Phase change materials market seen reaching $4.51 billion by 2035

Market Research Future projects the global phase change materials market will grow from about $0.98 billion in 2025 to $4.51 billion by 2035, driven by demand for energy efficiency, electric vehicles, cold-chain logistics and data-center cooling. Europe leads today, while Asia-Pacific is expected to be the fastest-growing region.

Why it matters: - Phase change materials are moving from niche thermal-storage products into mainstream applications across buildings, transport, logistics and electronics. - The market outlook points to rising demand for technologies that can cut energy use, stabilize temperatures and support decarbonization goals. - PCM adoption could affect how buildings manage heating and cooling, how EV batteries are protected, and how temperature-sensitive goods are shipped.

What happened: - Market Research Future valued the global phase change materials market at about $0.98 billion in 2025. - The firm projects the market will reach $4.51 billion by 2035. - The forecast implies a 16.4% CAGR from 2026 to 2035. - The report was published in New York on Sept. 9, 2026.

The details: - Phase change materials absorb, store and release thermal energy as they move between solid and liquid states. - The materials store latent heat within a narrow temperature range, unlike conventional materials that mainly store sensible heat. - Common PCM categories include organic, inorganic, bio-based and eutectic mixtures. - Typical chemical compositions include paraffins, salt hydrates, fatty acids, esters and sugar alcohols. - Buildings are one of the largest applications, with PCM components used in walls, ceilings, floors and insulation systems. - The building and construction sector accounted for 36.4% of the PCM market in 2025. - Organic PCMs accounted for about 40.8% of market revenue in 2025. - Macro-encapsulation generated about $0.59 billion in revenue in 2025. - Europe held about 30.2% of global revenue in 2025. - North America held about 28.6% of the market in 2025. - Asia-Pacific is projected to grow at a 17.3% CAGR through 2035. - Bio-based products are projected to grow at about 17.6% CAGR through 2035. - EV battery-pack applications are growing at about 18.2% annually, according to the report. - Cold-chain logistics and pharmaceutical shipping generated about $0.19 billion in PCM revenue in 2025. - The report identifies Phase Change Solutions Inc., Croda International plc, Honeywell International Inc., BASF SE, Outlast Technologies LLC and Rubitherm Technologies GmbH as major companies in the market. - The market can be analyzed by product type, chemical composition, encapsulation technology, end-user industry and geography. - Encapsulation methods include macro-encapsulation, micro-encapsulation, nano-encapsulation and shape-stabilized composites.

Between the lines: - The strongest growth themes are tied to energy costs, building-efficiency rules, electric mobility and the expansion of cold-chain and data-center infrastructure. - Bio-based PCMs stand out because sustainability goals are pushing buyers toward renewable feedstocks. - The report suggests PCM technology is shifting from passive thermal buffering toward more integrated energy-management systems in smart buildings and grid-interactive buildings. - The competitive field is likely to favor companies that can improve performance while lowering encapsulation cost, material instability and fire-safety concerns.

What's next: - Europe and North America are likely to keep driving near-term demand through efficiency standards, utility demand response and advanced building systems. - Asia-Pacific is expected to become the fastest-growing regional market as construction, EV production and electronics manufacturing expand. - Emerging opportunities are concentrated in smart buildings, grid-interactive buildings, pharmaceutical logistics and district cooling. - Market adoption will depend on progress in lower-cost encapsulation, improved cycling stability and safer formulations. - More information is available in the full report.

The bottom line: - Phase change materials are on track for rapid growth because they solve a practical problem: keeping temperatures stable while cutting energy use.
