For lighter vehicles with lower fuel consumption and emissions, composite materials are an innovative alternative to metal and solid plastic structures. Our SolvaLite™ composites are up to 40% lighter than metal and cure much faster than traditional composites. A step-change from traditional composite materials, it also means more efficient, much faster production and enhanced cost effectiveness in high-volume production runs.

Solvay is also uniquely positioned in thermoplastic composites with the best-in-class portfolio in specialty polymers and strong expertise in composite technologies. These materials are expected to play an increasingly important role in meeting growing demand for lighter components and reduced aircraft construction time. From world-leading commercial airplane manufacturers to space exploration programs, Solvay serves the entire aerospace industry, providing innovative aerospace composite solutions from airframes to interiors, electrical, air and fluid systems and propulsion.


Batteries with higher energy density, enabling faster charge with greater power and lower cost, are vital to the future of electromobility. Solvay is at the cutting edge of battery innovation with solutions that meet the highest safety, temperature and chemical resistance requirements, and so address the needs of the entire battery system. Our fluorinated materials for advanced lithium-ion (Li-ion) batteries and our Energain® technologies enable the operation of next generation Li-ion batteries at higher voltage for higher energy density.

Powertrain efficiency

In all types of powertrains, the engine and transmission system offer significant potential for energy efficiency improvements. Our specialty polymers, like our thermoplastics product ranges Amodel® PPA and Ryton® PPS, help to build lighter and so more fuel-efficient internal combustion engines, manage the intense heat of down-sized engines, and develop hybrid electric vehicles that combine gasoline engines and electric motors in order to achieve the best balance of fuel economy and demand on batteries.

Green technologies

Our silica products designed for tire manufacturers can reduce rolling resistance by up to 25%, for 7% lower fuel consumption. Indeed, they make tire gum more consistent and prevent it from heating up, thus decreasing the rolling resistance of tires and keeping them safe for longer. Our latest innovative grade Premium SW is among the cheapest and most efficient ways to cut CO2 emissions from vehicles. Several Solvay solutions, including Autocat® are used in automotive catalytic converters to minimize pollutant emissions while boosting performance.


Precision solutions for aircraft

With our Cycom® range of products, we offer solutions for the most technically challenging composite applications. Cycom® prepregs and resin systems are the industry standard for stiffness, impact resistance and thermal performance. This innovation delivers 10 to 20 times faster manufacturing rates, thus enabling a lower total cost of ownership in line with industry expectations for high volume composite use.

Multi-skilled polymer

A high-performance material for Li-ion batteries, our Solef® PVDF has been awarded the Efficient Solutions label by the Solar Impulse Foundation. This polymer is used to manufacture battery components (binders and separators). As a partially fluorinated material, it is particularly stable, for enhanced safety performance. It enables higher voltages and high-temperature resistance – key for electric vehicle batteries – faster charge and fire-resistance.

Evolite™ F1050 is a high-performance thermoplastic composite material specially designed for oil & gas. It combines the excellent chemical and temperature resistance of Solef® PVDF with the inherent high strength performance of carbon fiber. It offers both the mechanical reinforcement of steel and lower weight, potentially saving dozens of tons on a single pipe.

Clean technologies

Solvay has developed a range of solutions for renewable energy production. In solar power, our innovations include protective films for photovoltaic panels, and our wind power solutions range from seals and cables to epoxy compounds for wind turbine blades. Our solutions to support air and water treatment and soil remediation, addressing the requirements of more challenging regulations, use filtration, gas separation, absorption, and chemical reactions. Our Capterall®* mineral-based solutions efficiently remove pollutants from wastewater, helping our customers comply with strict regulations.


High-performance, high sustainability

Mining operations choose the Aerophine® family of reagents for their ability to promote high recoveries and improve selectivity in complex flotation – a technique used to separate minerals – across base and precious metal ores. Aerophine® offers enhanced sustainability over competing reagent chemistries, with reduced dosage rates and enhanced stability. It also avoids the formation of hazardous decomposition products.

A cleaner, safer environment

Solvay’s Solvair®* range treats the gases emitted by multiple industries and municipal activities, such as energy-from-waste incinerator or industrial boilers. One of our solutions, Solvair® Marine, is particularly innovative. This sulfur oxide scrubber system complies with all existing and upcoming regulations, removes 99% of particles, does not release wastewater back to the sea and can be installed without dry docking. It also facilitates residue treatment on land.
