Milan/Italy – Maire has recently announced that Nextchem, through its subsidiary Conser, the technology licensor for high-value chemical derivatives and biodegradable plastics, is reinforcing its portfolio with the introduction of the new NX Conser Polyflex technology to produce polytetramethylene ether glycol (PTMEG), the key polymer composing the spandex fiber.

This technology is part of the newly created Nxpand suite, that is marking Nextchem’s strategic entry into sustainable solutions for the textile industry. NX Conser Polyflex encompasses versatile solutions to produce PTMEG from both conventional and biological feedstock (i.e. bio-based tetrahydrofuran or THF). PTMEG is then used to manufacture a variety of elastomeric products, including spandex, known for its outstanding flexibility and thermal/mechanical resistance, making it essential for applications in high-growth markets such as sportswear, technical apparel, and protective clothing.

The initiative builds on Nextchem’s collaboration with Shanghai Diyang Chemical Technology Co., a Chinese company specialized in catalysts and fine chemicals. The agreement also includes solutions for special intermediates as well as industrial, pharmaceutical and cosmetical solvents.

Fabio Fritelli, Managing Director of Nextchem, commented: “NX Conser Polyflex represents a major step forward in expanding our sustainable technology portfolio. It reinforces our commitment to delivering innovative solutions that support the high-performance textile industry and unlock new opportunities for the group in fast-growing segments.”
