece to a blanket. During the needling process, interlocking for the fibers in the fiberstructure is achieved. High fiber index and advanced needling technology are crucial to achieve the toughest tensile strength.

In addition to tensile strength, delamination strength, and resiliency are improved. All together, even thou these other properties are not typically mentioned on a datasheet could be considered the mechnical strength of a blanket.

Why is high mechnical strength relevant?

Not only does it affect the handling, but higher mechanical strength also means that the product can withstand higher gas velocities, both parallel and perpendicular to the dominant fiber
orientation.

But the most relevant strength features next to the tensile strength, is the resiliency of the blanket. The resiliency is the % of ‘spring back’ in a relax state after compression perpendicular to the main fiber orientation.

Internal  testing confirm that the pre-load to achieve 50% thickness compression for our Ultra Low Shot, Generation III blankets is up to 42% higher, but even then the resiliency, or spring-back remains 18% higher compared to Generation I blankets.

 

 

Superior Handling

The last feature resulting from the Ultra Low Shot technology is the least easy to quantify in numbers..

How do you define less fiber dust working over head installing the product in the roof of a furnace?? Be assured you the installation team installing the blankets can tell you the difference.

Better interlocking of fibers, higher fiber index, lower shot content, all result in superior handling of the blanket we are supplying to the market.

  • Less dust working over head (roof of furnace)
  • No tearing or breaking of the blanket during installation (which is typically the case with thin blankets and low density products)
  • No soft spots and even thickness distribution over the width of the blanket.
  • Smooth surface resulting in less skin irritation
  • No loose felt on the folds of blanket strips or modules

The ULS technology means better fiber, higher fiber index, advanced needling, less dust from the product, and in result less skin irritation and better handling.

Vulcor Insulation is innovating the market

We might have introduced ourselves as the New Kid in town, but our team has been in the industry for many years. We have been making industrial insulation solutions for many years, but why having thoughts on how to make good products even better and not acting? This has been the main reason to start our journey.

Now we are offering a full product range of high temperature insulation products, and the stars of our range are the SoliWool products. To explain how innovative these products are, we would like to introduce you to this little timeline for high temperature fiber products.

The beginning

The rise of RCF fibers

In the 1960s Refractory Ceramic Fiber products were commonly accepted in the market as alternative to other types of fiber for high temperature applications.

1960
Generation one

The first low bio persistence fibers

By 1989, so more than 30 years ago, the first low bio persistence fibers, or Alkaline Earth Silicate fibers were introduced to the market. All these products were manufactured in Generation I technology.

1986
Generation two

Low Shot Blankets

In 2006 the first large manufacturer introduced a ‘low shot’ or Generation II fiber product. This product was offering better handling and thermal insulating properties, compared to the inferior Generation I fiber products which, EVEN TODAY, are offered in the market.

2006
Generation three

ULS technology is born

And today, more than 30 years after the introduction of the Generation I low bio persistence fibers, we launch our Generation III, Ultra Low Shot technology, products. Our products are offering the best thermal insulation, highest strength and superior handling The ULS technology is not limited to Low Bio persistence fiber only…
