Miralon: Conductivity at a Fraction of the Carbon Black Loading

Miralon is Huntsman’s line of carbon nanotube materials, made in San Antonio, Texas. It brings electrical conductivity, ESD protection, EMI shielding, and mechanical reinforcement to resins, coatings, adhesives, and thermoplastics at loading levels far below what carbon black or graphite need to do the same job. Under 2% Miralon typically does the work of 15% to 20% carbon black.

That loading difference is the whole story. Less filler means you keep your viscosity, your mechanical properties, your part weight, and in most formulations, your color. Chemical Concepts supplies Miralon as pulp, sheet, tape, yarn, masterbatch, and dispersions for formulators, compounders, molders, and OEMs.

+Miralon vs Carbon Black

Carbon black and graphite work. Most formulators use them today. The reason to look at Miralon is what happens to the rest of your formulation once you stop loading 15% to 20% filler into it.

Property Miralon Carbon Black / Graphite
Loading for conductive or ESD performance Typically under 2% Typically 15% to 20%
Finished color Colored conductive systems are possible at low loading Black or dark gray only
Wet-state viscosity Low impact at working loadings Significant increase, harder to pump, mix, and dispense
Mechanical properties Up to 142% modulus increase at 4% in thermoplastics, strain at break maintained High loading levels typically cost strength and toughness
Dispersion stability No settling at 24 months in a Bisphenol A masterbatch Settling in cartridges and drums is a common field complaint
Molding shrinkage 0.5% in PA12 cut molding shrinkage by 50% in customer testing No comparable effect
Part weight Lower filler load, lighter finished part Filler load adds weight
Supply Made in the USA (San Antonio, TX) Widely available, most competing CNT supply is offshore

In Huntsman’s own conductive epoxy work, ARALDITE GY 40100 (a Bisphenol A resin with Miralon already dispersed into it) matched the electrical performance of a carbon black loaded control at 20 to 100 times lower filler concentration, with a much smaller viscosity penalty.

Carbon black is still the right call when you only need black pigment or rubber reinforcement. The switch makes sense when the loading itself is causing you problems: viscosity, brittleness, weight, settling, or a color spec you cannot hit.

+Conductive Without Going Black

This is the point that surprises most people, and it is worth its own section.

A carbon black loaded coating or compound is black. At 15% to 20% loading there is no other outcome. If the finished part, panel, or floor has to be light gray, white, safety yellow, or a customer’s brand color, carbon black takes that off the table and you end up choosing between the ESD spec and the appearance spec.

Because Miralon works at under 2%, there is room left in the formulation for pigment. That opens up:

  • Light gray, white, and colored ESD floor coatings for data centers, semiconductor fabs, battery plants, and clean production areas
  • Colored static-dissipative housings, totes, trays, and packaging where the part also has to look right
  • Line marking, zoning, and safety color inside static-controlled areas without breaking the conductive network
  • Conductive adhesives and potting compounds that do not have to read as black on a visible bond line

If you have ever been told a job has to be black because it has to be conductive, that is the conversation to have with us.

+What Miralon Is and How It Is Made

Miralon is a carbon nanotube material produced by Huntsman Advanced Materials using a floating catalyst chemical vapor deposition (FC-CVD) process. Huntsman acquired the technology from NanoComp Technologies in 2018 and now produces it in San Antonio, Texas.

Three carbon nanotube structures matter when you are specifying a conductive filler:

  • Single-wall CNT. Highly conductive, expensive, lower strength.
  • Multi-wall CNT. Stronger and cheaper, lower conductivity.
  • Miralon. A bundled, few-wall structure. The long interconnected bundles create multiple contact points, so you get high conductivity and high strength out of the same material instead of trading one for the other.

Individual tubes are thinner than a human hair and up to 25 times stronger than steel by weight. In practice you are not handling individual tubes. You are handling pulp, dispersions, masterbatch, sheet, tape, or yarn.

The process, and why US supply matters

FC-CVD splits natural gas or another hydrocarbon feedstock into two useful outputs: solid carbon nanotube material and clean hydrogen. It does not generate the large volumes of carbon dioxide associated with conventional steam methane reforming, so there is no carbon capture cost attached to it. An MIT environmental study conducted under an ARPA-E supported project found the Miralon process reduced the CO2 footprint of clean hydrogen production by as much as 95% compared to steam methane reforming.

On supply: most carbon nanotube material on the market today comes from China, Russia, and Korea. Miralon is made in the United States. For buyers dealing with onshoring requirements, defense content rules, or tariff exposure on offshore fillers, that is a practical reason to look at it, separate from the technical case. Huntsman’s San Antonio plant is running and scaling now, and pricing has come down significantly from historic CNT norms.

+Handling, Dispersion, and Safety

Dispersion is the job

Getting CNT performance out of any form starts with getting it properly dispersed. That is why masterbatch and pre-dispersed resin forms exist. If you are compounding or formulating from pulp, talk to us about equipment and method before you buy. A poor dispersion looks like a product failure when it is actually a process problem.

Airborne exposure

Miralon’s bundled morphology makes it far less likely to become airborne than conventional powder CNT. Pre-dispersed resin forms remove dry powder handling from the process entirely. In most end uses the material ends up encapsulated in a cured resin or bound into a thermoplastic.

Documentation

SDS and technical data are available for every form we supply. Send specific regulatory or EHS questions to us and we will route them to Huntsman’s technical team rather than guess at the answer.

+Miralon FAQ

What is Miralon?

Miralon is a carbon nanotube material made by Huntsman Advanced Materials in San Antonio, Texas. It has a bundled few-wall structure that combines the electrical conductivity of single-wall carbon nanotubes with the strength of multi-wall carbon nanotubes. It is supplied as pulp, dispersion, masterbatch, sheet, tape, and yarn, and it adds conductivity, ESD protection, EMI shielding, and mechanical reinforcement to resins, coatings, adhesives, and thermoplastics.

Is Miralon a replacement for carbon black?

In conductive and static-dissipative formulations, yes. Miralon typically delivers the same conductivity as 15% to 20% carbon black or graphite at under 2% loading. The lower loading is what buyers are actually after: less viscosity increase in the wet state, better mechanical properties in the cured state, lighter parts, and the ability to pigment the finished system. Carbon black remains the right choice where you only need black pigment or rubber reinforcement.

How much Miralon do I need compared to carbon black?

As a working figure, under 2% Miralon does the conductivity work of 15% to 20% carbon black or graphite. In Huntsman’s conductive epoxy resin work the gap was wider, matching a carbon black control at 20 to 100 times lower filler loading. Actual loading depends on your resin system, target resistivity, and dispersion method, so run a trial before you lock a formulation.

Can you make a colored conductive or ESD coating with Miralon?

Yes, and this is one of the main reasons formulators move off carbon black. A carbon black loaded system at 15% to 20% is black and cannot be anything else. Miralon works at under 2%, which leaves room in the formulation for pigment. That makes light gray, white, and colored ESD floor coatings, housings, totes, and packaging possible without giving up the static-dissipative spec.

What is the difference between Miralon and single-wall or multi-wall carbon nanotubes?

Single-wall CNT is highly conductive but expensive and lower in strength. Multi-wall CNT is stronger and cheaper but less conductive. Miralon is a bundled few-wall structure. The long interconnected bundles create multiple contact points, so it delivers high conductivity and high strength in the same material rather than forcing a trade between them.

Where is Miralon made?

Miralon is made in the United States by Huntsman Advanced Materials at its San Antonio, Texas plant, using a floating catalyst chemical vapor deposition process. Most carbon nanotube material on the market is produced in China, Russia, or Korea, so Miralon is the domestic option for buyers with onshoring, defense content, or tariff exposure concerns.

Which Miralon form should I use?

Pulp is the dry additive for formulating and compounding. Dispersion is for wet processes and battery slurries where dry powder handling is not practical. Masterbatch is for injection molding and extrusion in PA6, PA12, PETG, or PPS. Sheet is for surface ESD and EMI shielding layers on composites. Tape is for EMI seams, conductive bonding paths, and lightning strike protection. Yarn is for lightweight conductors and reinforcement. If you are not sure, send us the application and target resistivity and we will point you at the right form.

Will Miralon settle in a cartridge or a resin drum?

Settling is the standard complaint with carbon black filled systems. Miralon’s bundled morphology resists it. Huntsman has a Bisphenol A epoxy masterbatch with Miralon that showed no settling at 24 months. If cartridge settling or drum stratification is a current problem for you, that is worth a conversation.

Can Miralon be used in ESD flooring?

Yes. Miralon is used as the conductive additive in epoxy and urethane floor coating systems for data centers, semiconductor fabs, battery plants, and electronics assembly areas. The advantages over carbon black filled ESD floors are lower loading, better mechanical and wear performance in the cured film, and the ability to specify a color other than black or dark gray. We work with epoxy floor coating formulators looking to add an ESD line.

Does Miralon work in thermoplastics?

Yes. Miralon conductive masterbatch is available in PA6, PA12, PETG, and PPS carriers at 15% CNT for injection molding and extrusion, and Miralon has been evaluated in PEI and PEEK. Beyond conductivity, 4% loading increased modulus by up to 142% without sacrificing strain at break, and 0.5% in PA12 cut molding shrinkage by 50% in customer testing, which matters on precision parts.

Is Miralon safe to handle?

Miralon’s bundled structure makes it far less likely to become airborne than conventional powder carbon nanotubes, and pre-dispersed resin and masterbatch forms remove dry powder handling from the process. In most end uses the material is encapsulated in a cured resin or bound into a thermoplastic. SDS documentation is available for every form we supply, and specific regulatory questions go to Huntsman’s technical team.

Can I get a Miralon sample?

Yes. Evaluation quantities are stocked and listed on this page: pulp from 1 g, sheet from a 4 in x 4 in sample, yarn from 1 ft, tape from 1 ft. For formulated systems, masterbatch trials, or anything needing a technical recommendation, send us your application, current material, and target performance and we will coordinate the right sample and technical support.

Send us the application, the material you are running now, and the problem you are solving. Target resistivity, substrate, process, and volume all help. We will get you the right form, the data, and technical support from Huntsman where the application calls for it. Contact Chemical Concepts or call 800-220-1966.
