The AI boom is turbocharging demand for PFAS—per- and polyfluoroalkyl substances, better known as “forever chemicals.” According to a new ChemSec report, most of the big PFAS producers are gearing up to expand capacity. The spike in demand is coming from data centers, semiconductor manufacturing, and materials for lithium-ion batteries.

Why PFAS Matter for AI Infrastructure

PFAS are super heat-resistant, so they’re critical in cooling systems, chip production, and Li-ion battery materials. That makes them essential for scaling up the computing power behind today’s AI models and the data centers that run them.

Producers Plan to Ramp Up Output

The ChemSec report says most major PFAS players are planning to boost production, targeting the growing needs of data centers, the semiconductor industry, and battery supply chains. The report doesn’t give exact timelines or details on how much capacity will increase.

The Environmental Side of 'Forever Chemicals'

PFAS are called “forever chemicals” because they’re incredibly persistent—many break down extremely slowly in the environment, and some can build up in living organisms. As demand accelerates, how to handle and replace PFAS is coming under serious scrutiny.
