On November 7, 2025, the price of Diisopropyl Ether (DIPE) in USA remained stable, which absorbed the 0.38% increase in the underlying feedstock Isopropyl Alcohol, which was indicative of decreased supplier pressures. Domestic production inventory was supplemented by imports that provided a stable supply foundation with tariff negotiations about tariffs likely reaching 100% on pharmaceuticals and intermediates leading to a short-term unknown. The global production growth was continued at 1.9% for 2025 due to chemical demand being higher on a weak demand in broader downcycle in the U.S in 2025 instead of inability to end-markets. A limited amount of export delays to Mexico, Japan, and Costa Rica were still related to systems problems and congestion in the Houston port, with vessels still waiting an average of 1.83 days with high yard density.
Selenis has effectively manufactured recycled PET chips using terephthalic acid sourced from Circ®, a textile-to-textile recycler based in Virginia. The chip production took place through a series of batches at Selenis' pilot plant in San-Giorgio, Italy. By utilizing inputs recovered from polycotton textile waste, Selenis has created high-quality PET chip, which has been further processed into DTY yarn. This yarn will play a crucial role in product development as Circ prepares for additional capsule launches. Selenis is leveraging the success of this initial collaboration phase and is committed to advancing towards an offtake partnership to support Circ's inaugural industrial facility.
Eduardo Santos, Head of Corporate Strategy at Selenis, remarked that the monomer synthesis showed a performance comparable to virgin terephthalic acid. He expressed optimism about the consistent quality of Circ's monomer output and anticipated future commercial success. Santos pointed out that the Circ partnership complements Selenis's existing mission and goals for a more sustainable textile industry. He further stated their anticipation of expanding upon this collaboration and providing support for Circ's forthcoming commercial production trials.
