However, it is predicted that strict regulatory rules that prohibit the use of toxic and carcinogenic compounds, such as 1,4-butanediol, in the production of Polytetramethylene Ether Glycol (PTMEG), will restrain 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG) market expansion. It is anticipated that unstable raw material prices and the availability of low-cost replacements will impede 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG) and spandex market expansion.

COVID-19 has disrupted almost every industry, but due to the safety purpose, the demand for face masks and gloves was in high demand, which has led to an increase in the demand for the product. Face mask demand has significantly risen worldwide as a result of the new Coronavirus abrupt introduction since spandex is a crucial component in the creation of face masks.

Consequently, the business is anticipated to grow significantly over the forecast period. The ear loops of the mask are mostly made of spandex. An increasing number of consumer apparel and accessory producers in China, where the majority of face mask production is produced, are anticipated to significantly expand the market of 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG) throughout the projection period.

Textile Industry is Expected to Witness the Fastest Growth

The market expansion of 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG) is being augmented by the clothing and apparel sector's robust growth. Novel use of spandex in denim and rising demand for lingerie, athletics, compression gear, and other items are also predicted to boost the market growth of 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG).

Polytetramethylene Ether Glycol (PTMEG) is used to create high-quality polyurethanes with improved properties like resistance to hydrolysis and microorganisms, great performance at low temperatures, and strong resistance to physical wear.

Further, it is anticipated that rising demand would propel the development of textiles with greater stretch for a variety of textile applications. In June 2020, in conjunction with Kingpins24's virtual denim event, Hyosung introduced innovative creora 3D Max spandex. With the introduction of 3D Max spandex, Hyosung was able to give denim items dual performance characteristics that would last over time, including ultra-stretch and excellent recovery.

With the addition of extra elements like laser surgery and eco-friendly finishing, 3D Max jeans have a natural feeling and appearance. Thus, product launches based on the products in the textile industry are boosting the market growth of 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG).

Tetrahydrofuran (Thf) Accounted for the Highest Market Share in 2021

Due to the increased production of Polytetramethylene Ether Glycol (PTMEG), a polymer widely used to create urethane elastomers and fibers, the THF business has grown during the past few years. It is also a multipurpose solvent with a variety of uses, including in the production of printing inks, vinyl films, cellophane, commercial resins, and synthetic rubber. It serves as a PVC-type cleaner before joint formation and is only utilized in the manufacture of PVC-type concrete.

Spandex Application is Expected to Hold the Significant Revenue Share

The demand for spandex is anticipated to increase throughout the forecast period as a result of new medical uses for the material in the field of protective clothing and wound treatment. Due to the significant demand for the creation of stretchy sports apparel and fabrics, spandex is the most lucrative application sector for PTMEG. Due to their outstanding intrinsic qualities, such as high elasticity, durability, and more flexibility than rubber, these fibers are only employed in this manner.

The Demand in Asia-Pacific is Expected to Witness Significant Market Growth

Increased population, rising spending power, and developing end-user sectors are all predicted to contribute to the Asia Pacific region's 1,4-Butanediol (BDO), Polytetramethylene Ether Glycol (PTMEG) and spandex markets' rapid expansion. A growing number of end-use industries and the accessibility of cheap labor are expected to keep the Asia Pacific from losing its market share. A significant consumer is thought to be China because of rising disposable income.

The Tetrahydrofuran (THF) applications industry held the biggest market share and it is anticipated that this dominance will last during the projected period. The cause for this is the region's growing R&D activities, accessibility of a highly qualified workforce, cutting-edge processing and implementation technologies, and established infrastructure.

Recent Developments

In August 2026, Hyosung TNC announced its bio-based 1,4-butanediol plant in Ho Chi Minh City, Vietnam, has begun commercial operations, establishing an integrated manufacturing chain which links renewable feedstocks to PTMG and spandex production. The initial Bio-BDO facility has a stated production capacity of 50,000 metric tons annually, with infrastructure allowing expansion to 200,000 metric tons. Hyosung uses the Bio-BDO to manufacture PTMG at its Dong Nai facility before converting the intermediate into regen BIO spandex. The project strengthens vertical integration and supports the development of lower-fossil-content stretch fibers for apparel manufacturers. (Source: Hyosung)

In March 2026, BASF introduced a reduced-carbon-footprint PolyTHF product variant as part of a wider portfolio launch covering BDO, THF and NMP. PolyTHF is BASF's commercial name for PTMEG, an important intermediate in elastic fibers and polyurethane elastomers. The new product provides at least a 10% reduction in its product carbon footprint compared with the corresponding standard Ludwigshafen-manufactured product, while maintaining existing performance characteristics. This development is relevant to the integrated BDO–PTMEG–Spandex market because it creates an additional lower-carbon sourcing option for producers seeking to reduce their upstream material emissions.
