Polytetramethylene Ether Glycol (PTMEG) prices in Germany, the highest-cost reporting region, rose 5.8% in H1 2026, climbing from USD 3.42/KG in Q1 to USD 3.62/KG by Q2 as spring spandex fibre and thermoplastic polyurethane demand and firmer tetrahydrofuran feedstock costs supported the market following the brief Q3 2025 softening. Globally, the average rose from USD 2.493/KG in Q1 to USD 2.618/KG in Q2, a 5.0% gain. For H2 2026, a global average of USD 2.64-2.90/KG is expected, with continued firming on Middle East supply disruptions and growing spandex fibre and polyurethane elastomer sector demand.
Polytetramethylene Ether Glycol (PTMEG), commonly abbreviated as PTMEG or PTMG, is a polyether glycol produced through the ring-opening polymerisation of tetrahydrofuran using a strong acid catalyst, yielding a waxy solid or viscous liquid with a molecular weight range of 650 to 3000 daltons. The largest pull comes from spandex and elastane fibre production, where PTMEG is reacted with an isocyanate component to form the soft segment of polyurethane fibre for sportswear, activewear, hosiery, and stretch textile applications. Additional demand comes from thermoplastic polyurethane elastomer production for automotive and industrial applications, polyurethane cast elastomers for mining and oil drilling equipment, adhesive and sealant formulations, and high-performance polyurethane coating systems. Tetrahydrofuran and butanediol feedstock costs, spandex fibre and polyurethane sector demand, and regional polymerisation capacity all feed into the price.
The balance of supply and demand for Polytetramethylene Ether Glycol (PTMEG) through H2 2026 leans moderately firm. Tetrahydrofuran and butanediol feedstock costs firmed from Middle East supply disruptions affecting petrochemical supply chains. Spandex fibre and thermoplastic polyurethane elastomer demand is growing with expanding activewear and athletic footwear market activity.
The main upside risk is a sharp butanediol and tetrahydrofuran cost increase alongside accelerating spandex fibre and polyurethane elastomer demand growth. The main downside risk is continued Chinese PTMEG production capacity additions and weak European textile demand that limits the global price recovery.

Spandex and elastane fibre production takes the largest share, where it forms the soft segment of polyurethane fibre for sportswear and activewear. Thermoplastic polyurethane elastomers, cast elastomers for industrial equipment, adhesive formulations, and high-performance polyurethane coatings also consume significant volumes.
The Q2 2026 average was USD 3.12/KG in the United States, USD 2.38/KG in China, USD 3.62/KG in Germany, and USD 2.98/KG in India. Germany remains the highest-priced market.
The global average rose from USD 2.493/KG in Q1 to about USD 2.618/KG in Q2, a gain of around 5.0%. Firmer tetrahydrofuran feedstock costs and spring spandex demand drove the H1 firming.
Seasonal moderation in spandex fibre procurement reduced buying urgency. Adequate tetrahydrofuran feedstock supply maintained comfortable production economics before the Q4 2025 and H1 2026 demand-led recovery.
The global average is expected in the USD 2.64 to 2.90/KG range for H2 2026, with continued firming as tetrahydrofuran feedstock costs stay elevated and spandex and polyurethane elastomer demand grows.
Germany sits highest on tetrahydrofuran and energy costs, the United States and India hold a firm middle on spandex and elastomer demand, and China prices lowest on large domestic production capacity.
This report is updated monthly. For real-time pricing intelligence, contact the Expert Market Research team directly.
Prices respond mainly to tetrahydrofuran and butanediol feedstock costs, spandex fibre production season cycles, and polyurethane elastomer sector demand. Middle East supply events and fashion and activewear market trends are key signals.
Asia Pacific leads with China holding the largest ring-opening polymerisation capacity, followed by North America and Europe. Any tetrahydrofuran or butanediol cost shift ripples across markets within one to two quarters.
Buyers can use quarterly trends and forecasts to time spandex fibre and polyurethane contracts around production season cycles, build cover when tetrahydrofuran signals tightening, and monitor butanediol cost trends as the primary upstream signal.
