Our markets
Custom chemistry for every industry.
At SEQENS, we turn your market‑specific challenges into reliable, scalable and sustainable custom chemical solutions. Whether you need to develop a new molecule, secure a strategic chemical intermediate, improve the performance of an existing formulation, or accelerate your transition toward greener and lower‑impact processes, our teams support you from early‑stage development to full industrial scale‑up and multi‑ton manufacturing.
Across demanding sectors—including batteries, coatings, cosmetics, electronics, lubricants, polymers, oil & gas, defence and aerospace—we design, optimize and industrialize the tailor‑made molecules, specialty ingredients and high‑purity intermediates that power your innovation. Our expertise spans complex organic synthesis, high‑purity building blocks, functional performance additives and next‑generation sustainable chemistries.
• Electrolytes & Additives: Tailor-made organic molecules and functional salts.
• Cathode & Anode Materials: Custom binders, monomers, solvent molecules, and intermediates
• Precursors intended for the recycling of active materials

• Ethers: they widely used in the production of plastics and rubber due to their chemical stability and low reactivity, which facilitate their incorporation into polymer formulations. They also enhance the flexibility, solubility, and processability of resins.
• Active ingredients: Anti-aging, whitening agents, UV filter
• Fragrances s: Ketones, carboxylic acids
• Polymers
• Partnership: We partner with several start-up companies to support innovation in custom manufacturing project.
• Process optimization: The use of renewable raw materials, solvent recycling, energy and water consumption or waste management are some of the key criteria to the evaluation of custom manufacturing projects.
• Phosphorus chemistry: phosphorus compounds such as phosphites, ester phosphates, and phosphonates are mainly used as antiwear additives. They can also be used as pharmaceutical intermediates and flame retardants in the coating industry.

• Anionic surfactants : they reduce surface tension and enhance wetting, dispersion, and detergency thanks to their negatively charged hydrophilic group. They are therefore essential components in cleaning products, emulsions, and dispersed systems across a wide range of industrial applications: alkylbenzene sulfonates or sarcosinates.
• Calcium sulfonate chemistry : corrosion protection additives and greases Based on a unique one-step carbonatation process, we can propose fully customizable calcium sulfonate products supporting the performance and sustainability needs of our customers.
