Specialty Chemicals: Flame Retardants, Additives, Catalysts, Industrial Gases, Chlor-Alkali and Separation Media

Specialty Chemicals: Flame Retardants, Additives, Catalysts, Industrial Gases, Chlor-Alkali and Separation Media

The Chemistry Behind Electrification, Decarbonization, Data Centers and Clean Water

Mobility Foresights Chemicals & Materials Research | Hub Analysis | September 2026

Specialty chemicals are sold in small volumes but determine whether much larger systems work. A flame retardant decides whether a battery pack passes safety testing. A catalyst decides whether sustainable aviation fuel is economic. A membrane decides whether a desalination plant meets its energy target.

Three forces are reshaping the sector:

  • Regulation. Proposed EU-wide PFAS restrictions, HFC refrigerant phase-downs and biocide rules are forcing reformulation across many product lines.
  • Decarbonization. Hydrogen, carbon capture, sustainable fuels and green ammonia all depend on new catalysts and industrial gases.
  • New end markets. Electric vehicles and AI data centers have created demand for thermal management fluids, dielectric materials and ultra-pure chemicals.

This hub brings together 98 Mobility Foresights market studies across eight areas: flame retardants; polymer additives, fillers and pigments; catalysts; industrial gases; chlor-alkali, bromine, intermediates and solvents; surfactants, antifoams and biocides; refrigerants and thermal fluids; and adsorbents, membranes and separation media.

Key Takeaways

  • PFAS restriction is the largest reformulation event in decades. It affects flame retardants, refrigerants, coolants and processing aids simultaneously.
  • Catalysts are the enabling technology of the energy transition. Hydrogen, SAF, renewable diesel and green ammonia each depend on catalyst performance and cost.
  • Industrial gases are becoming decarbonization infrastructure. Carbon capture, low-carbon ammonia and hydrogen supply are reshaping the gas business.
  • Data centers are a new specialty chemicals market. Immersion coolants, thermal interface materials and ultra-pure water chemistry are growing quickly.
  • Separation media underpin water and hydrogen. Membranes, adsorbents and ion-exchange resins are shared technology across desalination, gas purification and electronics.

1. Flame Retardants

Flame retardants are being reformulated on two fronts: away from halogenated chemistry in many applications, and toward the specific requirements of electric vehicles and energy storage. Four reports cover the halogen-free shift:

Application-specific and reactive systems:

2. Additives, Fillers and Pigments

Recycled plastics need additives to restore properties lost in reprocessing, making this one of the fastest-growing additive segments. Four reports cover it:

General additive markets:

Fillers and pigments:

3. Catalysts

Catalysts make reactions possible at practical temperatures and yields, so they largely determine whether a clean-energy process is economic. Five reports cover hydrogen and clean fuels:

Carbon and nitrogen chemistry:

Refining, petrochemicals and emissions:

Process efficiency and specialty catalysis:

4. Industrial Gases

Industrial gas companies have become central to decarbonization projects because they already own the infrastructure for handling hydrogen, oxygen, nitrogen and carbon dioxide. Five reports cover the segment:

5. Chlor-Alkali, Bromine, Intermediates and Solvents

Chlor-alkali is one of the most energy-intensive chemical processes and produces chlorine and caustic soda together, so their markets are linked. Six reports cover the family:

Bromine and specialty intermediates:

Solvents and green chemistry:

Bio-based and lower-carbon chemistry:

6. Surfactants, Antifoams and Biocides

Surfactants are core to cleaning and personal care, and consumer preferences have shifted toward milder chemistry. Four reports cover them:

Antifoams and process aids:

Preservation and microbial control:

7. Refrigerants and Thermal Fluids

The HFC phase-down under the Kigali Amendment and regional F-gas rules is forcing a transition to lower global-warming-potential refrigerants. The next-generation HFO refrigerants market report covers HFO refrigerants and the tension between climate performance and the PFAS classification some of them face.

Regional perspective

  • Europe. The strictest regulation and the origin of the PFAS restriction proposal, with high energy costs pressuring chlor-alkali and gases.
  • United States. Advantaged feedstock and strong investment in hydrogen, CCUS and SAF catalysts.
  • China. The largest production base for additives, intermediates and chlor-alkali, and increasingly for catalysts.
  • Middle East. Low-cost feedstock supporting petrochemicals, ammonia and emerging low-carbon hydrogen projects.

What to Watch Through 2032

  1. PFAS restriction scope: which uses receive exemptions and for how long.
  2. Electrolyzer catalyst loading: reducing platinum-group metal use to cut hydrogen costs.
  3. SAF mandates: blending requirements driving catalyst and gas demand.
  4. Data center chemicals: growth of immersion coolants and thermal interface materials.
  5. Biocide re-registration: European reviews removing active ingredients from the market.

Frequently Asked Questions

Why are flame retardants being reformulated?

Regulatory pressure on halogenated and fluorinated chemistry, combined with smoke-toxicity requirements and the specific demands of EV batteries, is driving a shift toward halogen-free, fluorine-free and reactive flame retardants.

How do catalysts affect the energy transition?

Catalysts determine the efficiency, selectivity and cost of hydrogen production, sustainable aviation fuel, renewable diesel, ammonia and carbon conversion. Improving them, and reducing precious-metal content, is central to making these processes economic.

What is driving demand for industrial gases?

Beyond traditional industrial uses, decarbonization projects need hydrogen for steel, oxygen for oxy-fuel combustion, and CO2 capture and transport, making industrial gas companies key infrastructure providers.

Why are data centers a specialty chemicals market?

High-density AI servers require immersion coolants, thermal interface materials and ultrapure water chemistry, creating demand for specialty fluids and materials that did not exist at this scale before.

What are HFO refrigerants?

Hydrofluoroolefins are refrigerants with much lower global warming potential than the HFCs they replace. Their adoption is driven by the Kigali Amendment and regional F-gas regulations, though some face scrutiny under PFAS rules.

What are chelating resins used for?

Chelating resins selectively bind specific metal ions, allowing removal of heavy metals from water or recovery of valuable metals from process streams and recycling operations.
