Nexam vs. Perstorp
One sells building blocks to formulators, the other a finished masterbatch to converters. Where the two Swedish chemical companies touch, and where they never meet.
Both are Swedish specialty chemical companies working on plastics, and both talk about circularity. That is where the similarity ends, and the difference is the useful part.
Where they do not compete
Perstorp sells building blocks. Its performance polymer additives page offers specialty polyols and acids that "enable multifunctional additives", along with Holtac heat stabilizer components for calcium and zinc systems in PVC, Charmor carbon donors for non-halogen flame retardancy, and Akestra, an amorphous copolyester. Nothing on that page is a chain extender, a masterbatch, or a product dosed into mechanically recycled thermoplastic.
Nexam Chemical sells the finished additive, as a masterbatch, to the converter who runs the recycled material. One company sells to formulators, the other to processors. A converter buying NEXAMITE is not choosing it over a Perstorp polyol; those are different lines in a different budget.
Where they touch
Two places, neither of them head-on.
- Recycled and renewable feedstock. Perstorp's Pro-Environment range is chemically identical to the fossil version but made from recycled or renewable raw material under ISCC PLUS mass balance. That is circularity in the feedstock, whereas Nexam's business is circularity in the polymer that is already in use. Both sell into the same regulatory weather.
- Packaging design. Perstorp positions Akestra as a copolyester that enables PET recycling for hot-fill food packaging. Making a package easier to recycle and making recyclate easier to process are complementary, not competing.
The size difference is not visible from Perstorp's side
Perstorp has been a wholly owned subsidiary of PETRONAS Chemicals Group since 2022 and, since 2025, part of that group's specialty chemicals division. It stopped publishing separate annual reports from 2022, so its revenue and headcount are no longer public at company level. It operates plants across Sweden, the Netherlands, Germany, Italy, India, the United States and China, and announced in September 2026 that it would discontinue production at its Toledo facility.
Nexam Chemical reported 60.0 MSEK of net sales in the second quarter of 2026 and its first positive operating result. The two are not in the same size class, and since Perstorp no longer reports separately, a reader cannot put a ratio on it from public sources.
What to watch
If Perstorp ever launches a reactive additive for mechanically recycled polyolefins or polyesters, that is a genuine competitive event, and its scale and customer access would matter immediately. Nothing on its site today indicates it. The more likely interaction stays indirect: both benefit from the same recycled content mandates, and Perstorp's mass balance route competes for the same sustainability budget inside a customer.
