Topaz PURABLE: Membrane systems and functional layers on the basis of water-borne formulations

Topaz PURABLE membrane systems are formulated on the basis of specially developed, purely water-borne raw materials, yielding a new generation of breathable components for multilayer functional textiles.Trans-Textil completely dispenses with organic solvents along the entire supply chain and in production and processing, resulting in a significantly reduced ecological footprint that encompasses the making-up process, utilisation and disposal at the end of the primary life cycle. PURABLE systems combine performance with a new level of sustainability in functional composite fabrics.

Topaz COMPANION® 3D – Fiber-based 3D membrane systems

The basis for the outstanding properties of the Topaz Companion® membranes is their fiber-based 3D structure made of specially developed high-tech polyurethane. The microporous structure in the nano range combines technical performance and comfort with high ecological standards. The new membrane systems are highly breathable, ultra-light, elastic and waterproof, even after several washing cycles. The certificate according to STANDARD 100 by OEKO-TEX® confirms the human-ecological harmlessness. Topaz COMPANION® 3D systems thus become the basis for ultra-light laminate composites with high wearing comfort and reliable weather protection for daily active use in outdoor, sport, fashion and leisure.

Topaz bimicro®

Trans-Textil is placing a further new development on the market in the form of the Topaz bimicro® membrane. This unprecedented product combines the characteristics of a microporous ePTFE membrane with those of an equally microporous protective polymer layer for high water vapour transmission and variable air porosity at high water impermeability. Topaz bimicro® can be optionally upgraded with Cocona® natural technology™ utilizing activated carbon derived from coconut husks.
