Premiere: BenQ Materials Develops Xpore Membrane

BenQ and Picture Organic Clothing Present New Membrane

BenQ Materials of Taiwan announces the introduction of the Xpore membrane, a new sustainable technology for waterproof and breathable textiles. It was presented for the first time at the ISPO Munich 2020 in cooperation with the French Eco-Snow- and Streetwear Brand Picture Organic Clothing.

Im Demain Ski-Outfit der HW/2020 Kollektion von Picture Organic Clothing kommt die Xpore Membran erstmals zum Einsatz.

Membrane without PTFE and PCE

The hydrophobic and nanoporous membrane consists of polyolefin and contains only carbon and hydrogen. It is free of PTFE and PFC (polytetrafluoroethylene and perfluorohydrocarbons) and is also completely solvent-free in production because Xpore is stretched mechanically and not chemically. Since the Xpore membrane contains only hydrogen and carbon, BenQ Materials says that no harmful chemicals or gases are released during the thermal treatment for recycling. "On the contrary," says Stella Lin, Digital Marketing Manager at BenQ Materials Corporation. " A PTFE membrane contains fluorine and a PU membrane contains nitrogen, both of which cause harmful substances during thermal treatment for recycling. In short, it is possible to recycle the Xpore membrane together with textiles, without the creation of harmful substances during thermal treatment."

Many Possible Applications

Xpore not only wants to set a new standard for environmental friendliness from the production process to the end product, but also offers true breathability together with waterproofness, the company says. In addition, Xpore technology is suitable for classic functional textiles made of synthetic fibres, and - according to BenQ - it is also particularly suitable for natural fibre fabrics such as silk, wool and cotton as well as for special fabrics, even leather. Xpore technology materials, including nanoporous membranes and adhesives, have already received important SGS and ITS certifications. The BenQ Materials facilities are ISO certified. Bluesign, Oeko-Tex and TAF of laboratory approvals are in process, BenQ continues.

Focus on Recycled Raw Materials

However, the membrane is not biobased, as can currently be read in some articles. "Xpore cares a lot about environmental friendliness. Although Xpore's current raw materials are not bio-based, we plan to use recycled raw materials to manufacture membranes and produce even more high performance materials in this and next year. Our target is to use 30 percent recycled materials in the manufacturing process by the end of 2024," Lin continues.

Picture Organic Clothing as First Brand Partner

As the first brand partner from the sportswear sector, Picture Organic Clothing presented a first ski outfit with the new membrane at the ISPO Munich 2020. Company founder Julien Durant: "This membrane is a real alternative and offers the best performance-sustainability ratio today. With Xpore we have a product that offers similar performance in terms of waterproofing and breathability to other membranes".
