E-Glass Yarns
Product Description:
E-Glass fibers are produced in a pultrusion process; by its own weight, the molten glass is conducted through a bushing.
A bushing has multiple hundred holes of which each represents the formation of a filament. All filaments combined form a strand of the final yarn.
Immediately, when the filament is formed, a seizing needs to be applied in order to keep the filaments flexible, prevent them from breakage and protect them for later to come textile processes. The seizings are also designed for the final application and therefore may consist of ingredients such as Acrylic, Parafin, Silane, Starch-Oil, or other.
Besides the choice of the seizing, the End-User also has a choice of various filament diameters and various yarn densities. The choices heavily depend on the final applications and the production steps necessary to develop and produce the desired final end product.
Culimeta E-Glass products are in compliance with ASTM D 578-98, Section 4.2.2.
Chemical Composition:

Basic Yarn Types:
Yarns unprocessed
Yarns Twisted
Yarns Texturized
Rovings
Yarns
Yarns have a very low twist, for protection of the product, Typically they have a lower density and filament diameter.
In most cases, they are the raw material for dyeing, texturizing or twisting,
Yarns Twisted
Yarns are twisted, if one or more strands have experienced a pre-defined number of turns inch or turns meter. In most cases, the final twist is in a S-Direction.
In order to twist two or more yarns in the final S-twist, they need to be pre-twisted in the opposite direction which is called a Z-Twist; this is to balance out the Yarns recall-effect, the desire to twist back into its original form.
Sewing threads have a very high twist, typically in the Z-Direction.
The product can be ring-twisted or direct cabled, assembled, or also called false-twisted. Depending on the final application, the End-User can decide for one of those choices.
Yarns Texturized
In brief, one or multiple strands are mechanically bulked by applying compressed air.
Usually, texturized yarns increase the insulation values of the final product, or contribute to aesthetics in decorative applications.

Rovings
Rovings normally have higher filament diameters and higher densities than the yarns described above. Typically, they have different seizings, more applicable to reinforcement applications.
Nomenclature:
The Letter E in E-Glass stands for excellent electrical properties. For this reason, this fiber is widely used in fabrics, tapes, scrims etc, for electrical insulation applications; in many cases, the fabrics, tapes, etc will need to be treated with chemicals in order to further enhance the electrical insulation values.
As one of the most widely used, it also is one of the most economical of the Glass-Fiber families, It therefore is also commonly used in thermal applications.
The US-Nomenclature e.g. differs from the European Nomenclature.

Basalt Board
Culimeta America offers also a rigid Board made from Basalt Needlemat. This value added treatment allows the material to be dye-cut or molded into almost any common shape.
While the board could be used in almost identical applications as the Basalt Needlefelt is used in, it also allows for additional markets, such as in pipe wrappings, ladles, furnaces, or high temperature insulations, up to approximately 1, 600 degrees F in general.
In highly competitive markets, this board can be used in conjunction with insulation materials of lower K-values, at lower cost. In those instances, the board serves as high temperature facing layer, with the purpose in lowering the temperature far enough for the second layer to withstand. In this example, the second layer could be a fiberglass Needlemat. In other instances, there may be even a third and a fourth layer.
In order to recommend the best insulation system, it will be required to know exactly about the environment this material will be facing.
Applications:
Ovens
Kilns
Furnaces
Whiteware
Transportation
Refractory applications
In general for application up to 1, 600 degrees F

Basalt Chopped Strand Mat
Basalt Chopped Strand Mat in general can be applied where E-Glass, sometimes S-Glass or Carbon Fibers can be used, as well. As Basalt is more expensive than E-Glass, but cheaper than Carbon Fibers, typically it finds implementations, more suitable to its particular properties and fills an important gab when it comes to cost-performance ratios.
You can find a comparison to E-Glass, S-Glass or other materials by clicking here: Basic Comparison To Other Fibers.
Knowing how Basalt compares to other fibers allow to precisely engineer an optimal solution, which could also be in form of a hybrid (combining Basalt with other Fibers made from Glass, Carbon, Kevlar, etc.)
An Example of an Engineered FRP.
In Fiber Reinforcement Products (FRP) the engineer chooses the fiber, based on the desired outcome. E.g. if lighter weight requirements at identical strength to currently used fibers are required or if higher strengths are necessary while staying within the weight specifications.
There are other examples relevant to durability, corrosion resistances, break strength, chemical resistances, thermal applications, etc.
Our Team will be more than glad to assist or consult with design applications.

Silica Mat
Product Description:
Silica Needlemats are made from special glass fibers with a filament diameter of 6-9 microns. They represent a modern product generation that, in any aspect, meets with all stringent requirements as to temperature consistency and environmental health standards. Silica glass fibers consist of nearly 95% SiO(2). Because of their low thermal conductivity they are the ideal raw material for the production of flexible insulation mats formed mechanically without the use of chemical bonding agents. These mats keep a very high chemical and physical stability up to 1, 800 degr. F. (For application temperatures not higher than 1, 200 degrees F, we recommend our more cost efficient E-Glass Needlemat).
The easy handling of the mats allow the cutting of the material into any desired shape and form.
Applications:
Industrial ovens
Chimneys
Kiln furnaces
Boilers
Steel Industry
Gas exhaust systems
Laboratories
Fire protection

Basalt
Culimeta America offers Basalt Fibers and products made thereof.
From Wikipedia, the free encyclopedia, further information about the basalt and its unique properties:
Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to carbon fiber and fiberglass, having better physical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products such as camera tripods.
Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source and unlike other materials such as glass fiber, essentially no materials are added. The basalt is simply washed and then melted.
The manufacture of basalt fiber requires the melting of the quarried basalt rock at about 1, 400 C (2, 550 F). The molten rock is then extruded through small nozzles to produce continuous filaments of basalt fiber.
There are three main manufacturing techniques, which are
centrifugal-blowing,
centrifugal-multi roll and
die-blowing
The fibers typically have a filament diameter of between 9 and 13 m which is far enough above the respiratory limit of 5 m to make basalt fiber a suitable replacement for asbestos. They also have a high elastic modulus, resulting in excellent specific tenacitythree times that of steel.
