Mehler Texnologies is one of the internationally leading companies on the market for coated fabrics. We produce in our facilities in Hückelhoven and Fulda in Germany as well as in Lomnice in Czech Republic and distribute annually more than 50 million m² material under the brand names VALMEX®, POLYMAR® and AIRTEX®. Our customers are found in processing industries. More than 60 years of development and production experience are the basis for our mature products. Continued research and development improve existing compound materials and open new application areas.
A stable quality for all our products is achieved by our state-of-the-art weaving and coating machines. Constant quality monitoring in our laboratories, intense dialogues with planners, manufactures and processors in different market segments and industry branches prove our close and trusting cooperation with our customers.
Mehler Texnologies, as a pioneer in this area started in 1944 with the coating of PVC-Polyester membranes and were “one of the first” to improve the special PVDF lacquering techniques, today synonymous with long-term cleanability and added long term UV protection. Mehler Texnologies has acquired a wide range of expertise and experience in the field of membrane architecture materials and is specialized in textile products for particular uses.

The Fabric –Materials properties : A coated structural fabric usually consists of a woven base cloth stabilized and protected by a coating on both sides. The base cloth consists of warp threads running the length of the roll and weft threads running across the width. A mesh fabric is a coated cloth with spacing between the thread bundles. Sometimes mesh fabric can also refer to a woven shade cloth where precoated threads are woven into cloth.
For the engineering of tension structures, the most common choices are PVC coated Polyester cloth materials. High quality low-wick treated PVC-Polyester fabrics generally have a structural lifespan in excess of 20 years. On ordinary materials the plasticizers in the PVC migrate towards the surface over a period of time making the surface harder to clean. The PVC coating contains additives that include UV stabilisers, fire retardants, colouring and fungicidal agents. Mehler quality materials under the brands Valmex® Mehatop are a choice of protective PVDF (Fluorinated Polymer) lacquers that enhance the cleanability of the PVC membrane.
To improve this and maintain translucency, Mehler is offering a range of products including PVDF lacquer on both material sides, perfectly weldable. The choice of a suitable material is dictated by many characteristics, ranging from technical and mechanical properties to the aesthetical appearance, coming from physical material properties.

The textile industry is constantly improving the existing materials. Mehler Texnologies as a pioneer fabric producer is continuously increasing and perfecting those materials in each aspect. There is a wide range of products which are very suitable for particular uses, depending on the specific project needs and the particular defined use (ex. façade shadowing or roof covering, etc.). Regardless of the fact that each material can be used for textile roofing we suggest our customer contact the specialized industry and proceed to this choice after particular analysis of all project characteristics, in order to assure the best possible decision taking into account the aesthetics, the mechanical/static load properties and the economical aspect of the project.
In the architectural segment, membranes made by Mehler Texnologies are multilayered composite materials with special densely woven low-wick yarns in base fabric. The double thread woven fabric, commonly described as “Panama” weave, varies depending on the mechanical resistance requested by the customers. The different membrane materials are graded by weight and strength. Mehler Texnologies materials are basically ”pre-stressed” with different force grades in both directions. The warp direction (length of the material roll) has less stretch to stabilize the elongation in this sense. The weft direction (the width side of the material roll) has more stretch in order to absorb the orthogonal tension more readily during the distensile installation process. Professionals like to maneuver the compensation ratio of the fabric material during the patterning process in order to generate ad-hoc geometries and unique smooth surfaces. This process is generally considered “top secret” to most of them and is also the core of the well qualified textile architecture engineer or specialized manufacturer. This requires a certain kind of technical information generated by computer analysis, simulation and testing processes, generated case by case for each project.
Mehler can provide to the customer biaxial results for each produced batch of material. The tests are executed on client request at the accredited laboratories based on MSAJ/M-02-95 procedure.
