NEXTCHEM expands polymer portfolio with sustainable PTMEG technology, supporting spandex production and strengthening its position in high-performance textile markets.
MAIRE (MAIRE.MI) has announced that its sustainable technology arm, NEXTCHEM, is broadening its advanced polymers portfolio with the launch of the NXPand™ suite. As part of this strategic expansion, NEXTCHEM, through its subsidiary CONSER, has introduced the innovative NX CONSER PolyFlex™ technology designed to enable the production of polytetramethylene ether glycol (PTMEG), a fundamental polymer used in the manufacture of spandex fiber.
CONSER, recognized as a technology licensor specializing in high-value chemical intermediates and biodegradable plastics, is strengthening its offerings by adding this advanced PTMEG production solution to its portfolio. The introduction of NX CONSER PolyFlex™ reflects NEXTCHEM’s commitment to advancing specialty chemical technologies that align with evolving sustainability and performance demands across industries. PTMEG is a critical raw material in the production of spandex, a synthetic fiber valued for its exceptional elasticity, durability, and resistance to heat and mechanical stress.
The newly launched technology is part of the NXPand™ suite, a platform that represents NEXTCHEM’s strategic move into sustainable innovations tailored for the textile sector. Through NXPand™, the company aims to address the increasing demand for environmentally responsible production methods while maintaining high standards of performance. NX CONSER PolyFlex™ provides flexible process configurations capable of producing PTMEG from both traditional petrochemical feedstocks and bio-based alternatives, including bio-derived tetrahydrofuran (THF). By enabling the use of renewable raw materials, the technology supports reduced environmental impact and aligns with the global push toward greener supply chains.
PTMEG produced through this process serves as a key ingredient in the manufacturing of elastomeric materials, particularly spandex fibers. Spandex is widely used in applications requiring stretchability, strength, and resilience. Its unique properties make it indispensable in fast-growing segments such as sportswear, athleisure, technical textiles, medical fabrics, and protective garments. The superior flexibility and thermal stability of spandex enhance comfort and durability, meeting the performance expectations of both consumers and industrial users.
The development of NX CONSER PolyFlex™ also builds upon NEXTCHEM’s collaboration with Shanghai Diyang Chemical Technology Co. Ltd, a China-based enterprise specializing in catalysts and fine chemicals. This partnership strengthens the technological foundation of the new offering and broadens the scope of solutions available to customers. In addition to PTMEG production technology, the agreement between the companies encompasses the supply and development of solutions for specialty intermediates as well as solvents used in industrial, pharmaceutical, and cosmetic applications. This integrated approach enhances NEXTCHEM’s ability to serve diverse end markets with advanced and sustainable chemical processes.
Fabio Fritelli, Managing Director of NEXTCHEM, highlighted the strategic importance of the launch, stating that NX CONSER PolyFlex™ marks a significant milestone in expanding the company’s sustainable technology portfolio. He emphasized that the new solution underscores NEXTCHEM’s dedication to delivering cutting-edge technologies that support the high-performance textile industry while opening new growth avenues in rapidly expanding market segments.
Overall, the introduction of the NXPand™ suite and NX CONSER PolyFlex™ technology signals MAIRE’s broader ambition to position NEXTCHEM as a key player in sustainable chemical innovation, particularly within the textile value chain. By combining technical excellence with environmental responsibility, the company aims to capture emerging opportunities in advanced materials and contribute to a more sustainable future for the global textile industry.
