In November 2025, Halo Butyl Rubber prices in North America rose slightly by 0.8% amid steady demand and moderate inventory flows. Production rates were stable but cautious, as limited supplies of feedstock, Isobutylene, and volatility in the crude oil market added pressure on the product production costs. Export rates showed cautious stability, with diversified trade routes and firm overseas demand helping balance risks. At the same time, Halo Butyl Rubber demand remained steady but limited in the U.S., shaped by consistent activities in the automotive and construction sectors. Automotive use continued in tire inner liners, sealing systems, and vibration-dampening parts. Construction demand was also stable as high costs and weak residential activity restrained volumes. Prices are expected to rise further in the coming weeks as inventories remain tight due to production slowdown during winter. Additionally, shipping delays and an increase in energy and raw material costs will add pressure to the product prices.
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.
